Cannot boot with Secure boot on or else I get that message. I have to have it off in order to boot.

Hey there, ​@Vul-Vokun-Ah 

I understand that you are unable to boot your Razer Blade with Secure Boot enabled, and that you receive the "Invalid signature detected. Check Secure Boot Policy in Setup" error message.

Could you please confirm if you have performed the troubleshooting steps in this link? If the issue persists after performing the troubleshooting steps, please send me a private message along with your device's serial number so I can check its details in our system and assist you further. Thank you!
