Stop error 0x00000074 – BAD_SYSTEM_CONFIG_INFO


This STOP error occurs on startup if the SYSTEM registry hive is corrupted.


Restore the SYSTEM hive from the backup that Windows automatically creates on every successful startup.


  1. Go to the Repair Console using a boot disk and open a command prompt.
  2. Go to E:\Windows\system32\config.
  3. Back up all existing registry hives.
  4. Overwrite SYSTEM with E:\Windows\system32\config\regback\SYSTEM.
  5. Reboot.


This will correct a one-time corruption of the SYSTEM registry hive, but it is possible that the system may be in a condition to cause the problem to recur the next time it is successfully started. This would require the fix to be performed on every reboot.
