Desktop Management Guide Before You Partition or Format the Current Bootable Disk Ensure that MBR Security is disabled before you change partitioning or formatting of the current bootable disk. Some disk utilities, such as FDISK and FORMAT, attempt to update the MBR. If MBR Security is enabled when you change partitioning or formatting of the disk, you may receive error messages from the disk utility or a warning from MBR Security the next time the computer is turned on or restarted. To disable 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. ✎ If you do not press the F10 key at the appropriate time, you must restart the computer and press and hold the F10 key again to access the utility. If you are using a PS/2 keyboard, you may see a Keyboard Error message-disregard it. 3. Select Security > Master Boot Record Security > Disabled. 4. Before exiting, click File > Save Changes and Exit. Cable Lock Provision The rear panel of the computer accommodates a cable lock so that the computer can be physically secured to a work area.
