Trying to resurrect my outdated Presario. I don't know if the CD drive is bad, but the Hard Drive went bad and I got a new (used) one, however the drive wont be detected on my operational computer when connected. Is this drive probably bad too? I can't get to the BIOS on the old Presario because I hear you need a boot partition for a compaq, which that Hard drive is gone and it doesn't look like I can get anything on this one. Should I admit defeat, or do you have any Ideas?
