An important record located on the first sector of every hard disk drive. MBR contains a table of all of the hard disk drive's partitions, the location of the operating system, and a program that loads the operating system into the RAM. Loss of MBR leads to unrecoverable loss of data on the disk.
The simple low level code which is contained in the first sector of storage mediums, like hard drives, CDs, floppy disks, that contains code on how to use and load information from that medium. It also contains other information about cluster sizes and partition information. This information is located in the first track at the beginning of the drive or disk.
The contents of the first physical sector on a hard drive. This consists of the partition table, and the initial boot code which selects the active partition and boots it.
On all PC fixed disks, the first physical sector is reserved for a short bootstrap program. This sector is the Master Boot Record (MBR). It also includes the partition table. See also Boot Sector.
This is the area of a hard disk drive that contains critical information for the booting of the system. A popular target of virus developers. You can replace a damaged MBR with a generic MBR by using the FDISK program with an MBR switch. This should work in a system with a single DOS partition.
The 340-byte program located in the Master Boot Sector. This program begins the boot process. It reads the partition table, determines what partition will be booted from (normally C:), and transfers control to the program stored in the first sector of that partition, which is the Boot Sector. The Master Boot Record is often called the MBR, and often called the "master boot sector" or "Partition Sector".
The first sector on a hard drive, which contains the partition table and a program the BIOS uses to boot an OS from the drive.
The first logical sector on a disk containing the partition table and master boot loader.
Name given to the first sector of a bootable hard drive. The MBR contains the code used to load the operating system into memory or a bootloader (such as LILO), and the partition table of that hard drive. MIME
Master boot record is the first physical sector of a boot device (floppy, hard disk, or CD-ROM, etc.) During the process of booting up the system uses the master boot record of the first device. It usually contains a small program...
The master boot record (or MBR) is a section of a disk drive's storage space that is set aside for the purpose of saving information necessary to begin the bootstrap process on a personal computer.
(MBR) The first logical sector on a disk, this is (usually) where the BIOS looks to load a small program that will boot the computer.
The first sector of a hard disk in a PC. It contains the Partition Table.
The 340-byte program located in the master boot sector. This program reads the partition table, determines what partition to boot and transfers control to the program stored in the first sector of that partition. There is only one master boot record on each physical hard disk. Also: MBR, Partition Table; See Also: Boot Record
(MBR)/ boot sector infector (BSI) A virus that infects the system's master boot record on hard drives and the boot sector on floppy diskettes. This type of virus takes control of the system at a low level by activating between the system hardware and the operating system. An MBR/boot sector virus loads into memory during boot-up, before virus-detection code executes.
The first physical sector on a hard disk. It contains the master boot record program and information on how a hard disk is partitioned.
First sector on hard drive. Contains program for booting and the partition table.
The first sector of a hard drive, which by convention contains a loader program for starting an operating system.
The first sector on a hard disk, which starts the process of booting the computer. The MBR contains the partition table for the disk and a small amount of executable code called the master boot code. See also: Recovery Console; partition boot sector
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 Boot Sector.
The first sector on a hard disk or other disk media. When a...
A master boot record (MBR) is the first sector ("sector zero") of a data storage device such as a hard disk. It is sometimes used for bootstrapping operating systems, sometimes used for holding a disc's partition table, and sometimes used for uniquely identifying individual disc media; although on some machines it is entirely unused and ignored.
