Afterward, restart the PC and check if your computer boots up normally. 

Fix 5. Restore Windows Registry

The Registry is a database that contains the configuration information of the operating system and most of the applications. When Registry corrupts, it may lead to serious problems like the Automatic Repair loop.

The good news is that the registry makes a backup of configuration data automatically. You can use the backup to restore the Windows registry to a working version.
