MBR2GPT Tool: Convert MBR to GPT Windows 10 without Data Loss

When should you convert MBR to GPT in Windows 10?

MBR (Master Boot Record) and GPT (GUID Partition Table) are two partitioning schemes essential for Windows systems to locate files and programs. When initializing a disk, you must select either MBR or GPT. There are generally four instances in which changing an MBR drive to GPT on Windows 10 is beneficial:

Make full use of large disk space: The MBR can only handle disks of up to 2TB. To use more than 2TB of space, you need to convert MBR to GPT windows 10.

Create more partitions: MBR may support up to four primary partitions or three primary partitions plus one extended partition. GPT, on the other hand, allows for nearly infinite partitions.

Resolve installation errors: You may get the message “Windows cannot be installed to this disk” when installing Windows 10. There is an MBR partition table on the chosen disk. Windows can only be installed on GPT disks on EFI computers.” This problem is resolved when GPT is used.

Upgrade to Windows 11: Windows 11 requires UEFI boot mode, thus if you’re switching from Windows 10 to Windows 11, your system disk needs to be formatted as GPT. Consequently, the update requires changing the system disk’s MBR to GPT format.

Get Windows MBR2GPT converter to change MBR disk to GPT

If you aim to convert a system disk, a frequent worry is the need to reinstall the OS. Using Command Prompt for MBR2GPT conversion demands caution, as it only allows the conversion of empty MBR disks to GPT. This process requires deleting all existing partitions, posing a risk of data loss. Furthermore, converting a system disk through Command Prompt is impractical since the system partition cannot be deleted while it is in use.

To prevent data loss and avoid reinstalling Windows, consider using AOMEI Partition Assistant. It taps into the disk potential and manage partitions efficiently. This powerful conversion tool enables you to convert both data disks and system disks between MBR and GPT in just three simple steps, without impacting your data.

Here are the advantages of using AOMEI Partition Assistant for MBR to GPT conversion:

• Its modern, user-friendly graphical interface allows for easy MBR to GPT conversion on Windows 10 with just a few clicks.
• It supports data-preserving partition style changes to GPT across various Windows versions, including 7, 8, 8.1, 10, and 11.
• It can convert both system and external MBR disks to GPT without losing partitions.
• If you accidentally convert a disk to GPT, this tool allows you to revert the GPT disk back to MBR.
• In addition to converting MBR to GPT with no data loss, it also can help you copy partition to another drive, reset Windows password, move installed programs to another drive without any data loss and reinstalling.

Here are the steps to convert a disk partition style from MBR to GPT without reinstalling the OS or losing data using AOMEI Partition Assistant:

Note: If you need to replace the system disk, please make sure your computer supports UEFI boot mode or switch from Legacy to UEFI to prevent boot difficulties.

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.

Conclusion

From this passage, you now know the main distinctions between MBR and GPT as well as how to convert MBR to GPT without losing data or having to reinstall the operating system. If necessary, you can safely convert GPT drives back to MBR with the help of AOMEI Partition Assistant, a robust disk management application for not only Windows 10 but also Windows 11/8/7. Since 2010, it has been advancing global data security, serving a diverse community of more than 60 million users worldwide. Always feel free to use it.
