I have an Asus Laptop which supports UEFI and Secure Boot, but Asus hide Secure boot option in laptops which didn't ship with Windows. I installed Windows 8.1 on it and now I want to enable Secure Boot and fast boot. Contacting Asus support had no result. I searched on the Internet and found this: rog.asus.com/forum/showthread.php?36766-Missing-Fast-Boot-CSM-amp-Secure-Boot-Options-in-Bios-why-only-for-Preinstall-Win-8&p=410987&viewfull=1#post410987 What do you know about it? Is it safe to do what that topic said?
