Hey, I have a pretty bad problem on my hands.
My friend game me his sister's computer to fix, and I'm stumped. The BIOS posts, but doesn't recognize that any drives (HDD and optical) are connected. As a result, all that I see is a message saying "operating system not found". I tested the HDD on my PC and it worked fine. I tried booting an XP install cd and a BART PE CD, but none of them would boot (because the peripherals weren't detected). The only thing I can think of is that the IDE controller is fried. Any other thoughts?
