Step 1: Format the DriveThe 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.]
- Plug in your USB Flash Drive
- Open a command prompt as administrator (Right click on Start > All Programs > Accessories > Command Prompt and select “Run as administrator”
- Find the drive number of your USB Drive by typing the following into the Command Prompt window:
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.
- 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
exitWhen that is done you’ll have a formatted USB flash drive ready to be made bootable.
- Insert your Windows Vista / 7 DVD into your drive.
- Change directory to the DVD’s boot directory where bootsect lives:
- 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:
- You can now close the command prompt window, we’re done here.
Step 4: Set your BIOS to boot from USBThis 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.
