Secure Boot Secure Boot is a method of guaranteeing the integrity of the boot path by

performing additional validation of the operating system and PCI add-in cards.

The computer stops booting to the operating system when a component is not

authenticated during the boot process. Secure Boot can be enabled in BIOS

setup or using management interfaces like Dell Command|Configure, but can only

be disabled from BIOS setup.

Enable Secure Boot Enables the computer to boot using only validated boot software.

By default, the Enable Secure Boot option is enabled.

For additional security, Dell Technologies recommends keeping the Secure Boot

option enabled to ensure that the UEFI firmware validates the operating system

during the boot process.

NOTE: For Secure Boot to be enabled, the computer must be in UEFI boot

mode and the Enable Legacy Option ROMs option must be turned off.

Secure Boot Mode Enables or disables the Secure Boot operation mode.

By default, the Deployed Mode is selected.

NOTE: Deployed Mode should be selected for normal operation of Secure

Boot.
