NOTE: Depending on the computer and its installed devices, the items listed in this section may or may not be displayed.
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
NOTE: Choosing Diagnostics, will display the ePSA diagnostics screen.
The boot sequence screen also displays the option to access the System Setup screen.
Navigation keys
NOTE: For most of the System Setup options, changes that you make are recorded but do not take effect until you restart the
system.
