Boot Sequence
Boot sequence enables 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:
XXXX denotes the SATA drive number.
● Optical Drive (if available)
● SATA Hard Drive (if available)
● Diagnostics
NOTE:
Choosing Diagnostics, displays the SupportAssist screen.
The boot sequence screen also displays the option to access the System Setup screen.
