Hi When I start my computer I get a black screen with Disk Boot Failure, Insert System Disk & Press Enter. The BIOS doesn't list the harddrive, CD, or DVD drives....(The only drive listed is the floppy drive). I have checked the cables & all seem on tight. This is a hp pavilion computer (windows XP-home) it was working fine until I turned it on one morning & received a BSOD. I restarted it......Now all I get is the Disk Boot Failure & it won't load windows. Any HELP would be greatly appreciated!
