Install Windows 7 From a USB Flash Drive

Windows 7, I’m sure you have heard of it by now. Already Microsoft has a new operating system, hopefully this one won’t be a disaster like Vista was. If you installed Vista or even later versions of XP from a DVD you know that it was very time consuming. Why not speed up the process by using a flash drive to install Windows 7. Windows 7 is currently in beta and Microsoft is offering it free to anyone to try out until August. In this article we will show you how to take the Windows 7 ISO and put it on a USB flash drive for fast and easy installation.

Ok so the first thing you are going to want to do is get the Windows 7 ISO. Microsoft is no longer offering it from their website, but there are sure a lot of other places you can get it at. Also if you have a Windows 7 DVD this guide will work with it as well. After you have the Windows 7 ISO you need to mount either burn it to a DVD or mount it. I had the ISO already so I just decided to mount it using Daemon Tools. Once it is mounted make sure you remember the drive letter.

Next we want to prepare our flash drive. The Windows 7 ISO is about 2.5GB so you will need a flash drive at least 4GB in size. I am using an 8GB flash drive I got from BFG during CES. Once you have your flash drive plug it into your computer and also make sure you remember the drive number. Now open up command prompt and type: diskpart

This will open up a new command window. No if you are like me you have many USB drives and card readers connected so you want to list your drives so you know what drive your connected USB drive is. To do that type: list disk

This will list all of your connected drives or card reader drives. Now identify your flash drive, for us it is drive 13.

Now select the drive by typing: select disk 13 Now run the following commands…

clean
create partition primary
select partition 1
active
format fs=fat32
assign
exit

Now what we did there was create a primary partition on the flash drive, make it the active partition, and format it with the FAT32 file system. Simple enough right?

Now we have to copy the files from the Windows 7 ISO or DVD. So either put the DVD in the drive or mount the image you have. As I said before make sure you know the drive letters of your flash drive and of the DVD drive you are using. Now open command prompt back up and type in this:

xcopy j:*.* /s/e/f r:

Now in this sequence the J: drive is our mounted DVD drive and R: is our flash drive. The drive letters will vary for you of course. One you type the command in and press enter you will see all of the files being copied, just wait till it is completed and you will have a bootable Windows 7 flash drive!

There is one more thing you are going to have to do to get this to work. You are going to need to go into the BIOS of your laptop and make the first bootable device the USB drive. This was very easy to do on my Dell XPS M1210. After that you are good to go, so just plug in your flash drive and install Windows 7.

Not only is this method convenient (carrying a flash drive is better than a DVD), it is much, much faster than installing from a DVD. This guide not only works with Windows 7 but will also work for Vista as well. Hope this guide has made installing a new operating system easier, stay tuned for more Windows 7 related articles.

  5. it needs to be done with vista/seven. on xp using the list disk command i couldn't see the usb too, but when i tried on seven it worked.

  6. Sweet. I was looking around for a guide to do this again. Did it on my computer with a 32 bit OS. And needed to do the same for my Girlfriends 64 System. So this came in handy. Thanks.

  7. Unfortunately these instructions only work when running on Vista and newer operating systems. I just ran across an app that automates the process of creating a bootable Win7 flash drive, but does it under XP as well.

  8. why my 8gb cant appear if i type “listdisk” but i can see it on my computer and disk management?
    any one can help me?

  9. If you're using WinXP and below, then your diskpart will not see it. You will have to do that on Windows Vista and above. Had the same issue, but did some research and then did mine on my work laptop with Vista on it. Try it out.

  10. While the manual process has worked fine, Bootsage is nice because it bypasses the manual steps and automates the whole process. Good find!

    what sistem shell i instal to turn it on guys , i want to use this machine its pretty

  15. I have no boot menu on my laptop.
    And installation Windows 7 DVD was scratched.
    What i did was:
    1) download windows 7 installation ISO;
    2) unpack it on flash drive;
    3) boot from any installation CD/DVD (just to get close
    to command promt);
    4) format c:;
    5) copy contents of flash drive to c:;
    (xcopy f:*.* c:);
    6) reboot.
    The PC will boot from c: as it was some DVD and will actually install Windows on itself.

  16. If you installed Vista or even later versions of XP from a DVD you know that it was very time consuming. Why not speed up the process by using a flash drive to install Windows 7. Windows 7 is currently in beta and Microsoft is offering it free to anyone to try out until August.
