  Compaq presario cq57-339WM does not recognize the drive as a boot drive recovery, I'm sorry people, I searched and I entered the job in New York as a matter of research. Operating system is 7 Home premium. Hard drive went bad, so I rplaced with new. I have had I have windows image backup, but the wizard could not find the hard drive. I ordered the HP poped the first of the two recovery disks, but the machine does not recognize the drive as a bootable disk recovery. I did factory retrieve records a large number of times on computers with different operating systems and have never seen this. TNA
