How to check if a Disk Drive is GPT or MBR in Windows 10?

If you are planning to reinstall a fresh copy of Windows 10 on your computer or laptop, you should check if the partition scheme on your device is GPT or MBR so that you can prepare the correct bootable Windows 10 USB for the installation.

You might already know that a bootable USB driver prepared for the GPT partition scheme cannot be used for installing Windows 10 on an MBR partition-style drive. Similarly, if you create a bootable USB drive with an MBR partition, it can not be installed on the GPT partition.

Before preparing a bootable USB disk, it is essential to know the correct partition style to avoid errors during the Windows 10 installation. You may lose important data without preparing the correct USB disk drive. We recommend checking if the partition scheme on your device is GPT or MBR to be confident during Windows 10 installation that there are no chances of failure.

This post will guide you on how to check if the partition scheme is GPT or MBR.

Check if a Disk Drive is GPT or MBR in Windows 10

There are at least two ways to know if a disk drive is GPT or MBR in Windows; these are the following:-
  1. Check if a disk is GPT or MBR using Disk Management Tool
  2. Verify if a disk is MBR or GPT using Command Prompt

How to check if a disk is GPT or MBR using Disk Management Tool?

To check if a disk is GPT or MBR using Disk Management Tool, perform the following steps:-

Step 1. Right-click on the Start button and select the Disk Management option to open the Disk Management window.

Step 2. In the Disk Management window that opens, right-click on the disk and select the Properties option.

Step 3. In the Hard Drive properties dialog box, switch to the Volumes tab.

Step 4. Under the Volumes tab, next to the Partition style file, you can see partition style is MBR or GUID Partition Table (GPT).

Once you complete the above steps, you can resolve whether your disk drive supports GPT or MBR.

How to check if a disk is MBR or GPT using Command Prompt?

To decide if a disk is MBR or GPT using Command Prompt, do the following steps:-

Step 1. Open the Command Prompt as an administrator.

To run the command prompt as administrator, click on the Start button and type CMD, right-click on the Command Prompt entry, and select the Run as administrator option.

When User Account Control (UAC) prompts, click Yes to confirm.

Step 2. At the Command Prompt window that opens, type the following command and press Enter from the keyboard:-

Diskpart

Step 3. At the DISKPART prompt, type the following command and press Enter from the keyboard:-

List Disk

Once you complete the above steps, you can easily determine where your disk is GPT or MBR.

Note: If more than one hard drive is available on your computer or laptop, you use the above commands to check MBR or GPT. If a disk is GPT, an asterisk () mark will show up next to the disk. If the partition style is MBR, an asterisk () mark will not be visible next to the disk.
