How Does the Mbr Work?
A master boot record (often shortened asMBR) is a kind of boot sector stored on a hard disk drive orother storage device that contains the necessary computer code tostart the boot process. The MBR is created when a hard driveis partitioned, but it's not located within apartition.

.

Just so, what is the basic purpose of the MBR?

The Master Boot Record (MBR) is theinformation in the first sector of any hard disk or diskette thatidentifies how and where an operating system is located so that itcan be boot (loaded) into the computer's main storage orrandom access memory.

Furthermore, is MBR a bootloader? A boot loader is a program which loads a program( usually OS) to start a computer e.g. GRUB, windows loader. On theother hand an MBR is a sector in a MBR (GPT is newerstyle) hard-disk.

Furthermore, how does MBR get corrupted?

Causes. MBR errors can have three differentcauses: a virus infection, a drive failure or an MBRoverwrite caused by a program. Virus infections happen when a virusis loaded onto your computer. Many viruses target the masterboot record, since this is the most important part of your harddrive.

Does Master Boot Record delete data?

You can delete the mbr (master bootrecored) using the dd command itself. A master boot record(MBR) is the 512-byte boot sector that is the firstsector of a partitioned data storage device of a harddisk.
