How To Check If The Disk Is GPT Or MBR

Basically, there are a couple of types of partition styles that can be used on your computer's hard disk, the first being "MBR" (Master Boot Record), and the second Is named "GPT" (GUID Partition Table). When setting up a new hard disk on your Windows OS, you'll be prompted whether to use MBR or GPT, hence having prior knowledge Is paramount. In this tutorial, I will show you how to check If the hard disk Is using the MBR or GPT partition style.

This not only relates to Windows 10, but also prior versions, namely Windows Vista, Windows 7 and Windows 8. Depending on your system and overall usability, each have their pros and cons, thus from an end user's standpoint, there's no right or wrong as to which of the two Is advantageous. For example, Windows can only boot from GPT on UEFI-based PCs that're running the 64 bit architecture of Windows 10, 8, 7 and Vista. If your computer and OS does not meet this requirement, you cannot use the GPT partition style to boot.

The MBR partition style on the other hand, Is used with 32 bit computers, as well as removable drives such as memory cards and USB sticks. It's beyond the scope of this article to cover every detail pertaining to MBR & GPT, so I'll leave It at that.

To check If your disk Is MBR or GPT, I will be using the Windows built-In utilities named Diskpart and PowerShell. So without further delay, let's get this tutorial started.

Step One:
Firstly, I will be using Diskpart by opening the Search bar, entering diskpart and clicking on the entry at the top as arrowed.

Step Two:
Diskpart will now execute, so type list disk and hit Enter. As you can see, the partition style on both my hard disks, Is GPT.

Step Three:
Let's do the same, but this time using PowerShell, which must be executed with elevated privileges. Open the Search bar, enter powershell and at the top, right-click the search result and click on Run as administrator. 

Step Four:
Now enter get-disk as Illustrated below, and hit the Enter key on your keyboard.

Last Step:
As you can see, my hard disks on my computer are using the GPT partition style.

Final Thoughts:
If you've read the opening paragraphs thoroughly, you're now well aware of the GPT and MBR basic structure. It's very Important to know what partition style a particular disk Is running, namely when first setting It up on your PC. You can now obtain the details with Incredible ease. Do remember, that you must run PowerShell with administrator privileges.
