Convert MBR to GPT in Windows 10 PC without Data Loss

Is it necessary to convert MBR to GPT in Windows 10 computer?

There is a significant amount of uncertainty among Windows 10 users on whether they should utilize the MBR or GPT structure. The largest amount of data that can be stored on a disk that can be accessible by MBR structures is 2TB. The excess capacity on a drive that is greater than 2 TB will be listed as “unallocated,” which means that it will not be available for usage or access under any circumstances.

Consequently, in order to maximize the usage of the large hard drive in Windows 10, it is necessary to switch the MBR to the GPT format. Alternately, if you want to upgrade your Windows 10 computer to Windows 11, you will need to choose the GPT option. The UEFI mode is the only mode that Microsoft Windows 11 first launches in.

Another thing you need to know is that the GPT disks will display “GPT Protective” partitions is something that you should be aware of if you are using an outdated system with GPT, such as Windows XP 32 bit or Windows 2003 32. This means that unless you convert the disk from GPT to MBR, you will not be able to access the data that is stored on it.

A conversion from the MBR to the GPT is required in order to make use of a more modern operating system, such as Windows 10 and Windows 11.

Use efficient tool to convert MBR to GPT in Windows 10 without data loss

Many times, people ask whether they should reinstall the OS if they wish to convert a system disk. Be careful if you wish to use Command Prompt to translate MBR to GPT since it only converts empty MBR drives to GPT. You will thus have to remove all of your current partitions, so running the danger of losing your data. Moreover, it is not a good idea to convert a system drive using the Command Prompt since the system partition cannot be erased while the disk is under use.

You can choose hard disk manager AOMEI Partition Assistant, a strong conversion program that allows you to convert both data disks and system disks between MBR and GPT in just three steps, therefore avoiding data loss and the need to reinstall Windows.

AOMEI Partition Assistant in MBR2GPT conversion offers the following benefits:

  1. On Windows 10, its simple-to-use graphical interface allows one to convert from MBR to GPT with just a few clicks.
  2. Keeping your data safe on several Windows versions, including 7, 8, 8.1, 10, and 11, it lets you change MBR into GPT.
  3. Apart from converting system MBR drives to GPT without removing any partitions, it can also do so by converting external MBR hard drives to GPT.
  4. Should you unintentionally convert a disk to GPT, this utility helps you to undo the GPT disk back to MBR.

Now, let’s see how to convert MBR to GPT on Windows 10 disk without data loss.

Note: Please make sure your computer supports the UEFI boot mode or change BIOS to UEFI to avoid boot issues if you need to change the system disk.

Step 1. Install and launch AOMEI Partition Assistant. When you enter the main interface, select the disk you want to convert to GPT whether it is a system disk or a data disk, right-click on it and select “Convert to a GPT” from the feature menu.

Step 2. It will pop up a window that you need to confirm. Click “OK” and you’ll be back to the main interface.

Step 3. Here you can see that the disk has been converted into GPT, but it’s not the end. You need to click “Apply” at the toolbar to execute the task.

You will be able to convert your MBR system disk to GPT in a seamless manner by utilizing this utility, which will allow you to keep all of your data and system configurations intact.

To sum up

The following is a guide to converting MBR to GPT in Windows 10. AOMEI Partition Assistant enables you to manage a variety of intricate disk management duties. These include the following: migrating the operating system drive to an SSD or HDD, moving applications or folders to a different drive, recovering files from an SSD, undertaking hard drive speed tests, and cloning an MBR disk to GPT.
