Recovery of windows registry, windows system32/config, or corrupt hive file errors.

Don't forget to listen to your computer to see if it has the "Clunk of death" in the hard drive before starting any windows repairs.

Recovering from a corrupt hive, windows system32/config file errors or even some registry stop errors like c0000218 can be easy if you know how to get into system restore without windows being able to load. In an earlier help page I wrote about using a windows xp disk and using the recovery console to get to a very primitive but effective DOS like screen that allows the user the ability to put the files from the system restore folder into the system 32 config folder to restore the registry.

This time I am using the Bart's PE disk to do a manual system restore. I have done this several times since I like to try what I post on the site. The Bart's PE disk can be very handy and will allow you to get to your files without putting your hard drive into another machine to move the restore files. It will also take less time to load to the Bart's PE disk than getting to the XP Recovery console.

First you need to have or make a Bart's PE disk. The Bart's PE disk will give you a bootable live windows CD or DVD to boot your system with. Visit here
(this link opens a new window so you wont loose this one) to download and get instructions on how to build your Bart's PE disk.

After you create the disk you will need to make sure your system with the corrupt version of windows boots to your CD or DVD drive first. If you don't know how to do this, click here and read the first part of this previous article.

Power up the corrupt computer and put the Bart's disk in it. Hit the reset button so your computer reboots to the PE disk.

Your system should boot to what I will call the Bart's Desktop. A window will pop up asking about network support. Just cancel that. You won't be needing it for this fix.

Click on go.

Move up to programs and click
A43 File Management Utility
a window that looks a lot like windows explorer (not internet explorer) will come up and you will need to open the C: drive.
For this article we will assume your windows operating system is on the C: drive. 

Now open the folder that says System Volume Information.

You will now see a folder that says _restore{bunch of numbers and letters} open that folder.

This is your system restore folder. You should see folders that say RPxxx RP stands for Restore Point and then there will be a number next to the RP. In the system I'm working with to write this article there are only two restore points. RP 0 and RP 1 Most systems have way more than this but I just loaded windows on the test machine. Rule of thumb is to use the second to the last restore point. You can go back and use an earlier restore point if the one you choose doesn't work for you.

Open the restore point you wish to use for your recovery.

Now open the folder that says snapshot. In this folder you will find many files. the files you are interested in are




I will guess that if your this deep you know how to copy and paste. Highlight and copy

Navigate to

You will notice that there are several files named system and also several that say software. The ones we are concerned with are the ones that don't have a file extension listed after the file name.

Note: Some people say you can just change the file extension of the .bak files of system and software files that are already in the config folder, but the .bak files may be more recent than the ones in the system restore folder that you should be working from. If you choose to, you can try deleting the system and software files from the config folder and remove the .bak from the other system and software files then reboot the system remembering to remove the PE disk so your system will load to the hard drive. If this works... GREAT. If not then finish with these instructions.

Now Right click on the file that says
system and delete it. Be patient it will take a minute or two for Bart's to delete the file. If you click a spot in that window you will notice your cursor will change. When it changes back to a pointer again you should be able to go to the next step.

Paste the    
_REGISTRY_MACHINE_SYSTEM    file into the config folder and rename it SYSTEM
Again you may have to wait while the file is renamed.

Now repeat the copy and paste process with the
_REGISTRY_MACHINE_SOFTWARE    file remembering to delete the old software file before you rename _REGISTRY_MACHINE_SOFTWARE to SOFTWARE.

You should now be able to click on
Move up to
Shut Down

Make sure to get the Bart's PE disk out of the drive after the computer begins to restart, otherwise your system will boot up to the PE disk again and you will have to restart the system again to get to the windows operating system.

Once again I remind you that once you have recovered your system you need to check your drive with software that can detect a bad drive. No sense in having the thing working again and have it quit after your repair. Better to know the drive is bad and replace it than go through all this just to have the drive die and loose it all again.
