LAST KNOWN GOOD CONFIGURATION as noted at http://support.microsoft.com/kb/307852
I recently deleted some registry entries (following instructions listed on HP's website in order to remove their software), now my computer "sees" my harddrive but it says it needs formatting (i.e., I can't access it all, neither as the boot, or as a slave).
I don't recall the exact registry entries I deleted (had to do with "installation"). there were 3 I deleted, (and yes I backed up my registry). At first I rebooted saw something was wrong, and thus tried to restore the registry copies but got an error stating that the files were in use. i kept trying and suddenly my computer stopped booting up all together. I have norton systemworks on it so when I insert the boot disc, it shows my drive, but it says it needs formatting (i can't see any files in it). I know that my hard drive is not the problem, I've run chkdsk, etc. and I'm sure I caused it when I messed with the registry. I've tried setting up my drive as a slave drive (SATA), but when i click on it, I get the same message stating that the drives requires formatting. I can't run windows repair either. Can anyone please help!?
I do have an acronis image backup of the drive that is ~6mos old, if it were possible to reinstall/fix the registry without booting up, I could possibly restore the backup image onto a different hard drive, extract a copy of the registry and then try to reload it to the troubled drive, but 1) I don't know of such software, and 2) I don't know for sure that this solution would work.
i'm running windows xp (latest service pack). I hope someone can please help, thanks so much in advance!
