Boot Sequence
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 (if available)
•
SATA Hard Drive (if available)
•
Diagnostics

Choosing Diagnostics, will display the ePSA diagnostics screen.
The boot sequence screen also displays the option to access the System Setup screen.

During POST, when the DELL logo is displayed, watch for the F2 prompt to appear, and then press F2 immediately.
NOTE:
The F2 prompt indicates that the keyboard is 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 desktop. Then, turn off your computer and try again.
