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.
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 is required to be in
UEFI boot mode and the Enable Legacy Option ROMs option is required to be
turned off.
When disabled, the UEFI CA is removed from the BIOS UEFI Secure Boot
database.
