What’s the difference between a MBR disk and a GPT disk? Figuring out those two questions, we’re able to know the reason why some users want to convert disk from MBR to GPT. Now, please allow us to introduce the main differences between MBR disk and GPT disk.
 
First of all, all Windows operating systems can support MBR disks, while GPT disks can only be supported by a few of them: Windows server 2003 SP1 +, Vista, Windows 7, Windows Server 2008, etc.
 
Secondly, the standard BIOS partition table is adopted by MBR disks while UEFI is used in GPT disks.
 
Most importantly, MBR disks support up to four primary partitions or three primary partitions and one extended partition, while up to 128 primary partitions are allowed in GPT disks. The maximum size of a single partition in MBR disks is 2TB, while that size can amount to 256TB in GPT disks.
