I'm building my first pc I hope to use the MSI B350 tomahawk motherboard. I want to install window 8.1 as I have already got a copy. I was looking through the manual of the motherboard and this is what it says

Windows OS Configuration Sets Windows detailed configuration and behaviors. Press Enter to enter the submenu. windows 10 WHQL Support [Disabled] Enables the supports for Windows 10 or disables for other operating systems. Before enabling this item, make sure all installed devices & utilities (hardware & software) should meet the Windows 10 requirements. [Enabled] The system will switch to UEFI mode to meet the Windows requirement. [Disabled] Disables this function. internal GOP Configuration Manages the onboard Graphics Output Protocol (GOP). Press Enter to enter the sub-menu. This sub-menu will appear when Windows 10 WHQL Support is enabled. secure Boot Sets the Windows secure boot to prevent the unauthorized accessing. Press Enter to enter the sub-menu. This sub-menu will appear when Windows 10 WHQL Support is enabled.

What is this and do I need to worry about it?
Also any other settings in the bios that I should worry about?
thanks
