I have a computer (Dell) and all of a sudden it will not boot past the "Starting Windows" screen. I have run Startup Repair from the recovery partition and a Windows 7 DVD but no improvement. I ran their diagnostics and UBCD on the drive and it passes. Then all of a sudden on one bootup it went past the "Stasrting Windows" to the balck screen with the white arrow (mouse pointer). Is there any way to get this booting up without re-installing the whole drive?
