3.5.4Master 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 computer viruses or by the incorrect use of certain disk utilities. It also allows you to recover the “last known good” MBR, should the computer detect changes to the MBR when the system is restarted.
To enable MBR Security, complete the following steps:
1.Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart.
2.As soon as the computer is turned on, press and hold the F10 key until you enter Computer Setup. Press Enter to bypass the title screen, if necessary.
