the information in the first sector of any disk that identifies how and where an operating system is located so that the operating system can be loaded into the computer's memory
Each bootable partition has firmware that runs in the bios This firmware historically occupies the 446 bytes before the partition table A simple master boot record simply copies the operating system from the media into memory and turns computer control over to the operating system At power up, cold boot, or warm boot, the bios searches the computer storage media until it finds a master boot record which it then executes it The search locations and order differ between different bioses Often the search order is configuratble with firmware encoded in the computer hardware with the bios The most common search order is floppy, cdrom, network, usb disk, scsi disk, ide disk A more complex master boot record, called a boot manager, loads a program into memory that gives the user an opportunity to select which operating system to load
The data structure that starts the process of booting the computer The most important area on a hard disk The MBR contains the partition table for the disk and a small amount of executable code
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
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 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 computer's main storage or random access memory The Master Boot Record is also sometimes called the "partition sector" or the "master partition table" because it includes a table that locates each partition that the hard disk has been formatted into In addition to this table, the MBR also includes a program that reads the boot sector record of the partition containing the operating system to be booted into RAM In turn, that record contains a program that loads the rest of the operating system into RAM
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
The first sector of your hard disk that contains important stuff used when you boot your computer, including a partition table and a small program to read the table The program sees which partition to boot the operating system from and then transfers program control to the boot sector of that partition
