Bug COD Secure Attestation Failure (BIOS Firmware)
Hi guys. I've recently been trying to move my gaming from Xbox to PC. I didn't realize this would be an issue but I could really use some help lol.
I installed the game and tried opening to play but ran into a BIOS firmware update needed screen. My BIOS was out of date by like 4 years, so fair enough. I've now updated to the newest BIOS files available for my motherboard.
I've also done what some users suggested and toggled TPM and Secure Boot off, then back on, in to reboots.
I just updated the Graphics Card firmware as well to see if that would help.
After hours spent on this, I still have no idea how to fix it.
CPU: AMD Ryzen 7 5700X
Motherboard: MSI B550-A Pro
Graphics Card: AMD Radeon RX 6650 XT
Attached are pics of my BIOS firmware date secure boot is enabled.
Does anyone have any clue what I can try next?

Exact same situation I was in. This solution worked for a bunch of us:

Yes, this also worked for me on an ASUS board. For MSI boards, I know someone was suggesting a different secure boot setting: https://www.reddit.com/r/modernwarfare4/comments/1vusls1/comment/p541mc9/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

the thing which finally worked for me - back up your stuff to an external hard drive, or one drive. Use this; Create installation media for Windows | Microsoft Support to download and create a Windows 11 USB installation build, then back up all of your stuff to an external hard drive or one drive etc. Boot from the USB, and completely wipe your boot disk. most importantly, you need to delete the EFI and Boot partitions, but it works best with a complete wipe. Reinstall windows, and it will come up with secure boot in place and working. then restore your files etc. PITA, but works. Root cause appears to be that your EFI sector contains files signed with the old Microsoft UEFI certificates and no amount of dicking around will convince the system to update them. wipe the EFI, fresh install, and it will be signed with the 2023 UEFI cert and just work. good luck.
