How to Convert GPT to MBR Without Data Loss

When you convert GPT to MBR, losing data is an issue. AOMEI Partition Assistant Professional helps you.

You might come across a dilemma when your computer is already using GPT partitioning. Still, for some reasons, such as compatibility with an operating system, you need to convert GPT to MBR.

When it comes to the operating systems that can read from a GPT disk, more advanced Windows such as Windows 11, 10, 8.1, 7, and Server editions come to mind. Not to mention, only the 64-bit versions of the OS would support the GPT. Instead, MBR disks are supported by all Windows versions.

Thus, it comes a time that you require changing GPT to MBR; however, in those already partitions rest vital data that you can't afford to lose. You should find a solution for a clean conversion and, at the same time, keep your precious data.

With that being said, here, we offer several recognized techniques with thorough instructions.

What are GPT and MBR?

GPT and MBR are partition styles of a physical hard drive, the first is more advanced, and the second is for older systems.

  • GPT (short for GUID Partition Table) now is recognized as the latest standard layout for partition tables on hard disks of newer systems. It utilizes a UEFI firmware interface instead of BIOS, rendering the system faster and superior. Theoretically, with GPT, you can use a substantial hard disk (over 2 TB) and create an unlimited number of partitions, although 128 is the limit in practice. Dig deeper into What is GPT.
  • MBR (short for Master Boot Record) is less advanced and is gradually being replaced by GPT. It uses Legacy BIOS mode to be compatible with modern systems. MBR has its limitations and downsides compared to GPT. Unlike GPT, MBR only allows you to create a maximum of 4 primary partitions. (3 primary partitions and one extended partition). Dig deeper into What is MBR.

No wonder, every day, more users prefer GPT disk over MBR, yet there are still people who need to convert GPT disk to MBR Disk. Though GPT is far more qualified, at least for now, MBR is still compatible with a more significant number of systems and setups than GPT. And users might still need an MBR disk sometimes.

Reasons for Converting GPT Disk to MBR

GPT is the future, with more tempting features and improvements that trump MBR in many ways. With that in mind, MBR still attracts attention, considering it is the most compatible with older systems, and using MBR is necessary in some cases, such as:

For converting GPT to MBR, three recommended tools are more common and have the most results.

Convert GPT to MBR (Without Data Loss) - 3 Methods

Method 1: Convert GPT to MBR with Windows Disk Management

A convenient and accessible method since "Disk Management" is installed on most Windows by default. It's available on various operating systems, including Windows 11/10/8.1/8/7/XP and Vista.

First things first, make a backup of your crucial data to an external hard drive. Also, remember to close any programs that are accessing the disk.

To change GPT to MBR, proceed as below:

  • Step 1: Open Disk Management as "admin" through Control Panel > System and Security > Administrative Tools. Then, click "Computer Management" to open a new window.
open disk management
  • Step 2: Select "Disk Management" under the "Storage" bar.
  • Step 3:To convert a disk from GPT to MBR, you need to delete every volume. Right-click on a "Volume" and select "Delete Volume" for that to happen. After that, delete all partitions in the same way.
delete volume
  • Step 4: After deleting partitions completely on the GPT disk, right-click on the disk and select the "Convert to MBR Disk" option".

  • Step 5: now, you can create partitions on the currently MBR disk.

Method 2: Convert GPT to MBR Using Command Prompt

Another easy way of GPT disk to MBR conversion is using the "Diskpart" command, which is also based on deleting volumes and data. Therefore, you have to keep a backup of your important data before proceeding.

Again, this Diskpart command method is based on deleting volumes and data. Back up your essential data before moving forward:

  • 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. Then press "Enter" again.
  • Step 4: Now, this part is critical. Type "clean" and press "Enter" again. With that, you'll remove all the contents of that disk. So, make sure to have a backup beforehand.
remove all contents of the disk
  • Step 5: Type "convert MBR" and press "Enter." When it said, "successfully converted the selected disk to MBR format." You are done.
  • Step 6: Type "exit" to close "Command Prompt" after it's done.

Method 3: Convert GPT to MBR without Data Loss - AOMEI Partition Assistant

As mentioned in other techniques, the safest way to change GPT to MBR and avoid data loss is to have a backup beforehand, which is not always quickly done. A better solution is to use third-party software and proceed with conversion without data loss

In that case, AOMEI Partition Assistant Professional Edition is one of the most widely used GPT to MBR conversion tools. If you don't want to go through the lengthy data backup process and put them back again, the AOMEI Partition Assistant program can ease the procedure.

No matter what Windows operating system you use, AOMEI Partition Assistant can make the changing process convenient. It works very well with several operating systems, including Windows 7/8/10/11 and Windows XP.

Although GPT disks are more advanced than MBR disks, MBR still has compatibility, especially with older systems. Thus, it comes a time when you are forced to convert GPT to MBR.

The main objective is to prevent losing data when converting GPT to MBR. With most known methods, you need to have a backup beforehand, which is time-consuming and sometimes more complicated than it looks. Here we also offered a third solution using AOMEI Partition Assistant.
