Solution Steps
- 1 First, check if Secure Boot is enabled in your BIOS/UEFI. Restart your PC and press the key to enter BIOS (often F2, Del, or Esc). Look for 'Secure Boot' under 'Boot' or 'Security' settings. Ensure it's set to 'Enabled'. If it's disabled, enable it and save changes.
- 2 If Secure Boot is enabled but the error persists, reset the Secure Boot keys. In BIOS, look for 'Restore Factory Keys' or 'Reset Secure Boot Keys'. This resets the database of trusted certificates, which can fix policy violations.
- 3 Check your boot configuration. Open Command Prompt as administrator (Windows key + X → 'Terminal (Admin)') and type 'bcdedit /enum'. Look for any suspicious entries. If you see errors, you can rebuild the BCD using 'bootrec /rebuildbcd'.
- 4 If you recently installed a new operating system or changed boot devices, ensure the boot order is correct. In BIOS, set your primary hard drive as the first boot device.
- 5 If all else fails, disable Secure Boot temporarily to see if the error goes away. If it does, the issue is with a driver or bootloader that isn't signed. You may need to update your drivers or reinstall Windows.
