Table 6. BIOS Setup options—Boot Configuration menu(continued)

Boot Configuration Description

Enable Microsoft UEFI CA

When disabled, the UEFI CA is removed from the BIOS UEFI Secure Boot

database (‘db’ variable).

CAUTION: If you disable Microsoft UEFI CA, the computer may not

boot, computer graphics may not function, some devices may not

function properly, and the computer could become unrecoverable.

Microsoft HLK requirements for DeviceGuard require the UEFI 3

rd

Party CA

removal from the UEFI SecureBoot database (db).

Setting this option to Allow Pre-Boot Modules Only, will allow the UEFI 3

rd

party

CA to be used to validate pre-boot option ROMs, but will not allow a bootloader

signed with the UEFI 3

For additional security, Dell Technologies recommends setting the Microsoft UEFI

CA option to Enabled to ensure the broadest compatibility with devices and

operating systems.
