This feature allows you to change the sequence of devices that your computer
attempts to boot from. If the computer cannot boot from the device you select,
it attempts to boot from the next bootable device. You can use this feature to
change the:
• Current Boot Sequence — change the boot sequence for the current boot,
for example, to boot from the optical drive to run Alienware Diagnostics
from the Drivers and Utilities disc or to reinstall your operating system
using an external media. The previous boot sequence is restored at the next
boot.
• Future Boot Sequence — change the boot sequence for all future boots, for
example, to boot from the primary hard drive.
