July 24th, 2017 by Admin Leave a reply »

How can I determine if my disk is formatted as GPT or MBR? Since the release of Windows 8, GPT partition style is becoming a popular alternative as newer computers are shipping with UEFI firmware, and Windows 10/8 can only boot from GPT disk on UEFI-based computers. In this tutorial you’ll learn how to find out where your disk uses MBR or GPT partition style in Windows.

Method 1: Check If Your Disk Is MBR or GPT Using Disk Management Tool

  1. Press Windows key + X on your keyboard, and then select Computer Management from the pop-up menu.

Method 2: Check If Your Disk Is MBR or GPT Using Command Prompt

  1. Open the Command Prompt with administrative rights.
  2. At the Command Prompt, type following commands one by one, pressing Enter after each.
    diskpart
    list disk

    list-disk-cmd

  3. It will list all disks that are connected to your PC. If a disk uses GPT, you’ll see an asterisk character (*) under the Gpt column. As you can see in the screenshot above, disk 0 is a GPT disk while disk 1 is a MBR disk.

That’s it!
