This article mainly introduces what are the differences between gpt and mbr, the article is very detailed, has a certain reference value, interested friends must read it!

Differences: 1, mbr supports up to 2T, while gpt is theoretically unlimited; 2, mbr supports up to four main partitions, gpt has no restrictions; 3, win7 can only use mbr partitions, from Win8 Microsoft recommends that you use gpt;4, gpt is started by uefi, compatibility and stability is not as good as bios+mbr.

MBR partition

MBR, which means "master boot record", was proposed by IBM company earlier. It is a special boot sector that exists at the beginning of the disk drive. This sector contains information about the installed operating system and uses a small piece of code to start the system. If you install Windows, its startup information is in this code-if the MBR information is corrupted or mistakenly deleted, you will not be able to start Windows properly, then you need to find a boot repair software tool to fix it. In Linux systems, MBR is usually the GRUB loader. MBR . When a computer starts, it starts the BIOS system that comes with the motherboard, and bios loads MBR,MBR and then starts Windows. This is the startup process of mbr.

GPT partition

GPT means GUID Partition Table, that is, the globally unique identification disk partition table. It is another more advanced and novel way of disk organization, a way of disk organization started using UEFI. At first, it was for better compatibility, but later it was widely used because of its larger memory support (mbr partitions support up to 2T disks) and more compatibility, especially for Apple's MAC system, which uses all gpt partitions. Gtp no longer has the concept of partition, and all CDEF disks are stored in a piece of information. It can be simply understood as a more advanced but not widely used technology.

The difference between the two

Memory support: mbr supports up to 2T, while gpt is theoretically unlimited.

Partitions: mbr supports up to four primary partitions, and there are no restrictions on gpt. If you want to run multiple systems, there are up to 4 mbr and there is no limit to gpt.

System: win7 can only be partitioned with mbr. Microsoft recommends that you use gpt from Win8.

Other: gpt is started by uefi, while uefi is a later concept, compatibility and stability are not as good as bios+mbr.
