I have a Dell XPS M1330 running XP pro SP3. It will not longer boot. It starts and goes to a black screen saying Windows cannot start because WINDOWS/SYSTEM32/CONFIG/SYSTEM is missing or corrupt. I have tried the repair console and it doesn't see the drive even though it is in the Bios and it reads fine as an external drive hooked up to another PC. Is it possible to get this drive to boot any longer without destroying the data that is on the drive?
