About MBR Disks
MBR is short for Master Boot Record, which is an old disk type but still used widely by many users. For a MBR disk, it only supports up to 4 primary partitions. In order to create more partitions, one primary partition needs to set as extended partition and then more logical drives are allowed to be created on it. Furthermore, the maximum size of a MBR disk is 2TB. What's the difference between MBR and GPT?
About GPT Disks
GPT stands for GUID Partition Table which takes full advantage of GUID (Globally Unique Identifiers) to define the partition. It is a part of UEFI standard. That’s to say, a UEFI-based system must use GPT disk. For a GPT disk, although 128 partitions are the limitation for a lot of systems, unlimited partitions can be created.

Tips and Tricks for MBR/GPT Disks Usage
Windows XP 32-bit, Windows 2000, Windows NT 4, or Windows 95/98 cannot read, write, and boot from GPT disks, they will see only the Protective MBR.
Windows XP x64 Edition can use GPT disks for data only.
All versions of Windows 10, Windows 8.1/8, Windows 7, Vista, Windows Server 2003, Windows Server 2008, Windows Server 2012, Windows Server 2016 and Windows Server 2019 can use GPT disk partition for data. Booting is only supported for 64-bit editions on UEFI-based systems.

Why Need to Make Conversion between MBR and GPT Disk?

Why Convert MBR to GPT?
The real disk size is more than 2TB, but system cannot use the whole disk space and only permit to use maximium 2TB. Besides, there are already 4 primary partitions on a MBR disk, but you plan to create more partitions. During Windows system installation, getting an error says: "Windows cannot be installed to this disk. The selected disk has an MBR partition table" or "On EFI systems, Windows can only be installed to GPT disks."
Why Convert GPT to MBR?
During Windows system installation, it comes an error: "Windows cannot be installed to this disk. The selected disk is of the GPT partition style. Operating system cannot support GPT disk." When you plug an external hard drive to your computer, it shows as " GPT Protective Partition".

The Features of MRB and GPT Disk Management Software
