Dell OptiPlex 3020–Mini Tower Owner's Manual

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
  • Diagnostics
    • NOTE: Choosing Diagnostics, will display the ePSA diagnostics screen.

The boot sequence screen also displays the option to access the System Setup screen.
