I got a new hard drive so I tried to put the old hard drive in one of my other computers. I know it's usually not good to do that since the motherboard is different and everything, but I didn't want to have to reformat. Anyway, the problem is that the computer is stuck in a continuous boot cycle. It will get through the BIOS checks and will reboot just before windows starts. I put in the Windows XP cd and it comes up with the boot from cd prompt. As soon as I hit a button to boot from the cd, it will reboot like before. I slaved it in to my good computer and copied most of the important stuff that I need (just in case reformatting is the only option). Is there any way to stop the endless reboots?
