Boot Sequence

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:
● Windows Boot Manager
● UEFI HTTPs Boot
● UEFI RST BC711 NVMe SK hynix 256 GB DOBN6093129YBH26
● ONBOARD NIC (IPV4)
● ONBOARD NIC (IPV6)
The boot sequence screen also displays the option to access the System Setup screen.
