What is a boot sector? All disks and hard drives are divided into small sectors. The first sector is called the boot sector and contains the Master Boot Record (MBR). The MBR contains the information concerning the location of partitions on the drive and reading of the bootable operating system partition. During the bootup sequence on a DOS-based PC, the BIOS searches for certain system files, IO.SYS and MS-DOS.SYS. When those files have been located, the BIOS then searches for the first sector on that disk or drive and loads the needed Master Boot Record information into memory. The BIOS passes control to a program in the MBR which in turn loads IO.SYS. This latter file is responsible for loading the remainder of the operating system.
