[Notebook] When starting up the laptop, a 'Secure Boot Violation' message appears

You might experience a “Secure Boot Violation” notice when the laptop boot, then it makes the system fail to boot into the Operating System.

 

To protect user's systems from malware attacks, ASUS Notebooks implement the Microsoft Secure Boot feature by default. This feature performs a legal loader check to boot into the OS. 

As Windows 7 does not support Secure Boot (http://technet.microsoft.com/en-us/library/hh824987.aspx), with the update of KB3133977, the system might detect inconsistent OS loader keys, resulting in boot failure.

In Windows 8/10 PC, the system might detect inconsistent OS loader keys and result in boot failure because you had the OS re-installed, installed with an OS other than the preinstalled version.

Please change the Secure Boot settings Bioses configuration as outlined in the steps below, this will allow the system to boot into the operating system successfully.

 

Please enter Bioses configuration first. Before the laptop power on, press and hold the [F2] button, then click the power button. (Do not release the F2 button until the Bioses screen display.) You can refer to the video How to enter the Bioses configuration.
