Windows Upgrade Help and more

Ah, that Secure Boot error can be really stubborn even when it's enabled. Sometimes it's a firmware setting like having CSM or Legacy ROM enabled that can interfere—double-check that it's fully disabled in your BIOS. If you're still stuck, feel free to share your motherboard model and I can try to help you track down the specific setting.

I’m trying to upgrade my Windows 10 PC to Windows 11, but the PC Health Check tool says my system doesn’t support Secure Boot. I’ve checked my BIOS (UEFI) and it *is* enabled. I keep getting the error "This PC must support Secure Boot" with code 0x80070002. Has anyone else hit this wall? I’m not sure what else to check or if I need to change a specific setting. Any help would be appreciated!

+1 Did you also check if your disk is partitioned as GPT and not MBR?

Yeah, that's a solid point. Also, double-check that Secure Boot is set to "Windows UEFI Mode" and not "Other OS" in your BIOS.

Agreed. Sometimes a BIOS update from your motherboard manufacturer can also resolve that stubborn Secure Boot detection issue.

+1 You could also try clearing the TPM from within your BIOS settings, as that can sometimes reset the secure boot handshake.

Thanks! I turned off CSM like you said, but now my computer won't boot at all and just shows a black screen. What do I do?

Just tried this - works great!

This solution worked on my system too. Thanks!

Same here. Yeah, that error can be stubborn. One extra thing to check is if your disk partition style is GPT and not MBR, as that's also a requirement.
