When you forget to setup UEFI on a new server!

  • Fear not. Just grab mbr2gpt.exe from the \windows\system32 folder on a windows 10 machine and drop it anywhere you want on the new server, then run:

    mbr2gpt /convert /disk:X /allowfullos

    and you will be ready to restart and set your bios to UEFI support and finishing booting to your new uefi partition!
