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 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.
