If you would prefer to check from Ubuntu:

  1. In Ubuntu open the terminal and type "sudo parted -l".
  2. Scroll to the part with information on the disk your Windows installation is using. Under "Partition Table:" it should say gpt or msdos. GPT is required for Windows to run in UEFI mode. msdos means you're using BIOS/Legacy Mode.

  1. In Windows 8 go to the start screen
  2. Right click on "command prompt", and choose "run as administrator". [If you can't find it look under all programs.]
  3. In command prompt type "diskpart.exe".
  4. In diskpart type "list disk". It will show a * under the GPT column for disks using GPT. Windows requires GPT in order to run in UEFI mode.

Alternatively, another Windows 8 method is as follows:

  1. In Windows 8 go to the start screen
  2. Click on "command prompt" [If you can't find it look under all programs.]
  3. In command prompt type "msinfo32". Under "BIOS MODE" it should say UEFI if you are running in UEFI mode.
