asrock how to enable secure boot

To enable Secure Boot on an ASRock motherboard, generally follow these steps:

1. Restart your PC and enter the BIOS setup by pressing the "Delete" key (or "F2" if Delete doesn't work) during the POST screen.
2. Navigate to the "Boot" menu, then find the "CSM" (Compatibility Support Module) setting and disable it if enabled.
3. Go to the "Security" tab and find "Secure Boot."
4. Set Secure Boot Mode from "Custom" to "Standard."
5. If Secure Boot options are locked, look for an option to install default Secure Boot keys (sometimes under Key Management) and restore factory keys.
6. After restoring keys, you should be able to enable Secure Boot.
7. Save your changes and exit the BIOS. Your PC will restart with Secure Boot enabled.

This procedure might slightly vary depending on your exact ASRock motherboard model, but these are the common steps to enable Secure Boot successfully.
