How to boot/install Windows 7/Vista from USB Flash/Hard Drive

Hi
(To Diego Ferrer, who told me about to write something more often).

I always search for this procedure.

Click Start –> type CMD and right click Run as Admin
- Inside cmd, type and enter the followings:
diskpart
type “list disk” and you will see all connected disks and numbers

select disk X (X being the number of the usb disk )
clean
create partition primary
select partition 1
active
format fs=fat32
assign
exit
