What is the difference between gpt and mbr

Differences: 1. mbr supports up to 2T, while gpt is theoretically unlimited; 2. mbr supports up to four primary partitions, and gpt has no restrictions; 3. Win7 can only use mbr partitions, starting from Win8 Microsoft recommends that you use gpt; 4. gpt is started by uefi, and its compatibility and stability are not as good as bios mbr.

MBR Partition

MBR means "Master Boot Record", which was proposed by IBM in the early years. It is a special boot sector that exists at the beginning of the disk drive. This sector contains system information about the installed operating system and a small piece of code to boot the system. If you installed Windows, its startup information is placed in this piece of code - if the MBR information is damaged or accidentally deleted, Windows cannot be started normally. At this time, you need to find a boot repair software tool to repair it. In Linux systems, MBR is usually the GRUB loader. MBR. When a computer starts up, it will first start the BIOS system that comes with the motherboard. The bios loads MBR, and then MBR starts Windows. This is the startup process of mbr.

GPT Partition

GPT means GUID Partition Table, which is the "global unique identification disk partition table". It is another more advanced and novel disk organization method, a disk organization method that uses UEFI boot. Initially it was for better compatibility, but later it was widely used because of its larger supported memory (mbr partition supports up to 2T disks) and more compatibility, especially since all Apple MAC systems use gpt partitions. gtp no longer has the concept of partitions, and all CDEF disks are stored in a piece of information. It can be simply understood as a technology that is more advanced but not widely used enough.

The difference between the two

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

Partition: mbr supports up to four primary partitions, and gpt has no limit. If you want to run multiple systems, mbr can have up to 4 but gpt has no limit.

System: Win7 can only use mbr partition. Starting from Win8, Microsoft recommends that you use gpt.

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