This error indicates a corrupt registry. Luckily, when Windows is installed, a pristine copy of the registry hives is also installed and it remains untouched...replacing your corrupt registry hives with these ones will allow you to boot your operating system again. You may have to reinstall a few programs and drivers but all of your data will remain intact and you really won't lose anything. I will describe the process to you. I will also include instructions on how to back up the current registry in case you want to go back to it for any reason.

First you will need to locate the Windows install disc. If you don't have one you can borrow one as you will not need a key to perform the steps.

Put in the disc and perform the steps necessary to get your computer to boot to it.

Once you are the "Welcome to Setup" screen, press R to go into the Recovery Console.

Enter the administrator password when prompted

Tell the program what installation of Windows you would like to recover.

Now for the commands

md tmp (this creates a directory labeled tmp)

These 5 commands will make a copy of your current registry hives and back them up to the tmp directory. Type these in first. ENSURE you back them all up.

copy c:\windows\system32\config\system c:\windows\tmp\system.bak
copy c:\windows\system32\config\software c:\windows\tmp\software.bak
copy c:\windows\system32\config\sam c:\windows\tmp\sam.bak
copy c:\windows\system32\config\security c:\windows\tmp\security.bak
copy c:\windows\system32\config\default c:\windows\tmp\default.bak

These 5 commands will delete the current, corrupt registry hives.

delete c:\windows\system32\config\system
delete c:\windows\system32\config\software
delete c:\windows\system32\config\sam
delete c:\windows\system32\config\security
delete c:\windows\system32\config\default

These 5 commands will copy the pristine, uncorrupted hives into your system.

copy c:\windows\repair\system c:\windows\system32\config\system
copy c:\windows\repair\software c:\windows\system32\config\software
copy c:\windows\repair\sam c:\windows\system32\config\sam
copy c:\windows\repair\security c:\windows\system32\config\security
copy c:\windows\repair\default c:\windows\system32\config\default

Once you have entered your last command type exit to leave the recovery console and your computer should restart.

If you want to put the old registry back for any reason, simply follow the same steps but instead delete the current registry and replace it with the files that you placed in the tmp directory. Ensure that you remove the .bak extension from the file when you copy them over.

Really, other than this, the only other known working option is to reformat your computer.

Hope this helps.
