Hello, I have a dual boot setup on my PC with separate installs of Windows and Fedora 43 on different drives. I’ve been loving Fedora so much that I’ve barely been booting into Windows, but I did the other day and of course got hit with a Windows update. I was already on 25H2 so this was a minor patch on the Windows side (though I’d have to look up the exact update).
Either way, when I rebooted following that update, I saw some red LED’s on my motherboard and then a message stating:
Secure Boot Violation: Invalid signature detected. Check Secure Boot Policy in Setup.
I disabled Secure Boot and was able to get back in to both OS’s, however this is far from ideal.
I would really appreciate some guidance on how to address this. Thanks!
