To enable Secure Boot in MSI Click BIOS, follow these steps:

1. Enter the BIOS setup by restarting the computer and repeatedly pressing the Delete key during boot.
2. Navigate to the Advanced tab, then go to Windows OS Configuration.
3. Change the boot mode from CSM to UEFI. Save changes and reboot the system.
4. Re-enter the BIOS using the Delete key, go back to Advanced > Windows OS Configuration.
5. The Secure Boot option will now be available. Enable Secure Boot.
6. Save changes and exit BIOS. The system will reboot with Secure Boot enabled.

Additional notes:

• TPM (Trusted Platform Module) can also be enabled under the Security tab in Trusted Computing if needed.
• If Secure Boot options are grayed out, ensure the system is in UEFI mode, not legacy BIOS.
• After enabling Secure Boot, check Windows system information to confirm that Secure Boot is active.

These instructions apply generally to MSI motherboards with Click BIOS versions 1 to 5 and help ensure Secure Boot is properly enabled for security and Windows 11 compatibility.
