First, let’s check the status of Secure Boot. Click on the Windows “Start” button and type “msinfo32” into the search bar and press “Enter” to open “System Information”. In “System Information”, “System Summary” should be selected by default.
On the right side of the screen, look for “BIOS Mode” and “Secure Boot State”. If Secure Boot is enabled, the BIOS Mode will show “UEFI” and Secure Boot State will show as “On”. To enable Secure Boot in systems manufactured after 2021, turn on or restart your computer.
When the Dell logo appears, repeatedly tap the “F2” key to enter BIOS. Navigate to the “Boot Configuration” tab on the left menu. Set the boot mode to “UEFI” only and enable “Secure Boot”. Click on “Apply Changes” and exit BIOS.
To enable Secure Boot in systems manufactured before 2021, expand the “General” section. Select “Boot Sequence”. Set the “Boot List Option” to “UEFI”. Then, click on the “Secure Boot” section on the left menu and select “System Information”. Check the box next to “Secure Boot Enable”. Click on “Apply” to save the changes and then exit BIOS.
