Windows 11 MBR to GPT Convert Tool

One of the main requirements when upgrading your OS to Windows 11 is to convert your computer's MBR disk to GPT. This ensures that your computer remains secure even after the upgrade process. For Windows 11 users, GPT is preferred over MBR because it uses a more flexible boot mode.

MBR boots on Legacy mode, whereas GPT uses UEFI mode. Windows 11 developers consider GPT powerful since it works well on all modern hardware. Also, GPT doesn't limit the number of partitions and disk sizes. GPT users can create up to 128 partitions, while their MBR counterparts can only manage 4.

To successfully upgrade your computer to Windows 11, you'll need a good MBR to GPT convert tool. Read on as we discuss some of the best MBR to GPT conversion tools.   

What Is Windows 11 MBR to GPT Convert Tool?

Windows 11 MBR to GPT convert tool is a method that enables you to change the partition scheme of your computer from Master Boot Record (MBR) to GUID Partition Table (GPT) when upgrading to Windows 11.

The following are some of the most popular MBR to GPT conversion tools for windows 11 users.

EaseUS Partition Master has a competitive edge against other convert tools since it doesn't delete partitions during the conversion process. Therefore, no data loss occurs in the long run.

#2. CMD - Convert to GPT Command

Using CMD, you can pick an inbuilt diskpart tool to help convert MBR disks in your computer to GPT. One of the major requirements to apply this convert method is to perform a complete disk cleanup first. As a precautionary measure, you need to maintain a backup for all your disk data.

#3. Disk Management

An inbuilt disk management tool enables you to format, shrink, expand, or delete disks. It also helps during the conversion of MBR disks to GPT. Since this process entails deleting all partitions and creating new ones, you'll lose all the existing data. You should therefore maintain a data backup before getting started with this tool.  

#4. MBR2GPT.exe

MBR2GPT.exe enables you to add GPT features to the existing MBR partition on your device without modifying the existing partitions. Unlike the 2nd and 3rd methods, this method doesn't require you to make data backups. It's, therefore, a faster approach compared to the other tools.
