BOOT RECORD Meaning and
Definition
-
A boot record, also known as a master boot record (MBR), is a crucial component located at the beginning of a computer's hard disk or storage device. It serves as the initial sector that is accessed by a computer's operating system and provides essential instructions for the system boot process.
The boot record contains information necessary for the computer to identify and initiate the booting sequence. It includes a small program known as the bootstrap code, which loads and executes the operating system's bootloader from a specific location on the disk. This code is responsible for identifying the active partition or volume on the storage device and transferring control to the operating system.
In addition to the bootstrap code, the boot record also contains partition table information that defines the different partitions or volumes on the hard disk. This table helps the system to locate and access the specific partition where the operating system is stored. Each entry in the partition table contains details like the starting and ending sector numbers, file system type, and whether the partition is bootable or not.
The boot record plays a crucial role in the computer's boot process and ensures that the operating system can be loaded into the computer's memory correctly. Any corruption or damage to the boot record can result in boot failures or an inability to boot the system. Therefore, it is essential to protect the boot record from malware or accidental modifications to maintain the proper functioning of the computer.

Etymology of BOOT RECORD
The etymology of the word "boot record" traces back to the early days of computer programming. The term "boot" is derived from "bootstrap", which refers to a looped strap or handle used to pull on a boot. In the 1950s and 1960s, computer systems were initially started by manually entering instructions to load the operating system. The process involves pulling oneself up by the bootstraps, as the computer would have to read the necessary code from a peripheral device (such as punched cards) to load the operating system into memory.
Over time, as computers evolved, the process became automated, and the initial instructions necessary to start a computer and load the operating system came to be known as the "bootstrap code" or "bootstrap loader". This eventually shortened to simply "boot code" or "bootloader".
