Boot Sequence; System Setup Options - Dell OptiPlex 5480 All-in-One Service 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:
• UEFI BOOT
○ Windows Boot Manager
○ Onboard NIC (IPV4)
○ Onboard NIC (IPV6)
• OTHER OPTIONS
○ BIOS Setup
○ Device Configuration
○ BIOS Flash Update
○ Diagnostics
○ SupportAssist OS Recovery
○ Change Boot Mode Settings
○ Exit Boot Menu and continue
