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 is required to be in
UEFI boot mode and the Enable Legacy Option ROMs option is required to be
turned off.
Enable Microsoft UEFI CA When disabled, the UEFI CA is removed from the BIOS UEFI Secure Boot
database.
NOTE: When disabled, the Microsoft UEFI CA could render your computer
unable to boot, computer graphics may not function, some devices may not
function properly, and the computer could become unrecoverable.
By default, the Enable Microsoft UEFI CA option is enabled.
For additional security, Dell Technologies recommends keeping the Microsoft
UEFI CA option enabled to ensure the broadest compatibility with devices and
operating systems.
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.
