Hello,
I have the same issue as the one reported here:
Secure Boot Violation – Invalid signature detected
Pattern:
Happens after shutdown (not just once, keeps repeating)
If I disable Secure Boot → system boots fine
After next shutdown → error comes back again
What I’ve tried:
Reset Secure Boot keys
Enable/disable Secure Boot
Checked BIOS → already up to date
So far nothing fixes it permanently.
What is the permanent fix or does Razer recommend that I keep secure boot disabled?
