Be sure your bios settings haven't been reset. Also check your sata setting in the bios. It should remain the same as when you first installed windows, either native ide or achi. Same for the boot order (cd>hardrive, etc). Disable all floppy settings unless you use one.
well, I didnt install my OS yet It was a test boot and I thought something is wrong there but it's fine now, apart from that strange CPU cooler start-up. Is it happening to your coolers as well tho or just my is weirdo?
