Reserved sectors on disk that are used to load the operating system. On start-up, the computer looks for the master book record (MBR), which is typically the first sector in the first partition of the disk. The MBR contains pointers to the first sector of the partition that contains the operating system, and that sector contains the instructions that cause the computer to "boot" the operating system (from the phrase "pulling yourself up from your bootstraps").
The very first sector on a hard drive. It contains the codes necessary for the computer to start up. It also contains the partition table, which describes how the hard drive is organized. Also called the Master Boot Record.
sector on a disk containing information on how disk is organised - may contain a small boot program
The first logical sector of a drive. On a floppy disk, this is located on side 0, cylinder 0, sector 1. On a hard disk, it is the first sector of a logical drive, such as C: or D:. This sector contains the Boot Record, which is created by format. All drives that has been formatted contains a boot sector.
a part of the disk that is not part of any file
a portion of a bootable disk that is used to start the computer
a region of a HDD, floppy disk or other storage device (usually the first sector ) that is loaded into memory and executed as a part of the boot sequence
a sector on a disk that contains a bootstrap program
a special location on all disks, hard or floppy, where the Basic In/Out System (BIOS) of a computer looks during the booting of a computer for a bootable system
Area of a disk containing instructions enabling a computer to launch an operating system (such as Windows).
The portion of a disk reserved for the bootstrap loader (the self-starting portion) of an operating system. The boot sector typically contains a short machine language program that loads the operating system.
The first sector in the BIOS. It contains all the information required for the computer to start up.
Usually the first sector on any given partition. It contains a very short program (on the order of a few hundred bytes) which will load and start running the operating system proper.
First sector on a logical drive that includes code to boot that drive, specific logical drive information, and error messages.
This is the first sector of a bootable partition. It contains the information needed to start loading the operating system.
Instructions allowing the hard disk to load the DOS operating system. This record is one of the privileged targets for viruses, because it is executed at each computer power-on.
A sector that contains a loader program for starting an operating system.
A boot sector is a sector of a hard disk, floppy disk, or similar data storage device that contains code for bootstrapping programs (usually, but not necessarily, operating systems) stored in other parts of the disk.
