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
message is displayed at the bottom of the screen, and then press f9. Pressing
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.
