GPT to MBR: Can A GPT Disk Be Converted to MBR?

Read the full post: GPT vs. MBR

Set up a new disk on Windows 10 or 8.1 and you'll be asked whether you want to use MBR or GPT. As we know, MBR and GPT are two different ways of storing partitioning information, and each has its advantages and disadvantages. In general, GPT is seen as the future which is meant to improve upon the limitations of MBR including the storage limitations. However, many users still prefer MBR over GPT because it is still the most compatible and is still necessary in some cases.

Technically, there is no answer to "Is GPT or MBR better" because the right partition style is always the best. Following are some cases you must choose MBR over GPT. And if you currently use GPT, you'll need to change GPT to MBR by choosing one of the three solutions in the next part.

  • Choose MBR as a system disk if you have a 32-bit Windows to install.
  • Choose MBR for system disk if you're still using the very old Windows OS.
  • If you are running Windows XP or older systems, MBR is the only choice for system disk even if it is a 64-bit system.
  • Receive the error message "Windows cannot be installed to this disk. The selected disk is of the GPT partition style" during Windows installation.

It's allowed to change a partition style from GPT to MBR, or MBR to GPT. Windows inbuilt tools including Windows Disk Management and Windows Command Prompt are free conversion methods, only note that such conversion manners will cause a complete data loss.

To ensure that you convert GPT to MBR without affecting data inside, third-party software is an ideal choice. EaseUS Partition Master is known as the top-choice GPT to MBR converter, which enables all Windows 10/8/7/XP/Vista as well as Windows server users to convert a GPT disk to MBR disk with and without an operating system, at the same time, keep data intact.

Solution 1. Convert GPT to MBR with EaseUS GPT to MBR Converter (No Data Loss)

EaseUS Partition Master can directly convert GPT disk to MBR disk without any data loss (hard disk with the system installed is also supported). This partition magic software takes the risk and difficulty out of converting GPT to MBR, converting MBR to GPT, creating new partitions, or resizing partitions on hard disks.

As a comprehensive disk & partition conversion program, it supports conversion between GPT and MBR as you'll learn soon, it also supports the conversion of the following:

Compared with Disk Management and Command Prompt, it won't require a volume deletion thus no data loss would occur during the operation. Therefore, it is the safest and most reliable way that should come to the first place.

Follow the simple steps to convert GPT to MBR:


Step 1: Install and open EaseUS Partition Master on your Windows computer. 

open EaseUS Partition Master

Step 2: Right-click the GPT disk that you want to convert and select "Convert to MBR". Then, you will add a pending operation.

Step 3: Click the "Execute Operation" button at the top-left corner. Next, click "Apply" and begin to convert GPT disk to MBR. All data is safe with EaseUS partition manager software.

When you cannot boot into the operating system at the moment, you can still use the bootable EaseUS Partition Master to convert GPT to MBR without operating system. The operation is all the same as the above steps.

Solution 2. Convert GPT to MBR with Windows Disk Management

Before you convert a disk, back up important data to an external hard drive and close any programs that are accessing the disk. Also, you must have an administrator privilege to do this in Windows. Disk Management is installed by default and it's available on your Windows 10/8.1/8/7/XP/Vista computer.

Step 1. Open Disk Management as an admin by navigating to Control Panel > System and Security > Administrative Tools. Click Computer Management to open a new window.

Step 2. Under Storage, select Disk Management.

Step 3. To convert a disk from GPT to MBR here, you need to delete every volume. Right-click on a volume and select Delete Volume. Do this for all partitions.

Step 4. After deleting all partitions on the GPT disk, right-click on the disk and select Convert to MBR Disk.

After you convert GPT disk to MBR disk, you can create partitions on the now MBR disk if you like.

Solution 3. Convert GPT to MBR Using Command Prompt

Again, this Diskpart command method is based on deleting volumes and data. Back up your important data before proceeding.

convert gpt to mbr diskpart

Step 1. Open Command Prompt as an administrator and type diskpart.

Step 2. Type list disk and press Enter. Note the disk number that represents the GPT disk.

Step 3. Type select disk 1 if 1 is the GPT disk. Press Enter.

Step 4. Type clean and press Enter. This action will remove all the contents of the disk.

Step 5. Type convert MBR and press Enter. 

Step 6. Type exit to close Command Prompt after it's done.


After convert GPT to MBR disk you need to reboot the system, so don't worry if the computer is shutting down. To ensure the system bootable, you need to enter the BIOS. EaseUS Partition Master can help you convert disk between GPT and MBR easier and simpler. It can help you finish the job even you are a non-technician. Regardless, if you prefer using the command line, the Diskpart could be a good choice but you need to delete all the GPT volumes to start.
