How to Check Disk Using GPT or MBR in Windows

How to Check If Disk Is Using GPT or MBR in Windows

Method 1: Use Disk Management

1. Press the key combination Win + X on your keyboard.
2. Select Disk Management from the menu that appears. Alternatively, you can press Win + R, type diskmgmt.msc, and press Enter.
3. In the Disk Management window, you will see a list of all disks connected to your computer, along with their partitions.
4. Identify the disk you want to check. These disks are usually labeled like Disk 0, Disk 1, and so on.
5. Right-click on the disk label you want to check (for example, Disk 0).
6. Select Properties from the context menu that appears.
7. In the Properties window, go to the Volumes tab.
8. Under Partition Style, you will see if the disk is using GUID Partition Table (GPT) or Master Boot Record (MBR).

Method 2: Use the Command Prompt

To check if your disk is using GPT or MBR in Windows, you can use Command Prompt. Here are the steps:

1. Press Win + X on your keyboard.
2. Select Command Prompt (Admin) or Windows PowerShell (Admin) from the menu that appears. Alternatively, you can press Win + S, type cmd, right-click on Command  Prompt, and select Run as administrator.
3. Type the following command in the Command Prompt window and press Enter:

diskpart

4. Once inside the DiskPart utility, type the following command and press Enter:

list disk

5. The DiskPart utility will display a list of disks connected to your computer. Note the GPT column in the list. If there is an asterisk (*) in the column, the disk is using GPT. If there is no asterisk, the disk uses MBR.

Method 3: Use PowerShell

You can also use PowerShell to check if your disk is using GPT or MBR. Here are the steps:

1. Press Win + X on your keyboard.
2. Select Windows PowerShell (Admin) from the menu that appears. Alternatively, you can press Win + S, type PowerShell, right-click on Windows  PowerShell, and select Run as administrator.
3. In the PowerShell window, type the following command and press Enter:

Get-Disk

4. PowerShell displays a list of all disks connected to your computer along with detailed information. Pay attention to the PartitionStyle column. This column will indicate whether the disk is using GPT or MBR.

How to Convert Disk from MBR to GPT or Vice Versa

Preparation Before Conversion

Before you perform the disk conversion from MBR to GPT or vice versa, make sure to:

• Backup Data: Make sure you have backed up all important data from the disk to be converted. Conversion can cause data loss, so make sure to back it up first.
• Pahami Risiko: Understand that the conversion process can delete all partitions and data existing on the disk. Make sure you are prepared for the risk of losing this data before proceeding.
