I'm having a problem booting my system. Suddenly My HD isn't detected during the boot process from my BIOS. Is ee's all other IDE devices I have installed such as CDRW ,CD This is something that has happened suddenly, I haven't added any new software or hardware to my system. I've tried changing cabling for the HD that doesn't help. I tried installing my HD in another system and it boots up with know problem. Is it possible that my BIOS is corrupted somehow?
