did you have to buy it agaim?
No ... I literally downloaded the wintoflash software ... stuck my win7 install cd in my winxp pc ... plugged in the usb ... started wintoflash and indicated which drive the cd and usb were and walked away. When I came back I pulled off the usb and used it to load my new win7 pc.
Installing win7 from a usb to a ssd is pretty fast, compared to the old way!
