MBR (Master Boot Record) and GPT (GUID Partition Table) are two partition styles of computer’s hard disk. You may not quite know what partition style your disk is formatted in. Now in this post we will show you four different ways you can check if a disk uses MBR or GPT partition in Windows 10.

Way 1: Check if a disk uses MBR or GPT in Disk Management

Step 1: Open the Disk Management in Windows 10, by pressing Win + X and then selecting Disk Management.

Select Disk Management

Step 2: In the Disk Management window, select the disk you want to check, right click on it and select Properties from the context menu.

Select Properties

Step 3: The disk’s properties window opens. Select the Volumes tab, under which it shows if the disk’s partition style is MBR or GPT.

Way 2: Check if a disk uses MBR or GPT in Device Manager

Step 1: Open the Device Manager in Windows 10, by pressing Win + X and then selecting Device Manager.

Step 2: Expand Disk drives, and then double click the disk drive you want to check.

Step 3: After the disk’s properties window opens, select the Volumes tab, and then click the Populate button.

Step 4: Now under the Volumes tab you can check if the disk is using MBR or GPT partition style.

Way 3: Check if a disk uses MBR or GPT with Command Prompt

Step 1: Open an Administrator Command Prompt, by pressing Win + X and then selecting Command Prompt (Admin).

Step 2: In the Command Prompt window, first type in diskpart and press Enter. Next, type in list disk and press Enter. So it list all the disks currently connected to your computer, and their respective properties. Look to see if a disk has a *(asterisk) in its GPT column or not. If a disk has a * in its GPT column, the disk is GPT partition style. If a disk does not have a * in its GPT column, then it uses MBR partition style. As you can see, in my example, the disk 0 does not have a * in its GPT column, so it is using MBR partition style.

Way 4: Check if a disk uses MBR or GPT in Windows PowerShell

Step 1: Open a Windows PowerShell, through searching powershell in Start menu Search.

Step 2: In the Windows PowerShell, type in Get-Disk and press Enter. So you can look to see if a disk uses MBR or GPT in the “Partition Style” column.
