Master Boot Record Security
The MBR contains information needed to successfully boot from a disk and to access the data stored on
the disk. Master Boot Record Security detects and reports unintentional or malicious changes to the
MBR, such as those caused by some workstation 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.
To enable MBR Security:
1 Turn on or restart the workstation. If you are in Windows, click Start>Shut Down>Restart.
2 Wait for the
F10=Setup prompt to appear on the lower right corner of the screen. Once you see the
prompt, press the F10 key to enter the F10 setup utility.
NOTE If you do not press the F10 key at the appropriate time, you must restart the workstation and try
again to access the utility.
3 Select Security>Master Boot Record Security>Enabled.
4 Select Security>Save Master Boot Record.
5 Before exiting, select File>Save Changes and Exit.
When MBR Security is enabled, the BIOS prevents any changes being made to the MBR of the current
bootable disk while in MS-DOS or Windows Safe Mode.
NOTE Most operating systems control access to the MBR of the current bootable disk; the BIOS cannot
prevent changes that might occur while the operating system is running.
