How to Convert MBR to GPT in Windows 11 Easily (3 Ways)

Reasons for Converting MBR to GPT in Windows 11

Since Windows 11 offers significant improvements in the user experience and also adds a bunch of new, powerful features, you may want to install Windows 11 and explore this new operating system for yourself. And this year Windows 11 will also release its first major feature update, called "Sun Valley 2", or version 22H2. This update restores support for drag-and-drop, improves Start menu customization, and much more.

For users who want to upgrade to Windows 11, there is a question that they are very concerned “Does Windows 11 use MBR or GPT?” According to the Windows 11 minimum requirements released by Microsoft, Windows 11 will abandon the old MBR partition scheme and switch to the GPT scheme. This is also in order to make your Windows computer more secure. So, if you want to upgrade to Windows 11, you need to convert your current MBR disk to a GPT disk.

Then, what are the MBR and GPT for disk? MBR and GPT are two different partition styles that are commonly used in storage devices, such as computer hard drives. They correspond to different boot modes, MBR to Legacy mode and GPT to UEFI mode. GPT is more flexible and compatible with modern hardware than the MBR partition style. The biggest advantage of GPT is that it has no limits on the size of disks and the number of partitions. On MBR disks, users can create up to 4 partitions. While users can create up to 128 partitions on GPT disks.

How to Convert MBR to GPT for Windows 11 Easily

If your disk is still MBR, it needs to be converted to GPT before you update to Windows 11. Many users will ask: How do I change from MBR to GPT in Windows? Don't worry, next, this article will introduce you  3 simple methods, including built-in tools and professional third-party software.

👉 Method 1. Convert MBR to GPT in Windows 11 using Disk Management
👉 Method 2. Convert MBR to GPT in Windows 11 using Diskpart
👉 Method 3. Convert MBR to GPT in Windows 11 using Third-party Software🔥

Method 1. Convert MBR to GPT in Windows 11 using Disk Management

The built-in tool - Disk Management helps you expand, shrink, delete and format volumes and disks. It also allows you to convert MBR disks to GPT disks.

However, during the conversion process, it will delete all your partitions and then create a new one using the unallocated space, so you will lose all your previous data. Please make a backup of your partitions in advance. Then you can follow the steps below.

Step 1. Right-click the Windows icon and select Disk Management.

Step 2. Right-click the volumes of the target disk, select Delete Volume and repeat this operation to delete all volumes.

Step 3. When the disk is displayed as unallocated space, right-click the disk and select Convert to GPT Disk. And finish all the rest steps.

Close Disk Management when the conversion process is done. You can now use your GPT disk to create partitions as you want or install a new OS on the disk.

Method 2. Convert MBR to GPT in Windows 11 using Diskpart

Besides the first method, you can also choose another built-in tool Diskpart to help you convert MBR disks to GPT. Since converting MBR to GPT with Diskpart requires cleaning up the whole disk, remember to backup your disk data first. Then follow the steps below.

Step 1. Click the Start button and type cmd. Then right-click Command Prompt and select Run as administrator.

Step 2. Type diskpart and click Enter.

Step 3. Type the following commands one by one and hit Enter each time.

• list disk
• select disk 1 (you need to choose your MBR disk.)
• clean
• convert gpt

Step 5. Type exit when the conversion process completes.

Method 3. Convert MBR to GPT in Windows 11 using Third-party Software

When using the first two MBR to GPT conversion tools you need to be aware that both Disk Management and DiskPart can only convert an empty MBR disk to GPT. Therefore, It requires you to delete every existing partition on the MBR disk, which will cause data loss.

If you want to convert MBR to GPT without deleting the volume and losing data, the third-party partition software - AOMEI Partition Assistant Professional can best meet your requirements. It's an MBR to GPT converter as well as a GPT to MBR converter. As a result, whether you're converting MBR to GPT or GPT to MBR on Windows 11/10/8/7, it can ensure a successful conversion with keeping all partitions secure on the target disk.

Now, you can download AOMEI Partition Assistant Professional and install it. Then follow the steps below.

Step 1. Open the software and right-click on the MBR disk that you want to convert then choose the Convert to GPT Disk option.

Step 2. Click OK on the pop-up window to confirm the operation.

Step 3. Click Apply button to commit the conversion.

Note:

This software also supports converting GPT to MBR. If you want to convert GPT to MBR without operating system, you can create a bootable media, boot your PC from it to enter Windows PE mode to finish the conversion

How to Change the Boot Mode to UEFI

When you have converted MBR to GPT in Windows 11, then you should go to BIOS to change the boot mode to UEFI. The following graphic tutorial will show you how to do that.

Step 1. Shut down and restart your computer. Keep pressing the F2/F9/Del (different computer may have different key ) to enter the BIOS setting.

Step 2. On the Boot menu, Select UEFI/BIOS Boot Mode first and use the up and down arrows to select UEFI, and press Enter.

Step 3. Press F10 to save the changes and exit.
