Using MultiBoot

About the boot device order

As the computer starts, the system attempts to boot from enabled devices. The MultiBoot utility, which is

enabled at the factory, controls the order in which the system selects a boot device. Boot devices can

include optical drives, diskette drives, a network interface card (NIC), hard drives, and USB devices.

Boot devices contain bootable media or files that the computer needs to start and operate properly.

NOTE:

Some boot devices must be enabled in Computer Setup before they can be included in the

boot order.

You can change the order in which the computer searches for a boot device by changing the boot

order in Computer Setup. You can also press

esc

while the “Press the ESC key for Startup Menu”

message is displayed at the bottom of the screen, and then press

. Pressing

displays a menu that

shows the current boot devices and allows you to select a boot device. Or, you can use MultiBoot

Express to set the computer to prompt you for a boot location each time the computer turns on or

restarts.

Choosing MultiBoot preferences

You can use MultiBoot in the following ways:

●

To set a new boot order that the computer uses each time it is turned on, by changing the boot

order in Computer Setup.

●

To dynamically choose the boot device, by pressing

esc

while the “Press the ESC key for Startup

Menu” message is displayed at the bottom of the screen, and then pressing

Device Options menu.
