    Secure boot has 4 requirements for Compatibility with windows 11. Many PC users are neglecting one aspect that Microsoft and the tech community do not talk about. You can implement all requirements and still realize that your PC is not booting or you cannot even access the bios to revert things back and give up on windows 11.
    The problem, as I had to deal with it is hardware incompatibility, particularly your graphic card that refuse to accept secure boot. The culprit was the Sapphire Radeon R9-290, not the R9-290X. I own both. the later works just fine.
