Ok so on my system i have win xp pro. when i try to boot it fails because it the system32/config/service file is corrupt or missing. Then when i try to run repair utility off win xp pro install disk i get the blue screen right before any options come up. The bluescreen is for a HDD failure but the HDD is ok. I have ran check disk from ubcd4win and have done both short and long hdd test with seatools. Any suggestions?
