Problem with secureboot when enabling

Posted by Due-Artist379@reddit | buildapc | View on Reddit | 21 comments

So, trying to play Faceit which needs TPM 2.0 and Secureboot enabled.

I went into my BIOS to enabled both of them, got TPM 2.0 enabled easily and then the problem with Secureboot. I'm trying to enabled it, doing everything right, I got UEFI enabled and stuff, but when enabling Secureboot and then saving changes and restarting the PC with option ''Save changes & reset computer'' or such, then the PC turns on, monitor technically turns on but doesn't let me enter desktop, and when I enter BIOS (after the change save the Secureboot is on):

After clicking ''Don't save and exit'' it gives me an error: Invalid Signature Detected. Check secure boot policy in setup.
I have all the settings done right and everything seems okay. When disabling secureboot, everything works fine, but I need it enabled.

Already tried removing CMOS battery and doing a full restart, nothing... Could anyone help, please?
