MBRBootsektor
MBRBootsektor, or the MBR boot sector, refers to the first sector of a storage device used by BIOS-based computers to start the operating system. It is located in the Master Boot Record (MBR) at the very beginning of the disk and is 512 bytes in size. During boot, the system firmware loads this sector into memory and executes its boot code.
The MBR contains three parts: a 446-byte bootloader program, a 64-byte partition table describing up to four
Booting with the MBR follows a sequence typical of legacy BIOS systems. The BIOS reads the MBR
Limitations and variants: The MBR supports a maximum of four primary partitions, with additional partitions accommodated
In contemporary contexts, the MBR boot sector remains relevant for backward compatibility, recovery tools, and boot
