Windows 2000 - "c:windows\system32\config\" missing or corrupted

I had a problem on a very old Windows 2010 server and I got precedent error and no boot way was available:

"c:windows\system32\config\" missing or corrupted

I tried several procedures:

  1. Last configuratioin restore
  2. Windows recovery mode.
  3. Boot from Server CD and going on recovery console and running Chkdsk command

The only solution was to follow this microsoft article:


I am focusing on more important commands used:

cd system32\config
ren system system.old
ren system.alt systemalt.old

To copy the default System hive, type the following command, and then press ENTER:

copy c:\winnt\repair\system c:\winnt\system32\config

To copy the System hive that was backed up the last time that you ran the Emergency Repair Disk Wizard, type the following command, and then press ENTER:

copy c:\winnt\repair\regback\system c:\winnt\system32\config

In my case there was c:\winnt\repair\system.bak file that I copied with this command:

copy c:\winnt\repair\system.bak c:\winnt\system32\config
