MS boot MGR missing issue

-
Bootmgr was missing.

Booted in WinPE and started startrep.exe from X:/sources/recovery.

The server repaired up files and rebooted the server but no help.

Booted again in WinPE mode.

Checked and found that bcd file was corrupt.

Rebuild boot files.

Checked the active partition using diskpart and found that the active partition was not system reserved.

Marked active partition as System reserved which was F drive.

Rebuild the boot files using C:\windows\System32\config>bcdboot C:\Windows /s F:

Checked with bcdedit if the bcdedit was pointing correctly.

Rebooted the server , but the server got 7B error.

Booted the server in safe mode but no help.

Booted the server in last know good configuration but no help.

Changed the controller type to paravirtual as the server was initially configured.
Booted the server again.

Server booted up fine and came to login prompt.
