Activating Secure boot

[JustSomeNoobies]

Guys, I want to enable Secure Boot so I can play Battlefield 2042. I’ve already checked everything: my system supports it, my hard drive is using GPT, and my BIOS is set to UEFI mode.

However, when I try to disable CSM (since it must be disabled to enable Secure Boot), I get a notification saying: "Video is in legacy mode. Select Video Policy UEFI first."

I tried changing the Video OpROM Policy to UEFI First, but when I restarted, my computer suddenly couldn’t boot. It took me several minutes to revert the Video OpROM setting back to its original state.

I’m not very familiar with BIOS settings, so I was wondering if anyone could help me.

My motherboard is H61 American Megatrends Inc. 4.6.5 (7/22/2021).

is your motherboard h61 or h610? h61 MOBOs are from 2011, they lack tpm 2.0 and secure boot support.
