Friend's Dell desktop, running XP Home, stopped working. Tried a Repair Install, but the Windows installation was so corrupted that Setup wouldn't see it. So I put in a new hard drive and started a full Install. Everything goes along until the point where Setup reboots the PC, and then normally the GUI part of the setup would start. Instead, the entire setup starts over again After this happened twice, I even reformatted the hard drive and tried again, but the same thing happened. Any idea what might be wrong?
