Dell Precision Tower 5810 Owner's Manual

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:

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.
