Disable ASUS Motherboard's UEFI secure boot

Most new ASUS motherboards do not have the option to let users to turn off the UEFI secure boot. The “Secure Boot Enabled” is always greyed out and unable to change that option. Yet, we do have the option to disable the secure boot by clearing secure boot keys.

This is reversible so no need to worry about breaking the warranty or damaging the BIOS. BIOS’s Secure Boot menu should show Secure Boot state as “enabled” and Platform Key (PK) state as “loaded”

Uefi Secure Boot

To disable the UEFI secure boot:

1. Make sure the “OS Type” is “Windows UEFI”

2. Enter “Key Management”

3. Select “Clear Secure Boot keys” (You will have the option “Install default Secure Boot keys” to restore the default keys after you cleared the Secure Boot Keys)

Clear Secure Boot Keys

After you cleared the Secure Boot Keys, Secure Boot will be automatically disabled. You can set the OS Type to Other OS now.
