Master Boot Record. 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.
Master Boot Record. 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.
Master Boot Records. All hard drives contain master boot records. A master boot record (MBR) contains special information about files and operating system components on a computer. Master boot records are commonly infected by viruses because they are so easily infected and can be used to spread the virus quickly to other computer by infecting floppy disks used on an infected system.
( Master Boot Record, also called Partition Table)
The Master Boot Record (MBR) is the information in the first sector of any hard disk or diskette that identifies how and where an operating system is located so that it can be boot (loaded) into the computers main storage or random access memory.
This refers to the first sector on a hard disk or other disk media. When a computer boots up, it searches for a master boot record wherever the BIOS tells it to (usually the floppy first, then the primary C: hard drive) and based on what the master boot record says, loads up an operating system. Thus, if the master boot record becomes corrupt or is tampered with by a virus, it can cause your computer to be unable to boot.
Master Boot Record. 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.
A small program that is executed when a computer starts. It contains the sequence of commands required for the operating system to boot.
The first physical sector of the hard disk whose content is loaded to the main memory and executed by the BIOS. This code then either loads the operating system from a hard disk partition or a more sophisticated boot loader, such as LILO or GRUB.
The MBR is a small program stored on the first sector of a disk, which is executed when the computer starts up. The program determines from the partition table which partition to use for booting, and then transfers program control to the boot sector of that partition.
Master Boot Record. The first sector of a hard disk in a PC. It contains the Partition Table. 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.
Master Beneficiary Record
The Master Boot Record. A reserved space on a hard drive where information on what to do when booting is stored. LILO or other boot managers can be written here.
The Master Boot Record (MBR) is a file located in the first sector of the disk that contains a Master Partition Table describing the hard disk organization. The MBR also contains the Master Boot Code that loads the operating system from the disk's active partition.
Master boot record. The contents of the first disk block and the core data structure of a FAT32 partitionable disk.
Master Boot Record - The first sector of a hard disk drive. It stores information about partitions on that disk, the partition id, activity flag, starting cylinder/ head/ sector, and ending cylinder/ head/ sector. Four partitions are allowed.
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.
Abbreviation for master boot record.
Master Boot Record. When a hard drive is partitioned, the Master Boot Record is written to the first sector on the hard drive. It contains the Partition Table and other information needed by the BIOS to access the hard drive.
This is a first physical sector on the disk. Usually contains a small program-loader and Disk Partition Table. The program-loader checks the Disk Partition Table, determines in it an active logical disk, loads the disk Boot-sector into memory and passes control to it.
Master Boot Record. The first physical sector on a hard disk. It contains the master boot record program and information on how a hard disk is partitioned.
Master Boot Record: This is a peice of code that makes sense out the various drives you might have on a single physical hard disk and passes control to the bootsector on the appropriate logical drive.
Master Boot Record; very important part of your hard disk, contains partition table and IPL
Master Boot Record. The first sector of a hard drive, which by convention contains a loader program for starting an operating system.
master boot record. 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
