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

devices and allows you to select a boot device. Or, you can use MultiBoot Express to set the computer to
