Oh okay, so i have to get another windows 7 ultimate. If i get another one, do i have to get a windows 7 home premium x64, then get a windows 7 ultimate to keep all my stuff. I wouln't mind losing all my stuff, but i want the nVidia software installed in my computer. I'd use a cd for the nVidia software, but the software is from my factory default recovery disc and i don't think you could just install the nVidia software without having to install the rest of the factory default software.
