Changing Boot Sequence for the Current Boot
You can use this feature to change the current boot sequence, for example, to boot from
the optical drive to run Dell Diagnostics from the Drivers and Utilities disc. The previous
boot sequence is restored at the next boot.
1 If you are booting from a USB device, connect the USB device to a USB port.
2 Turn on (or restart) your computer.
3 When F2 Setup, F12 Boot Options appears in the lower-right corner of the
screen, press <F12>.
NOTE: If you wait too long and the operating system logo appears, continue to wait
until you see the operating system’s desktop. Then shut down your computer and
try again.
The Boot Device Menu appears, listing all available boot devices.
4 On the Boot Device Menu choose the device you want to boot from.
For example, if you are booting to a USB memory key, highlight USB Storage
Device and press <Enter>.
