Why Convert MBR to GPT 

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.

  • 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.

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.
