When I boot my computer I end up with a blank blue screen & a movable cursor. Same thing in safe mode. I boot from the Vista 64 recovery disk & go to repair option. There is no operating system listed to repair. It asks to load drivers, but I have no idea where I might find them. Can someone help me get past this point on the recovery disk. The computer is an HP Pavilion with an AMD Quad core processor runing windows 64, 6gb of ram, 200 gb hard drive. Thank you in advance for your help!!
