The Master Boot Record (MBR) is theinformation in the first sector of any hard disk or diskettethat identifies how and where an operating system is located sothat it can be boot (loaded) into the computer's mainstorage or random access memory.
.
Also, what is the use of MBR in Linux?
The MBR is the first sector of the computer harddrive that tells the computer how to load the operating system, howthe hard drive is partitioned, and how to load the operatingsystem. A master boot record (MBR) is the 512-byteboot sector that is the first sector of a partitioned data storagedevice of a hard disk.

What is master boot record and GUID partition table?
Master Boot Record (MBR) disks use thestandard BIOS partition table. GUID Partition Table(GPT) disks use Unified Extensible Firmware Interface(UEFI). One advantage of GPT disks is that you can have morethan four partitions on each disk. GPT is alsorequired for disks larger than two terabytes (TB).
