MBR (Master Boot Record) is a traditional partition mechanism, which is applied to most PC devices using BIOS.

1.MBR supports 32bit and 64bit systems

2.MBR supports a limited number of partitions

3.MBR only supports hard disks not exceeding 2T, and hard disks exceeding 2T can only use 2T space (using other methods)

1. Primary partition: only 4 can be created at most 1 primary partition (available)

2. Extended partition: An extended partition will occupy a primary partition location (unusable, can be turned into a logical partition)

3. Logical partition: Linux supports up to 63 IDE partitions and 15 SCSI partitions (can be Use)

    Disk partition:

1. Enter root.

2. Enter fdisk -l
