MBR Protection—Protects the master boot record on
your computer's hard disk by prohibiting data from being
written onto the master boot record data area.
The master boot record is a special data area on the
computer's hard disk which is read whenever the
operating system is started.
It is recommended that you enable MBR Protection. If the
master boot record of the primary internal hard disk is lost or
damaged, the operating system is unable to start. This would
result in data loss and your hard drive would need to be
rebuilt.
