System recovery unable to rebuild system registry

4.5

Recovery fails because the registry hives are missing or too damaged to be reconstructed.

Symptoms
  • "System Registry is missing or contains errors"
  • Blue screen: CONFIG_LIST_FAILED
  • Error 0xc0000225
Possible Causes
  • Failed update
  • Power outage during write
  • Disk corruption

Step-by-Step Fix

1

Restore from RegBack

Copy files from C:\Windows\System32\config\RegBack to the config folder.

2

Run DISM Offline

Use DISM with the /Image and /ScratchDir flags to repair the offline registry.

3

System Restore

Use an earlier restore point as it includes a backup of the registry.

When to See a Technician

Modern Windows versions (1803+) no longer automatically back up the registry to RegBack. You must rely on System Restore.
