Hey everyone, I have a dell computer there that has the C:\WINDOWS\SYSTEM32\CONFIG\SYSTEM file missing or it is corrupt, when I boot. This article from MS http://support.microsoft.com/default.aspx?...b;EN-US;q307545 tells how to fix it, but I have another hurdle to get by before I can even do that. If I boot from the XP cd and go to the recovery console to do those steps in the article, I get a BSOD that mentions "Registry_Error 0x00000051" and therefore no matter what I do to try to get to console it gives me that error. Any ideas on how to fix it?

Thanks,
Kickehy

Catch 22. There is a fix but it had to be downloaded and installed before receiving this error. Was your computer fully updated?

The best bet now is to slave your hard drive in another computer or boot with a Knoppix Live CD to retrieve and save your data and do a reinstall of the OS.

I highly doubt it was fully updated. This is a friends computer that he just gave me to fix. So, I have no idea what he did to it before hand, but I assume it wasn't updated. That's what I was hoping not to do, but looks like that's what I'll have to do :/

That's the biggest problem with some systems is the owners don't update them to avoid these issues.

You "may" be able to fix this error by:
1) Booting to a Preinstall Environment (with a Bart PE disk) DO NOT let it load the registry hives!
2) Rename the registry hive files in the %systemroot%\Windows\system32\config directory (I just add .BAK to each)
3) Navigate to System Volume Information, locate the restore points and drill down to the SNAPSHOT sub-directory.
4) Copy the Local Machine registry hive files from there to the %systemroot%\Windows\system32\config directory
5) Rename the copied files to the names of the files that were originally there (SAM, software, system, etc).
6) Try to reboot into Windows. If it doesn't work, go back and try it with another restore point.
7) Restoring the original files that you renamed will return the system to the state it was in before you started this.

It works often enough to try it - but not often enough to consider it to be a fix for everything.

Good luck!
