Dell Precision 650 server running Windows 7 x32. Few weeks back it refused to start. On power up it goes straight into launching windows start up repair. It does its thing and at the end the diagnostic says overall that it does not know what the problem is . I've tried Command prompt and . bootrec / mbr and bootrec / fixboot . All have returned with completed successfully ...but PC still wont boot. chkdsk /r is unable to carry out its test as a window says the drive is locked. I am not losing my data. This is a fixable problem with no loss to my data so I would like to know how to go about it. My registry may be corrupted and I never had any earlier restore points made.
What are any additional solutions to get this PC to boot?
