If you have the option, make sure Secure Boot is set to Standard instead of Custom. I've heard of some that've had it set to Custom instead of Standard. Try disabling CSM within your BIOS if your hardware is old, should be located within Boot or Advanced section. Also check if your Trusted Platform Module (TPM) is enabled. If it's not, Secure Boot will fail. Could also try making sure it's updated although it likely already is. Failing that, you could try flashing the latest BIOS version from your motherboard manufacturer.
