MBR, EBR, DBR

(Reprinted! Mark it and watch it later at night)

 

These concepts are generally described as follows:

MBR: the code first loaded into memory and executed on the boot media after the computer is started. It is usually used to explain the partition structure. Take a hard disk as an example. Generally, it is 0 slice of LBA.

MBR is the abbreviation of Master Boot Record.

EBR: after Microsoft introduced the concept of extended partitions, the extended partitions follow the DPT structure used by the Basic partitions, generally, the partition table of an extended partition is called EBR, EMBR, extended MBR, or virtual MBR.

DBR: the first sector that can be accessed after the operating system enters the file system. It is usually used to explain the file system. In UNIX file systems, it is equivalent to superblock.
