Boot Sequence
allows you to bypass the System Setup‐defined boot device order and
boot directly to a specific device (for example: optical drive or
hard drive). During the Power-on Self Test (POST), when the Dell logo
appears, you can:
Access System Setup by pressing <F2> key
Bring up the one-time boot menu by pressing <F12> key
The one-time boot menu displays the devices that you can boot
from including the diagnostic option. The boot-menu options are:
Removable Drive (if available)
STXXXX Drive
NOTE: XXX denotes the SATA drive number.
Optical Drive
Diagnostics
NOTE: Choosing Diagnostics, will display the ePSA diagnostics screen.
The boot sequence screen also displays the option to access
the System Setup screen.
