Why Convert MBR to GPT (3 Reasons)

Users want to convert MBR to GPT for various reasons. Usually, people convert MBR to GPT due to three reasons: disk replacement, system upgrading, and personal willingness.

A GPT disk supports larger than 2TB volumes while MBR cannot. If your bigger MBR disk is larger than 2TB, you'll need to convert it to GPT. Then you can break the 2TB limitation to make full use of the disk.

  • You want to upgrade or install the OS

When installing or upgrading the operating system, you might be asked whether you want to use MBR or GPT partition table format.

If the motherboard on your computer supports UEFI, choose GPT. (If you have UEFI boot problem, fix it by following this guide - Fix UEFI Boot in Windows 10/8/7.)

If the motherboard uses the legacy BIOS system, choose MBR. 

  • Personal willingness

GPT does not have limitations that MBR suffers from. GPT can hold a nearly unlimited number of partition and there is no need to create an extended partition to make them work. As a result, most people would like to convert MBR to GPT. But the problem is how to convert MBR to GPT without data loss? Here, you can learn the way to convert to GPT easily and quickly.

How to Check the Partition Style of a Disk

You must identify the disk type before you are going to convert to the target type. The easiest way to identify the disk type is by using Disk Management. Under Windows Disk Management, you can check the partitioning scheme of a hard drive:

Step 1. Right-click "This PC" and choose "Manage".

Step 2. Go to "Disk Management".

Step 3. Right-click the disk you want to check and choose "Properties".

Step 4. Go to the "Volumes" tab and you will see the partition style under the disk information.

The Best MBR to GPT Converter - EaseUS Partition Master Free 

Windows Disk Management can change MBR to GPT disk for free, but it only supports to convert a non-partitioned hard disk.

You can use free third-party partition management software to convert a hard disk from MBR to GPT. EaseUS Partition Master is our recommendation.

There are some hot topics about MBR and GPT on the internet. You can find the answers here:

1. Can MBR be converted to GPT?

Yes. If you are using Disk Management, you can change a disk from MBR to GPT partition style as long as the disk contains no partitions or volumes. If you want to convert the system disk to GPT, you need to get EaseUS partition software. 

2. How do I change from MBR to GPT in Windows 10?

In general, there are 3 ways to convert MBR to GPT.

  1. 1. Convert MBR to GPT using EaseUS MBR to GPT converter.
  2. 2. Convert MBR to GPT Windows 10 with Disk Management.
  3. 3. Convert MBR to GPT via Diskpart.

3. What is GPT format?

GPT, GUID Partition Table, the format used to define the hard disk partitions in computers with UEFI startup firmware. The GUID Partition Table (GPT) replaces the previous master boot record (MBR) method. While the MBR supported partitions as large as 2.2TB, GPT partitions can be up to 18 exabytes.

4. What is UEFI boot mode?

UEFI stands for Unified Extensible Firmware Interface. It's a modern solution to be gradually replacing the legacy BIOS on PCs since the introduction to Windows with Windows Vista Service Pack 1 and Windows 7 in 2007. It can do a lot more than a BIOS. It may be stored in flash memory on the motherboard, or it may be loaded from a hard drive or network share at boot. Different PCs with UEFI will have different interfaces and features.

5. Should I use MBR or GPT?

It depends on your disk space. If your hard disk is larger than 2TB, GPT is better than MBR. If your computer is BIOS-based, choose MBR for the system disk instead; If you use a disk under 2TB for data storage, both GPT and MBR are OK.
