Install Windows Vista from a USB 2.0 Flash Drive

Connect the USB flash drive and make sure that you know its address. In order to find this out, just type “list disk” after you run CMD.exe. The USB flash drive will have an address like this “disk 1”, but we will continue to refer to it as “disc x” where “x” is the number of the drive on your computer. You will now need to enter the following commands: 1. diskpart
2. select disk 1
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exitUsing “xcopy d:*.* /s/e/f e:”, simply copy the entire content of the Windows Vista DVD on the flash drive. Boot the computer from the USB drive and simply install Windows Vista.
NOW you can try another command also, instead of 9th step try the following.

Make It Bootable!

The format step may take a little while (it actually took about 30 minutes on my machine). When you’re done, put in your installation DVD if you haven’t already. Note down which drive letter your USB disk and Windows installation DVD are located at.

Go back to your command prompt and type – assuming D: is your DVD drive with the install DVD, and U: is your USB drive:


This will basically make your USB drive bootable.

Copy Everything

The final step can be done from My Computer. Just open up the installation DVD, highlight everything, and drag it over to your USB drive.

This will also take a while.

Now you should be all set – just insert the USB disk into your new PC, and enter the BIOS to adjust the boot order, or choose the option during start up which says Choose Boot Device.

There is another option to create bootable USB pen drive from ISO image.

To ‘burn’ an ISO image to the USB flash drive, follow these instructions:

  1. Install it as you would any other application.
  2. Load UNetbootin from your start menu.
  3. Select the Disk Image (second option down).
  4. Select ISO from the drop down.
  5. Click the three periods to browse for an ISO image.
  6. Make sure the Type is set to USB drive and the letter corresponds correctly.
  7. Click OK.
  8. The process will take a while, so grab a cup of tea!
