I just bought a new hard drive for my HP s7613w computer and when I try and get it to boot to cd i get the "Disk boot failure, Insert system disk and press enter". It loads past the bios screen then goes to a black screen with flashin cursor then the error comes up. The disc drive is in higher boot priority than the hard drive, but doesnt seem to make a difference. No matter what i try it seems to always come back to this same error. I have tried to put in another hard drive as well and it seems to be doing the same thing. Could this be a bad motherboard?
