Has anyone been able to get Secure Boot to work with DZ77GA-70K?
Finally managed to get UEFI to work after updating the BIOS on my GTX660 TI. Everything working except Secure Boot. Did I need to do Secure Boot when I installed Windows 8? It was my understanding I could enable after install.
I am also running the latest 0061 BIOS for the DZ77GA-70K. I can go to secure boot and enable it in BIOS screen, but when i log into windows and check using: msinfo32 i see that Secure Boot is off 
Were you able to get it to work dislikeyou?
