Due to being raped by viruses, I went out and bought a new computer. I used my old virus-ridden hard drive in the new computer and cleaned it up with norton anti-virus. I was using it as a back-up drive, but then decided I would like to put it into my old computer and sell it. So I popped in the recovery disc, selected "full system recovery". Some sort of error happened, so I rebooted, and it said "No OS detected, press 'r' for full system recovery" So I did, then I keep getting a blue screen saying "Check for viruses. Check HD for proper configuration, Run CHKDSK/F, scan for HD corruption, Tech info: STOP 0x0000007B (0xF7948640 0xC0000034 0x00000000 0x00000000" Any ideas?
