After reinstalling XP,which solved many problems, I can not boot up without my XP disk. When I try, I just get a insert disk and hit any key command. I have tried to find a way to boot from hard drive in normal mode but can't. Every inquiry to knowledge base has not addressed this issue. Any ideas or fixes. Also my num lock turns off each time I boot or log on which is a pain if anyone can tell me how to stop this. I have never encountered these problems through 3 operating systems and am baffled.
