Why mbr damaged

The Master Boot Record MBR is created automatically when the disk has been initialized or the first partition on the hard disk is created. It is an important data structure on the disk. The Master Boot Record contains a small amount of executable code for the boot start and the Partition Table for the disk.

The location is always the first sector on the disk. The first 0x1BE bytes belong to the MBR itself, the next 64 bytes are the Partition Table, the last two bytes in the sector are a signature word for the sector and are always 0x55AA. What will happen if the first sector has been damaged physically or by a virus? In our demonstration example, to simulate a damaged MBR, we will overwrite precisely the first 16 bytes with zeros. Once upon entering this command you should hopefully see a message saying Completed Successfully.
