I have tried to reboot it in all modes and last useable point. Nothing helped. It is almost like a boot loop. It dumps memory then reboots to safe mode page and starts over again at the blue screen. I have tried to repair using the windows cd selecting the "enter" not the "r"but after the F8 agreement page I didn't get the screen about the repairs. It said something about partitions and I was afraid to continue. What do I need to do to fix the registry thing?
