Inaccessible boot device on Windows 2012 with EMC Networker

I would like to share my experience related to the above error.

Recently we received a call from our customer saying that 2 VM’s were not booting. We were in panic mode as these 2 servers are the domain controllers and the backup software which was supposed to do the BMR also failing.

Thereafter when we contacted Microsoft Support the team identified the error is due to the “nsrbbwi” key which being added on the Registry by our EMC Networker Backup Tool and once it was removed the servers booted normally.

Go to the below Registry via the Command Prompt from the System Recovery Options

ControlSet001\Control\Class\{533C5B84-EC70-11D2-9505-00C04F79DEAF}

ControlSet001\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F

Remove the Value for “Upperfilters” as it will be pointed to “nsrbbwi”

Reboot the server.
