Dear Razer Support,

Model: Razer Blade 15 Advanced (RZ09-0367CEC3)

Recently, my laptop started displaying the following error message during boot:

“Secure Boot Violation – Invalid signature detected. Check Secure Boot Policy in Setup.”

When this happens, the system refuses to boot into Windows. I have to disable Secure Boot in the BIOS. However, once I off my laptop and on it the next day, the situation will occur again.  It has been for months since it had happened.  I have ran out of ideas how to resolve it. Please help.  Thanks.

    Hey there, ​@finntay 

    I understand that your Razer Blade 15 Advanced is repeatedly showing a “Secure Boot Violation – Invalid signature detected” error during startup, preventing the system from booting into Windows unless Secure Boot is disabled.
