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. On completion
of the diagnostic tests, the previous boot sequence is restored.
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 Microsoft Windows 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>.
NOTE: To boot to a USB device, the device must be bootable. To ensure your
device is bootable, check the device documentation.
Changing Boot Sequence for Future Boots
1 Enter system setup. See "Entering System Setup" on page 95.
2 Use the arrow keys to highlight the Boot menu option and press <Enter> to access
the menu.
NOTE: Write down your current boot sequence in case you want to restore it.
3 Press the up- and down-arrow keys to move through the list of devices.
