I ran into a little problem with getting a “fresh” Windows 7 installed on to my net book. After a bit of research I found the following procedure… and it worked perfectly!!!
Without further ado… here are the Vista instructions for how you can create a bootable USB drive to install Windows 7 on your system.
1. Format USB flash drive to NTFS format
2. Disk-Part the Drive
On the Start menu, navigate to the command prompt entry. Right-click and select Run as administrator.
Record the disk number of your USB flash drive.
Select the USB disk.
select disk X (X is the drive number of the USB flash drive)
List the current partition. Record the partition number.
Select the current partition and make it active.
select partition Y (Y is the partition number of the USB flash drive)
3. Prepare the OS files
Download Windows 7 file to your desktop.
Download and install PowerISO from http://poweriso.com/.
Right-click on the Windows 7 iso file and select Extract files. Extract the files to a folder (you can name the folder any name you want, but for illustration purpose, I name it win-7) in your desktop.
In your command prompt, cd to the windows 7 folder.
cd Desktop/win-7 (Change the destination to the folder that you have extracted)
bootsect /nt60 X: (X is the drive latter of your USB drive )
Now, copy all the files from the Windows 7 folder to the USB flash drive.
Reboot the computer. Remember to change the first boot device to your USB drive in the BIOS.
You should be able to install Windows 7 from your USB flash drive now.
