Answer

To solve “BOOTMGR is missing Press Ctrl+Alt+Del to restart” error we should follow by procedure:

  1. Boot server from installation media,
  2. Go to Recovery Console to open Command Line window,
  3. Start Diskpart by typing… 🙂 Diskpart,
  4. Now we need to list disks and select proper one where Windows is on by typing: List Disk and Select Disk X where X is correct number,
  5. Do the same for volume. Use List Volume and Select Volume X, where X is a number of volume where Windows is installed on,
  6. Last thing is to type active to mark volume with Windows installation as active.
