I've been having some issues with my PC crashing, so I decided to do a factory reset. After the reset, my BIOS switched the secure boot setting back to "Other OS." I mainly play Valorant and wanted to change it back to "UEFI". However, every time I try to switch it, I get a red pop-up that says "Secure Boot Violation" when I leave the BIOS. I also updated the BIOS because it was an older version from 2022, but now the secure boot and key management options are grayed out, so I can't make any changes. Whenever I reset the BIOS settings, it changes back to "Other OS," but when I exit the BIOS, it reverts to "UEFI" again, and I can't access Windows. I've checked with local stores, but they want over $100 to fix it. Is there anything I can do myself to address this before spending that much?

Have you tried booting from installation media? If the TPM 2.0 chip on your motherboard is having issues, you might not be able to boot into Windows 11 unless you use a modified installation ISO that bypasses the TPM requirement.
If Secure Boot was activated and you changed something in the BIOS, it can block you from booting into Windows. That's intended behavior to protect against tampering. You might need to revert to your previous BIOS settings or consider a fresh Windows install. Can you tell me more about what you did for the factory reset?
What version of Windows are you using? Knowing if it's Windows 10 or 11 might help diagnose the issue better.

Yeah, I'm on Windows 11.
