Master Boot Record

The very first sector of a physical disk (absolute sector 0) is called the master boot record. It contains machine code to enable the computer to find the partition table and the operating system. One of the first things a computer does when it starts up is to load this code into memory and execute it. This ‘boot code’ has a very simple task. Its job is to read the partition table at the end of sector 0 and decide how the disk is laid out, and which partition contains the bootable operating system.
