When the developers designed the size of thismaster partition table, they left just enough room for the description of four partitions, hence the four partition (four physical partitions) limit. Master Partition Table: This small bit of code that is referred to as a table contains a complete description of the partitions that are contained on the hard disk. The master boot record contains the following structures. When a computer starts and the BIOS boots the machine, itwill always look at this first sector for instructions and information on how to proceed with the boot process and load the operating system. This is the consistent starting point that the disk will always use. Do not confuse the master boot sector with, which are indeed different.The master boot record is always located at cylinder 0, head 0, and sector 1, the first sector on the disk.

The place where this information is stored is called the master boot record ( MBR), also referred to as the master boot sector or even just theboot sector. There also must be someplace where the BIOS can load theinitial boot program that starts the process of loading the operating system.

Master Boot Record Of This Hard Drive Is Damaged.

Toensure that the PC will always boot regardless of the BIOS code, both chip and BIOS manufacturers developed their code so that the processor, once turnedon, always starts executing at the same place, FFFF0h.Similarly, every hard disk must have a consistent 'starting point' where key information is stored about the disk, such as the number of partitions and what type they are. But, since the system memory is empty, the processor doesn't really have anything to execute, or even begin to know where to look for it. The Master Boot Record (MBR) and What it DoesThe Master Boot Record (MBR)andWhy it is Necessary? If you have arrived here through a search engine, and there's no menu to the left!When you turn on your PC, the processor attempts to begin the process of processing data.
