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 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

Device
and press <Enter>.
Changing Boot Mode for Future Boots

During POST, when the DELL logo is displayed, watch for the F2 prompt to appear and

The F2 prompt indicates that the keyboard has initialized. This prompt
can appear very quickly, so you must watch for it, and then press <F2>. If you
press <F2> before the F2 prompt, this keystroke is lost. If you wait too long and
the operating system logo appears, continue to wait until you see the operating
system’s desktop. Then, turn off your computer and try again.
