Changing Boot Sequence for the Current Boot

You can use this feature, for example, to tell the computer to boot from the CD drive so that you can run the Dell Diagnostics on the Drivers and Utilities CD, but
you want the computer to boot from the hard drive when the diagnostic tests are complete. You can also use this feature to restart your computer to a USB
