3.5.1 Master Boot Record Security
The Master Boot Record (MBR) contains information needed to successfully boot from a disk
and to access the data stored on the disk. Master Boot Record Security may prevent unintentional
or malicious changes to the MBR, such as those caused by some viruses or by the incorrect use of
certain disk utilities. It also allows you to recover the “last known good” MBR, should changes to
the MBR be detected when the system is restarted.
