Okay, so I took my computer down to a shop to have an upgrade, mostly to just clone the hard drive to a new system. When I brought it back home though and booted the old system up, it gets stuck in a windows 7 repair loop and just reboots over and over. I cannot get it to recognize the windows XP cd. I tried it on my new computer and it recognizes the CD just fine. I tried checking the CD rom connections, everything seems ok. Any help please?
