My problem is this: I first installed Vista Ultimate 64 Bit into my F: partition and then Vista Ultimate 32 Bit into my C: partition. Therefore the boot loader and all its related files are located in F: When I try to run a BIOS patcher like i.e. Vista Loader or any other patcher into my C: partition (Vista x32) then Vista x64 becomes genuine (lol). Please can someone with some skill suggest me seriously what to do once for all?
