I have Windows XP on a laptop and it gets as far as the XP loading screen then restarts constantly. Can't get safe mode either. Booted XP disk and pressed enter to setup xp then agreed to the license. When I try to repair from here, there is no operating system. So I tried to go through the recovery console. Usually it asks what operating system to use however I didn't get that option it just went straight to the command line. I tried a chkdisc /r which scanned and repaired 1 error however it still reboots itself constantly. What other options do I have to try and get Windows back other than reformatting?
