Has anyone else hit a wall with Secure Boot during the Win11 upgrade? My PC meets all the other requirements, but the PC Health Check app says Secure Boot isn't enabled. I've gone into my UEFI (ASUS motherboard) and it *is* enabled. I even tried disabling and re-enabling it. Still getting the same error. What am I missing? Is there a specific mode it needs to be in?
First, double-check that your BIOS is set to UEFI mode, not Legacy/CSM—Secure Boot only works under UEFI. If that's already set, try clearing the Secure Boot keys and restoring defaults in your ASUS BIOS. Sometimes, a BIOS update can also resolve detection issues. If you're still stuck, try running the Microsoft Health Check tool again after a full reboot. Let me know if that works.
I had the same problem. On my ASUS board, I also had to switch the "OS Type" setting from "Other OS" to "Windows UEFI mode" before Secure Boot would actually work right.
Yeah, that BIOS update did the trick for me too. One extra thing: after updating, you might need to go back into the UEFI and manually re-enable Secure Boot again.
