MBR (Master Boot Record)

The Master Boot Record (MBR) is a special part of a computer's hard drive that helps the computer start up. It is located at the very beginning of the drive and contains essential information needed to identify and load the operating system. The MBR includes a small program called the bootloader, which initiates the startup process, and a table that describes how the drive is partitioned into different sections. Essentially, it acts as an entry point or roadmap, guiding the computer to find and load the operating system so it can be ready for use.
