EDIT 2009/12/11: Microsoft Provides a tool to do this for you – Windows 7 USB/DVD Download Tool which is available for download here.  If you need instructions on how to use the tool, see the Microsoft Store Help on the ISO-Tool (http://store.microsoft.com/Help/ISO-Tool).

It surprised me to find that there are very few dead-simple guides to creating a bootable USB thumb/pen/flash drive for a Vista and/or Windows 7 installation.  I cobbled together the following from VistaPCGuy and another source I don’t remember right now.

This will walk through the steps to create a bootable USB flash drive for the purpose of installing a Vista or Windows 7 OS.  These instructions assume that you have a computer with Windows Vista installed on it.


  • USB Flash Drive (4GB+)
  • Microsoft OS Disk (Vista / Windows 7)
  • A computer running Vista / Windows 7

Step 1: Format the Drive
The steps here are to use the command line to format the disk properly using the diskpart utility. [Be warned: this will erase everything on your drive. Be careful.]

  1. Plug in your USB Flash Drive
  2. Open a command prompt as administrator (Right click on Start > All Programs > Accessories > Command Prompt and select “Run as administrator”
  3. Find the drive number of your USB Drive by typing the following into the Command Prompt window:
    list disk

    The number of your USB drive will listed. You’ll need this for the next step.  I’ll assume that the USB flash drive is disk 1.
  4. Format the drive by typing the next instructions into the same window. Replace the number “1” with the number of your disk below.
    select disk 1
    create partition primary
    select partition 1
    format fs=NTFS
    When that is done you’ll have a formatted USB flash drive ready to be made bootable.

Step 2: Make the Drive Bootable 
Next we’ll use the bootsect utility that comes on the Vista or Windows 7 disk to make the flash drive bootable.  In the same command window that you were using in Step 1:

  1. Insert your Windows Vista / 7 DVD into your drive.
  2. Change directory to the DVD’s boot directory where bootsect lives:
    cd d:\boot
  3. Use bootsect to set the USB as a bootable NTFS drive prepared for a Vista/7 image. I’m assuming that your USB flash drive has been labeled disk G:\ by the computer:
    bootsect /nt60 g:
  4. You can now close the command prompt window, we’re done here.

Step 3: Copy the installation DVD to the USB drive
The easiest way is to use Windows explorer to copy all of the files on your DVD on to the formatted flash drive.  After you’ve copied all of the files the disk you are ready to go.

Step 4: Set your BIOS to boot from USB
This is where you’re on your own since every computer is different. Most BIOS’s allow you to hit a key at boot and select a boot option.

I used these instructions to get my new Dell Mini 9 laptop loaded with Windows 7 (the PDC bits).  HTH.

    i dont tell many people that, but this info on making the usb drive bootable with running bootsect from the dvd to the usb, then copying all files to usb drive and booting from it was not anywhere else i looked, becuase i was trying to just straight copy all files to usb and boot from it but was getting an error saying remove disks or other media. THANKS AGAIN

    • I'm glad it was helpful! It took me way too much searching to find this info myself so I thought it would be good to share.

      • Listern

        I have a problem on step 2. Step 1 is all ok but when i try to use bootsect it said:
        Target volumes will be updated with BOOTMGR compatible bootcode.

        Could not map drive partitions to the associated volume device objects:

        How to fix that? Drive formatted all ok, i am sure of it

    • raiderj

      This guide worked great to install Windows 7 onto my Dell mini (using Winxp instead of Vista). What I did was make sure the USB stick was formatted NTFS, then run bootsect, copy the files from the Win7 ISO, then boot off like normal!

    I have no idea what to do for an XP installation; I found a lot of information on making bootable XP disks when I was searching for instructions for making Vista-bootable USB keys. Google's your friend here b/c I can't help. :(

  • Lee

    this info is good is you got vista already install on it but what about if you got win xp and want to make a bootable flash drive to install vista from scratch. Can someone help.

  • racethesun

    If you cant get XPs diskpart to find your disk, just format it in FAT32, then use CONVERT in command prompt to convert it to ntfs. After the disk has been converted continue to step 3. Tested it on my machine and worked fine on the first try.

  • kmwoley

    That's a good question; I haven't looked at how to do that yet since I don't have any XP boxes. If you find a good way, please let me know.

    • mike

      Why cant you use the bootsect from a windows 7 disc and then just copy the XP files onto the drive and load it.. Im certainly going to try that right now.
      already loaded 7 like this yesterday.

  • whs

    Tomorrow Jan 9 will be the first time I will try to download the W7 ISO. When you talk about the "Microsoft OS Disk (Vista / Windows 7) " are we talking about the ISO disk I can burn from the ISO file or do I have to slipstream something with my Vista disk and the ISO file? I have only a Vista recovery disk that I burnt from the recovery partition.

    • You can do everything here with the Windows 7ISO that you'll download from Microsoft. Probably the easiest thing to do is mount the ISO and use it as a disk, or just burn it to physical media. You won't need a Vista disk as the Windows 7 disk will have everything you need.

  • whs

    Thanks for the answer. That makes it really easy. If it works, you have done all of us a real favor.

  • whs

    I got thru step 1 with one small problem – in "create partition primary" you have to add size=3800 (which would be 3.8GB) or whatever is right for your stick. Without "size" you get an error. But step 2 does not work at all. The cd command does not seem to do anything, at least there is no reaction. The bootsect or bootsect.exe produces an error "'bootsect.exe' is not recognized as an internal or external command, operable program or batch file." I am puzzled because this is a completely legal command. So I am stuck. Any push would be appreciated.

    • racethesun

      remember that in windows command prompt to change from one drive to another you cant use cd, you just put in the drive letter. So to change from C: to E: just put "E:" without quotes, then from there you can use "cd boot" and that should get you to bootsect.exe

    • That's interesting: I wonder what it is that causes you to have to specify the size when creating a partition? I've never had to do that before.

      You're right that my directions should have explicitly stated that you have to change to the drive first by typing in the drive letter. I'll get that updated.

      • YAY-I-FIXED-IT

        I ran into the same issue, the solution i found, was i didnt do a step you mentioned, once i did that it worked. Not sure why but what that option does made it happen.

        at step #4

        select disk 1

        " i didnt do the clean step then i got the boot size error, on my fat32 partioned flash drive.

        I re-ran "clean" started over those steps then it did not ask me for any size or anything and workd as yours listed did.

        What does "clean" actually do, im not sure i havent read up details for it, but that made the next step work with no added details of any size issues or putting in any numbers an such for it.

  • JRaig

    Your procedure is simply brilliant, thanks a lot kmwoely

  • Another satisfied customer. I had been roaming around google piecing something together. I had the files on my USB drive but it wouldn't boot. Tried the bootsect command you listed and it executed, but still couldn't boot. The difference was that my USB drive was formatted in FAT32 instead of NTFS. So it is important to format your drive as NTFS.

    Thanks again for the guide.

  • […] Creating Bootable Vista / Windows 7 USB Flash Drive at Kevin’s Blog. Share: […]

  • whs

    Adam, there are some threads that suggest that Fat32 also works. In fact, they explicitely format the USB in Fat32. I myself have not tried that though.
    For the second step (loading the ISO on the USB) i have used a slightly different approach. I unzipped the ISO file with WinRar and just moved the files over to the USB. That worked perfectly. And then there is always this command: xcopy x:*.* /s/e/f y:

  • rlh

    hi how do i create a boot partition on my 4gb pendrive so i can install vista , typing list disk in command prompt only shows my internal sata drives and external usb drives and not my pen drive. in disk management it is showing as drive 7 . but drive 7 is not listed in cmd? what am i doing wrong??

    • GO義勝

      I ran into the same issue on both of my XP systems. I did a "list volume" instead and got a listing of all of my system drives. Anyone know why this may be the case for some of us?

    • iyusaf

      I think you need to head into Device Manager and configure your removable drive for Optimize For Performance instead of Optimize for Quick Removal. I had to do this myself before I could format the drive as NTFS.

  • whs

    In command prompt, first type DISKPART and hit Enter, then type LIST DISK and hit Enter, then take the number it shows you there for your USB If you have several USBs in the system, you can only make the correlation by the size. If necessary, you may have to unplug other drives that have the same size. Onc you have the number, you use this for the SELECT DISK command.

  • lth

    maybe show us how to format with the QUICK option?

  • Well this works for 32 bit os if i am using a 32 bit os already … can anyone tell me how to do it to a 64 bit os from a 32 bit?

    As in my case I am running a 32 bit Vista.I want to install 64 bit Win 7 to another hdd.But the bootsect is not possible to be executed from within my 32 bit OS.Any ideas?

    • Really, the only problem you've got is that you can't run the 64-bit version of 'bootsect' which is on your Windows 7 installation media from your current 32-bit OS.

      If it were me, I'd download a 32-bit copy of Windows 7 just to get the 32-bit version of 'bootsect' and you'll be able to party on from there. Or find a friend who's got a 32-bit Vista disk you can borrow. :)

    • Kristoffer

      Actually, you don't need the bootsect part, it will boot anyway. I have used this method a couple of times without bootsect so i can vouch for that.

  • whs

    Dark Prince, I would suggest you run the 64bit in a virtual partition. Install VirtualBox (I found this to be the best performing) on your Vista. You can install W7 directly from the downloaded ISO file – takes 35 minutes (no need for a DVD or USB). Performance is very good (I allocated 1.4GB of my 3GBRAM to the virtual partition) and you can switch between W7 and Vista with 1 click. You just have to give Superfetch a few minutes to reorder it's files for Vista after you started VirtualBox. That's why I keep the virtual partition running all day because once the system settles down, performance is good on both sides (host and guest).

  • Tony

    This is great info, but does anyone know how to make it to where you can install the OS itself on the flash drive then boot into it like you would with your main OS? It's fairly easy with XP and extremely easy with many flavors of Linux but I can't find anything for 7. Any tips?

    • Gabe

      You're running bootsect from the usb stick itself. Don't. Run the bootsec on the CD image which should be a different drive from the usb disk.

    • rich

      you need to run cmd using 'run as administrator'.

    • Roger

      type cmd in the vista run box and then hold down ctrl and shift before hitting enter, you will now run a command prompt in administrator mode. It then worked for me.

    • Damon

      run it as administrator.

      • christopher-michael

        For anyone having difficulties running cmd as administrator (even when using control shift enter) you can click on Start -> All Programs -> Accessories and RIGHT click on the Command Prompt and select Run as Administrator. You will then get the aforementioned box to allow the program to run at administrator level. The commant prompt will come up with C:Windowssystem32 to run as an administrator instead of using your personal account path as it would when not running under Administrator.

        Even with the control + shift + enter it was simply opening the command prompt outside of administrator level. Yes what was suggested is supposed to be a shortcut but it seems to not work for many like myself as I found in other forums. But take this slightly longer way and it should work for you.

    • Warren

      You have to find command.com, right-click it and select "run as administrator" then it will work fine.

  • iyusaf

    Great job. Thanks!

  • ReFLeX

    Hey nice tutorial but sadly it only works if your using Vista to do all this, I tried it on my desktop that has Xp 64-bit and it wouldn't show my USB as a disk when I typed 'list disk', so I took it to my laptop which has Ultimate and it worked like a charm :D. Thanks!

    • Manish SIngh

      Yep WIn xp or Windows Server 2003 won't display USB disks as disks in the diskpart utility.

  • Colin

    All I want to do is boot vista32 on a flash drive. Not install. Would these instructions allow me to just boot up on vista with a different config than is on my PC currently?
    What I really want is to be able to book two different configurations (not 2 different Operating systems). I created a new boot BCD, but couldn't see how to make two different configs. So, I looked at booting from a flash drive. Any help would be appreciated.

    • I think google is going to be your friend here. I don’t really know anything about booting Windows off of disk or flash media, let alone booting it with different ‘configurations’.  I’m honestly not even sure what you mean there.  I just wrote up these instructions because it was hard for me to figure out how to create bootable installation flash drives.

  • Sacramento Rich

    Following you instructions, I was able to successfully make my 32gb Flash drive bootable. But I want to run Windows7 from my Flash drive. When I get to the “Where do you want to install Windows” screen, it doesn’t see the flash drive. Any help would be greatly appreciated.

    I want to put both Win7 plus all my other apps and files on a Data Traveler 100 USB stick for travel. In this case would I format a bootable partition for Win7 and a separate partition for my apps/files? Can I use Disk Management utility to do the partition/format, then follow above steps to make the Win7 partiton bootable? I am told that multiple O.S. can be stored and booted from same USB with a boot manager, but I don't think I need that since I just want Win7 plus my apps/files so two partitions should be fine – one bootable, one not. NTFS format both?

    • racethesun

      You dont have to make two partitions, everything can go on one partition on the usb stick.

    This is a great write up, however the title is misleading. It reads like we can create, install and boot Vista/Windows 7 from a flash drive, rather than the hard drive. My only option is to install to the hard drive, but I can boot to the flash drive as if it were the DVD in the drive, and install it on the laptop's hard drive (in my case, my Mini 9)

      I am getting the same thing on one p.c. that is real old and won't accept it's BIOS upgrade. I think it is the machine. Try it on another computer with updated BIOS and you might be surprised. I have used this method to install to 4 p.c.s and laptops.

  • Thank you so much for this guide. I've used it about 6 times.

  • Another method now is to use Ultra ISO (trial) and under Bootable tab, select Write to Drive and it will burn it like a disk, yet you can still put other files on there (like with this method) as long as you don't mess with the ISO files which must remain out in the root.

  • envador

    Thanks gregrocker!!! I'm doing this right now…. on an XP machine, my 4gb sony usb wasn't showing up with diskpart / list.
    UltraISO is writing the disc image to my usb drive right this moment!

  • gregrocker

    Also remember that you need to enable boot from USB drive in your BIOS. This can be tricky since an old BIOS may not be ready to recognize USB, so check for BIOS updates (try your manufacturers support page for your computer via 1)serial or 2)model; at Intel downloads you can check using your motherboard model; get motherboard and BIO's ID and version numbers using Belarc Advisor freeware. Also tricky is that many bios view flash USB as a hard drive, so you may need to look at your hard drive listings under Boot tab in BIOS to see if it recognizes your flash there. If so, set it as first boot, or look in the temporary F10 settings (on some mobos) which let you choose boot-up devices on a one-time basis.

  • BOZ

    Worked for me WITHOUT Vista/7. I formatted my flash drive with XP to Fat32 and then used the ISO/DVD bootsect like you said to make it bootable. Works like a charm.

    This worked for me to install Win7 on an older Dell GX260, but I can't get it to work on another PC. Whenever I try to boot from USB is says "Invalid Partition table". Since I was able to do an install off of this USB key could it be an issue with a BIOS setting? This PC has an Asus P4P800 mobo. Or could somehow the partition nave been made unactive?

    • Greg

      Not all computers will allow boot from USB. BIOS settings need to be studied carefully, Google to determine relevance. "Enable USB legacy support" and "Enable Boot from USB" are the obvious ones. Under the boot tab, USB must be selected as first boot device; it may be detected under HD and not "removable device." Some Bios offer first boot device in temporary settings booted off of F10 or such, often listed at boot up.

      If all attempts fail, check for a bios update for your model on manufacturer's support page – it will normally say something about USB in the change table if it applies to this issue. A last resort is the manufacturer of your bios model, determined by running Belarc Advisor freeware. Follow instructions carefully, take all backup precautions and determine in advance emergency recovery procedures for bios flash.

      You have already determined the USB stick will boot on another computer, so that doesn't seem to be the problem but if there were any question about the stick's bootability the best check is to resinstall using UltraISO's trial new Bootable>Write Disk Image options.

      • Greg

        To clarify, check for bios update first on your computer manufacturers support software download page. Last resort, check on bios manufacturer's page. Run the Belarc Advisor to determine BIOs model, then search the model; for example on an Intel board, you search for mobo software on Download Page. Your computer manufacturer may restrict some bios updates for proprietary reasons.

    Can't find CD/DVD driver error appears after booting from flash drive. I tried going to Windows drivers but no luck with the one that shows up. Anybody else have this problem. I've tried to boot from my original Windows RC disk, but I can't do it?

  • […] Secondly, one you bought this pocker pc, say it has been three years & you want to do some reformat, I think the easiest option to ‘fresh install’ it with windows OS is through the usb port. (Maybe you can use wifi.. I don’t know) I think you can use the portable plug n play cd-rom, where you just plug it to usb port, put your windows cd & boot..done..easy rite?? But what I want to highlight today is by installing windows using a bootable pen drive. So, can you use a pen drive to reformat your computer??? I think yes because I’ve come across this article with a clear n concise tutorial on how to install windows vista/ 7 thru ur pen drive (Here). […]

    Thank You for such detailed instructions on creating the bootable flash, however my laptop has Vista pre-installed, so I do not have the Vista OS disk…. How can I proceed without it????

  • greg

    No need for Vista disk. Just download UltraISO trial and load the Windows 7 ISO, then from Bootable tab select "Write Disk Image" to your USB flash and it will format and install Win7 installer on your USB. Works every time. The above comments handle almost every other possible hitch.

  • Simon

    Does this mean that we can`t acually run Win 7 from the usb stick, like Linux, OSX, Solaris etc , but the only option is to install to an NTFS partition on your hard drive…?

  • @Deborah – If you extract the ISO to a DVD you will have a Win7 disc, which will have bootsect on it :)
    Just finishing installing it on my new Samsung N110, thank you very much!

  • Art

    Thanks for this great guide!

    My mom got an Dell PC from her boss who was replaced them with newer ones. They deleted everything on it, even the partition! So I had to put the harddrive in my Vista PC and there I created the partition. After putting it back it said bootmgr missing.

    And somehow the BIOS was messed up that it couldn't start the Windows 7 DVD. But I'm so happy I found this guide, now I am installing it from my 4GB flash drive!


  • Joe

    I followed the guide but got an error:

    "Windows failed to boot" "File: bootbootbcd"

    Seems like the usb is bootable, but the second level mbr is not properly set by the command "bootsect /nt60 g:"

    I am running Windows 7 64bit, and I am trying to create a newer Windows 7 build, but it's 32bit. Maybe working under 64bits and 32bits is not a good idea. That's the most suspicious thing I could think.

  • jade

    Hi. im pretty sure i did all the steps correctly and got the usb bootable drive working. Im trying to install it to my dell mini 9 but got stuck till the part of WHERE i'm suppose to install it. there were 2 options in the setup; 1) partition 0 (OEM something2…) which is less than 1gb and another 2) partition 0 (system) with 14.3 gb. and i cant proceed. Did i miss something? I'm totally lost. right now, im googling to find some answers. Would be great if anyone could help me out please.

    • Your best option would be to use the 14.3 GB partition and leave the smaller one alone. The smaller one likely contains the Dell recovery/diagnostics tools which I've found (marginally) useful. If you really want/need all the space, delete all the partitions and start fresh.

  • no CDdrive

    1. Insert your Windows Vista / 7 DVD into your drive.
    2. Change directory to the DVD’s boot directory where bootsect lives:
    cd d:boot

    Ok so with these steps it sounds like your cd drive has to be working but mine is not, hence why I want to boot from the usb. Am I wrong in assuming this? Can I do these steps on another computer and then use the usb on the one that has the broken cd drive on it? Any input would be appreciated. Thanks.

    I'm currently running Vista 32 bit and have downloaded a copy of Win 7. The following instructions work really well for me until I get to bootsect /nt60 l: I get the following error – "This version of j:bootbootsect.exe is not compatiable with the version of Windows you're running. Check your computer's system information to see whether you need a x86 or x64 bit version of the program and then contact the software publisher."

    Any suggestions? And thanks for the awesome guide!

    • You likely are running a 32-bit Vista and trying to run the 64-bit version of bootsect. You need to have the 32-bit version of bootsect.

      • Adam

        I figured that was probably my problem. For the life of me I can't find a bootsect for windows 32 Vista. Do you know where a 32 bit version is avaliable?

    I tried using this method with my antique 4GB ipod nano. First with ntfs, then with fat32 (Took much longer to copy the dvd files unto the usb drive). Still can't get the computer to boot from the usb.

    My bios has usb fdd/zip/cdrom/hdd options, but neither works. I also tried just using the boot menu (f12), and everyime I get win xp booting from my hard drive, even when it is not enabled anywhere in the bios boot order.

    I've been trying the usb approach after every try I've made with dvd ended with error 0x80070570, even though I am %100 sure my medias were ok, and so is the dvd drive (Used the exact same media elsewhere, and tried connecting a drive that I used elsewhere also).

  • Fellow

    For those wondering how to format your stick with the quick option, the command is as follows:

    format fs=ntfs quick

    Thanks alot for the guide!

  • rob

    Is the point of this to temporarily boot off the USB as opposed to the Hard drive? If so, I suppose that would be a good way to give Windows 7 a test drive :)

    Really Silly question: Can I have a single 8GB USB bootable stick for both Windows 7 and Windows 2008 installations? Appreciate your help.

  • Kenny

    Hey I followed the instructions up til the point were I have to use the boot sect. I used the "bootsect /nt60 g:" but I got the following error

    Drive g: maps to volume DeviceSCDEmuSCDEmuCd0.
    This volume does not appear to connect to any disk partitions. Volume bootcode
    is always unused in the absence of associated partitions.

    so I went to "My computer" and realized it was a assigned a different letter "j"
    , so I entered "bootsect/ nt60 j:" and it said that it was successful. so my question is Did I do it right?

  • xfatherjack

    Great post. I followed you instructions.
    It allowed me to INSTALL Win7 on to a USB, Now I can INSTALL Win7 from my USB.
    What I wanted to do was to BOOT from my USB, with Win7 INSTALLED on the USB (as if there was NO HARD-Drive in my computer) ANY IDEAS!!!

    • Patanjali

      No, you didn't install Win 7 on the USB, but just made the USB bootable and duplicated the Win 7 install files to the USB.

      You need another USB to actually install to, though I suspect that Windows would run very slow, as USB keys do not have good read and write times, and assuming you have enough GBs to run in (like 16GB+).

  • Fantastic – Am now running Windows 7 Ultimate on my Acer Aspire one 751h. So far, running way smoother than Vista Basic was!

    I didnt even need to boot onto the USB drive – I ran the Setup.exe from the USB drive right in Vista, chose a custom install, selected the main drive, and it installed without any issues at all.

    Way easier than I thought it would be.

    This worked, and the install process took a LONG time.

    It said it would restart a few times, so I go back to see what progress it has made, and the thing has restarted to the BEGINNING of the install process.

    Any ideas?

    • Assuming that you mean the Windows 7 install, then, yes it an take a long time… I'm not an expert in it, but I've seen it take an hour on some systems and four on others. There are always 3 restarts (I think) and that shouldn't change. I highly doubt it restarted from the beginning (it can't) it probably just took a long time.

  • DNA

    Use UltraISO, it's much simple:

    1. run UltraISO as administrator.
    2. mount your windows image using virtual cd.
    3. in UltraISO click 'File'->'Open CD/DVD…', then select the mounted drive and press 'Open'.
    4. click 'Bootable'->'Write Disk Image…'.
    5. in "Disk Drive", select your flash stick drive. in "Write Method" select 'USB-HDD+'.
    6. Click on "Write" button, wait until it end. and that's it.



    • Thanks, DNA. I haven't tried this method myself but I've heard others have had success with this. I'll try it myself and see what kind of success I have. If it works, I'll update the main post with instructions.

    does not work for me.. usb 8gb formatted in NTFS ( successfully formated partition using GPARTed), as the DISKPART does not show my usb in DISK LIST (although it is shown in VOLUME LIST (?!) used the tip shown here (the BOOTSECT part) everything is successful until the booting.. NO BOOTABLE PARTITION IN TABLE shown again…

    Any solution for this?
    I really think it would be very nice to install a Win7 for no more than 20 min ;) , so i need this :)

    • Igor

      I MUST SAY.. I'm using XP for making all of the above.. if this is the error, could anyone explain how to do this in XP…

  • Igor

    I found a solution using Gparted! (if DISK LIST does not list your USB)
    1.USB 2G formated in FAT32 **it has ti be FAT for the gparted program.
    2. A 4G USB (optim. for PERFORMANCE for NTFS FORMAT capability.
    3. Gparted *i did this with it
    get it here:
    4. follow my instructions:

    – Unzip the Gparted on the 2G usb *FAT32
    – go to utils, win32 and run file named MAKEBOOT.bat
    – restart and boot pc wia this usb
    – Gpart will boot, and You should now insert the other USB (4GB)
    – refresh, select THE 4GB usb (beware if you select the 2GB usb or your HDD you could get in real trouble!!
    – Create a partition table
    – New Partition – Primary, NTFS
    – APPLY
    – again, select the 4GB usb, EDIT FLAGS: select BOOT
    – APPLY, RESTART, take out the 2GB usb.
    – Boot in Win as usual.
    – This is the moment You follow STEP 2 and STEP 3 from this article.

    You should have Your Win7//Vista ready on your USB ;)

    Hope this settles it.. it did for me though..

  • Patanjali

    VistaGuyRay in the 'Boot to Command Prompt?' thread at Microsoft TechNet indicated that pressing Shift + F10 at the Install Windows opens a Command window.

    There you can use diskpart.exe to create and format custom partitions, like with 64kB sectors and align of 64, for non-removable or non-SATA SSDs in laptops like the Vaio P or netbooks.

    • Patanjali

      Just to clarify this.

      You make the USB Key, and when you boot from that and get the Install Windows dialog, press Shift + F10 to do your custom stuff.

      Press F2 at boot up on a Sony Vaio P to get to the BIOS (H2) to change Boot order.

      • Strange thing, i prepared external usb hard drive with W7, but trying to boot on VAIO P from External Device cause me an "Missing operating system" message. The same time, my desktop boots from this USB drive successfully.
        Any ideas?

        • Patanjali

          Did you change the boot order in the BIOS. Press F2 during bootup.

          You can even run Win 7 with Aero, but just need to disable some things in the Visual Effects panel of the Performance Options dialog box (Computer > Properties > Performance Information anf Tools > Adjust Visual Effects), like 'Animate windows when minimising and maximising', 'Slide open combo boxes' and any other CPU-intensive visual effects, OR just select the Bsic theme.

          The only drivers that need to be installed are the video, which you can download from the Sony P series sites. Just DON'T install any of the sony stuff as they are real resource hogs.

    Hi. Awesome post!

    Do you know how to create a bootable USB drive that will boot to a command prompt like bootable floppies used to?

    I ask b/c as part of the instructions to update my BIOS here:

    (click the how to update icon)

    it says to create a bootable system USB drive, then assumes after booting you'll be at an a: prompt (like when one used to boot from a floppy in the old days :) ).

    Trouble is when I boot with the USB drive I created with your help, Windows starts and tries to re-install itself.

  • chad

    Your instructions are a little misleading in step # 4:

    I assume you Replace the number "1" ONLY in the 'select disk' command… but partition 1 is assumed to be used no matter what the disk is numbered:

    4.Format the drive by typing the next instructions into the same window. Replace the number “1” with the number of your disk below.
    select disk 1
    create partition primary
    select partition 1

    • Professor Plum


      When you use 'create partition primary' it will create a single partition on the SELECTED device utilising the maximum useable space available. That partition will always be partition number 1.

    Please help !!! Here what I have done:
    1.Download Windows 7 iso file,which I put it in isoBuster and extracted.
    2.Coz I have listen it is better to make clean instalation,I bought new WD external HDD-Passport Studio 500 Gb and put it all information from my PC to HDD (around 90Gb very important data + windows 7 of course)!
    3.I run "cmd" and get in DOS
    – "diskpart"
    – "list disk”
    – select disk 1
    – clean…
    After i wrote "clean",I discconect usb cable,coz I afraid-what does "clean" means!!??
    For god sake-i have all informations from last 6 years on my external hard disk…

    Now,my WD doesn`t work,everything is ok in "drive manager",when i conecct usb cable there is the external usb hard drive showed up on the Safely Remove Hardware list right down,but I can not enter into the disk-inside and I am so affraid and desperate and don`t know what to do…
    How you can see,I am bigginer,but please tell me what is the best solution for me to do now and to don`t lose my data on WD (if i already didn`t lost :(
    Please,please help-with days I don`t know what to do….
    My e-mail is via_makedonia yahoo dot com
    What I have tried:
    coneccting my WD with 3 dieferent cables-usb and firewire in dieferent ports.
    installing drivers from wd site

    When I check Device Manager it shows that the device is installed and working properly but it will not show in "my computer" and I can't access it.
    before the problem,my HDD appeard as drive H:
    I wouldn't be half as frustrated if it hadn't been working properly before this.Plus-ALL data is on my HDD,and I don`t even know if it is still there :(

    I do it this:
    2 Step Solution for XP users:
    Part 1:
    Go to
    Control panel -> Performance and Maintenance (cannot be in classic view to see this link) -> Administrator Tools -> Services -> Universal Plug and Play
    If Universal Plug and Play is set to manual switch to automatic.
    Part 2
    Double Click Safely Remove icon on the bottom right-> Select device->click Properties -> click Volumes -> click Populate -> hit OK -> if nothing shows it may need to be formatted

    Also i was in DISK MANAGEMENT,but except formating disk,I don`t see solution :(
    And formating will erase all data on the disk,isn`t it?! (if i have it,of course).
    again nothing :( :(

    Thanks in advance !!!!!!

  • Patanjali

    You may have zapped your WD HD. That is, deleted the partition, which is why the drive is listed but you cannot go to it.

    This may be because you may not have changed the '1' in 'select disk 1' to that of your USB key, as stated in the instructions.

    Isn't there still the ORIGINAL of your data on the internal drive in your computer as you have NOT installed anything as yet?

    As you are a beginner, I would STOP TRYING to do anything about it yourself and take the drive to a DATA RECOVERY SHOP. It may possible to recover the contents as the data may all be still there but the partition markers have been deleted.

    • Vlatko

      Unfortunatly NO :
      I put it all information from my PC to HDD (around 90Gb very important data),because I want to do clean installation from XP to windows 7 :(
      It will be everything ok if I re-install Windows xp ?!(I have bootable XP disk)
      Or if I repair Windows XP through installation process?
      Do I have problem with MBR ?
      Should I format my WD ?
      Common,I am sure that there must be way to solve the problem with my external disk to open my data or if the disk is empty to return/recover the data somehow!
      Thanks in advance again and also thanks for the advice you gave me in second post !!!!!!

      • Patanjali

        Just to be double sure: You deleted the data in your computer after copying it to the WD?

        If so, I will not mince my words here!

        If the data is really that important to you, DO NOT risk it any more by trying advice out. You may put it more at risk.

        It may be costly to get data recovery professional to do it, but they will have the opportunity to check the current status of the data using specialised equipment and software and advise you of the chances of recovery. Something that you or we cannot really do now. No more playing around, pay the money and learn from your mistake.

  • Patanjali

    As a beginner, you should:

    – NOT attempt such processes as you are working at a very low level where mistakes can be costly. If you do not understand the consequences of each step, do NOT do them.

    – Read instructions CAREFULLY – again, if you do not understand, do NOT even start to do them.

    – If doing any such critical activities, keep a COPY of all your data on a drive that is DISCONNECTED from your computer at that time.

    – Follow the rule:
    Data is not safe unless it is on two different devices, preferably three with one elsewhere.
    Once the internal drive was reformatted, you would have had only ONE copy of your DATA anyway – this is not safe for critical data.

  • Downloaded Windows 7 .iso off the net and want to install from USB key on old laptop (previously/still running XP) that has no CD/DVD drive. Here's what I've got so far:

    * Read the instructions in this post: http://kmwoley.com/blog/?p=345 , which were quite straight forward and clear.
    * Properly formatted USB key with another laptop (this one running vista), also with no DVD drive
    * wasn't sure how to make the USB bootable, since my .iso was downloaded and I have no DVD drive.

    Any help would be much appreciated!!



    • Patanjali

      If you followed the instructions properly, the USB will be bootable, but you need to extract the files from the .iso file to the USB to use it to install from.

      Undisker is supposedly a utility that can do it.

      However, if you know someone that has Win 7 and a DVD burner, get them to Open the .iso file and select the burn disk option. You will at least have a Install disk for the future.

    From what I have learned, you need Vista Ultimate to do the diskpart thing properly (Home Premium won’t cut it), and do it from the same type of OS, i.e. 32bit for creating a 32bit bootable drive and 64bit for creating a 64bit bootable drive.

    to kevin, i never tought ufd can do so far. you're a genius.

  • Professor Plum

    Most of it has already been said. The use of 'Clean' in DiskPart just removes the partitioning information, the data is all still there. If you have an older copy of Norton Utilities (Such as version 4.5) you will be able to recover the disk by resetting the partition information values without adversly affecting the data stored.

    There are other methods to recover and restore the partition information however this is NOT the same as creating a new partition. If you are not experienced at recovering disks and data the safest plan is to do as suggested and find someone who is. It is a simple matter to correct IF you know what you are doing.

    It is vitally important (as I am sure you are now aware) to be 100% certain that you have selected/mounted the right device, the right volume and the right partition before using any of the other available commands in DiskPart.

    Once you get past the first part of the installation it will say it needs to restart. Take out your thumbdrive right when it restarts.

    I have Dell Studio15 but the problem was it's DVD writer is not working so there was no option for me to install Windows7 on my laptop the only thing i could do is make copy of Windos7 installation DVD through USB, or LAN (as i dont have a 4gb+ pen drive), So i copied the files to my HDD through LAN.

    After That the surprising thing how to do it ,

    1. i could simple click on the setup.exe but it will upgrade the current OS or make a copy to a folder and install the new os, so your going to lose around 10GB of spaces.

    2. But if you want to install a fresh copy of Windows7 , you wont be able to do it . so here is the trick …

    Restart Your PC or Laptop press F8 soon it'll take you to repair screen….after that Wola
    you got the cmd screen…..now just type command and go to the Copied Folder(Windows7)…and type setup.exe.

    haha…..Rest you know what to do…….

    I tried it and its works for me………:)

  • Joris

    I can get through step 1 and step 2. Step 3 is where I am having problems. If I try to copy all the files to the USB from the DVD there are files I need to skip and then only about 200 MB gets copied. Half of the time windows explorer crashes while I'm doing it. If I use the xcopy method via the command prompt I also get errors. Could you describe the process of copying the files in more detail? Trying to to copy files from a Windows 7 upgrade ISO. Was able to burn a DVD but I get "a required cd/dvd drive device driver is missing" error, so I am trying to install without the dvd drive.

  • Cathy

    Thanks for your site Kevin. My question is slightly off topic. I want to clone my Windows 7 Enterprise VLK installation with ImageX. I need to make my USB flash drive bootable to boot into WinPE. I created my winpe.iso. I followed your steps successfully down to the bootsect command. I copied my winpe.iso file to the flash drive. When I reboot to the flash drive, I get the error BOOTMGR is missing. What am I doing wrong?

    • Good question. It's hard to say, but it sounds like the WinPE image didn't have the expected boot manager (bootmgr). This isn't something I've tried, so let me know if you figure out what was missing.

      • Hi Kevin- Now that the holiday is past, I got back to working on this. Turns out that I was making the process more difficult than it needed to be. The creation of the WinPE adds in all of the files necessary to make it bootable. All I had to do was burn to disk. Doh! Thanks again for your work!

  • Truman

    Alright – I admit… I could be retarded; However, that prefaced, is this to simply INSTALL Win7 or Vista via the USB drive? If so, cool enough.. but if its to actually RUN Win7 from the USB drive, I must be missing a step.. Can you just confirm what my expectations should be of the two mentioned? Thanks..

    As someone else said in this thread…

I was getting a repeated "bootmgr not found" message preventing me from loading Windows 7, and the repair option on the Windows installation DVD failed to fix it because it couldn't access the hard drive – but by creating a bootable USB stick and running repair again, I fixed the problem in seconds. Many thanks!

    Excellent write up.

    I tried installing Windows 7 x64 Ultimate, it finished copying files and installing them, then Setup had to restart. After re-starting, the computer booted the USB from the beginning again. IE. It didn't leave off where it was before restarting.

    Anyone know how to get around this? I need to continue the setup process, not have the USB boot from scratch again.


  • Doc Hammer

    boot from your HD

    • cfx_66

      I realized shortly after I wrote this that the files should already be on the HDD. Thanks for the reply.

  • wolfman2

    It works another way – i copied all the WIN7 data on a stick and followed your procedure
    by using the win 7 files ON the stick

    ++++++You wrote
    # Insert your Windows Vista / 7 DVD into your drive.

    +++++I did
    you dont have to do that – just go to your stick with all win 7 files on it

    +++++You wrote
    # Change directory to the DVD’s boot directory where bootsect lives:

    +++++ I did
    Change directory to the stick with win 7 files on it

    cd x:boot (x is your stick)

    +++++You wrote
    # Use bootsect to set the USB as a bootable NTFS drive prepared for a Vista/7 image. I’m assuming that your USB flash drive has been labeled disk G: by the computer:
    bootsect /nt60 g:

    +++++I did
    use bootsec on the stick to set the same stick bootable
    I’m assuming that your USB flash drive has been labeled disk X: by the computer:
    bootsect /nt60 x:

    So you are using the programm "bootsect" from your stick to make the very same stick bootable

    Worked like a charm :-)

    If you don't know how to kick your PC over to BIOS, if the screen changes too quickly, or if it's hidden the simplest and easiest way that works with almost every computer is to press a bunch of keys on the keyboard during startup and hold it. This will produce an error message during startup and take you straight to the BIOS. This technique hasn't failed me yet.

  • Grujee

    Hi everyone, just one quick tip for all those who are interested in installing any windows (XP, Vista and Windows 7) on their machines using a USB bootable disk. There is a small free downloadable utility called WintoFlash (http://wintoflash.com/home/en/) which you can use to transfer the contents of a OS disk to a USB and then you can boot from USB to continue installation. I hope that would help several people.


  • Sandman

    Nice tutorial and thank you for sharing it. However I encountered an error that told me to format the disk during the process. I let the process finished and then I went back to that other little window and pressed format which took me to the normal windows formatting steps. Once I chose quick format and press enter it gave an error and told me that windows couldn't format the usb and i had to check systems log. I don't know what that means and would appreciate the help.

    Hey everyone, I don't know if i did anything wrong, but it said everything i did was successful. When you say "bootable" do you mean that it is like a computer where it ACTUALLY boots to the login screen or desktop? Or do you mean "bootable" meaning you can install windows 7 from it? Cause it would be really nice if i could ACTUALLY boot from it and use it like a portable operating system. When I change the BIOS and stuff, then restart the computer, all it does is want me to install windows 7. Is this right? I really don't know, but if anyone can help me out here and let me know how to ACTUALLY boot up from a USB Flash Drive, then it would help me a lot! Just email me a link on how to do it or just give me instructions. Thanks!!!

  • gump

    Forgot to mention that you need to make sure that you remove the flash drive when the computer restarts for the first time during installation (windows 7) otherwise the computer will boot up again from the flash drive and you will need to start from scratch. Also, dont forget to change the bios boot order after you are done!

    I went through all the steps w/o any problems and created a bootable Flash disk. (I had used the same instructions successfully before, when I went from VISTA to a Beta version of Windows 7.) Now, I'm going from the BETA Windows 7 to the full retail version. But, weird, when I go to reboot, it always goes right to the hard drive. I've checked the Boot Device Priority settings in BIOS, and everything is OK there. I have also tried removing the HDD from the boot device list, but then the computer refuses to boot at all. If I hit the ESC key repeatedly during BIOS POST, I get a list of boot devices, including the flash drive. I can then select the flash drive and it takes me right into Windows 7 setup (i.e., "copying files" msg), bypassing the Windows 7 installation screen. And, I need that since I need to run the utility for creating a new partition and formatting it. Would appreciate some help please!

    Made sure to fire up the command prompt using "Run as administer" in all cases.

    Then tried installing Win 7 from my desktop. While that "worked", the system parameters for my desktop are quite different from the laptop. After attaching the hard drive back into the laptop, it started groovin', but came up with a new barrel of problems.

  • Doing a full format of my 8GB USB drive took about 20 minutes.

    format fs=NTFS label="win_inst" quick

    I have Windows Vista Home Premium 32-bit and am trying to install Windows 7 Professional 32-bit but when it comes to 'Launch Instal' I get an error message to say it cannot open .img files. I have tried downloading software to open .img files but still get error messages to say they cannot be opened. Any suggestions?
