The difference between mbr partition and gpt partition

The differences between mbr partition and gpt partition are as follows:

GPT can use hard disks larger than 2T, MBR does not support disks larger than 2TB, GPT can support unlimited partitions, regardless of the number of partitions and the size of hard disks, and the maximum support is 18EB. In addition, GPT is a new hard disk partition standard. MBR has at most four main partitions, and more than four main partitions can only be logically partitioned.

GPT is a new standard that gradually replaces MBR. It is supplemented by UEFI, so that UEFI replaces the old BIOS and GPT replaces the old MBR.

Comprehensive description of MBR partition

MBR, also known as the main boot sector, is the first sector to read when accessing the hard disk after the computer is turned on. MBR has the following functions:

1, first check whether the partition table in the hard disk is in good condition.

2. Find the bootable active partition from the partition table.

3. Load the data of the first logical sector in the active partition into memory. In DOS partition, the content of this sector is called DOS boot record, or DBR for short.

MBR is a very important department. Boot code is used to tell the computer how to handle the partition table and how to locate the operating system. The partition table is used to manage the partition of the hard disk, and the flag indicates that the sector is a valid boot record sector.
