Default Behavior

The Volume Manager Driver service is a kernel device driver. In Windows 8 it is being loaded by Boot Loader before Kernel initialization. If Volume Manager Driver fails to load or initialize, the error details should be automatically logged. Then Windows 8 is restarting the PC and attempting to use the Last Known Good configuration. If the Last Known Good configuration isn't working properly, Windows 8 startup ends with a Stop error. If you disable the volmgr service, Windows 8 will fail to start.

Restore Default Startup Configuration for Volume Manager Driver

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config volmgr start= boot
sc start volmgr

3. Close the command window and restart the computer.

The volmgr service is using the volmgr.sys file that is located in the %WinDir%\System32\drivers folder. If the file is corrupted or deleted, you can put it back in there.
