You post installed CLOVER UEFI boot loader to your OS X partition, achieved booting OS X UEFI but Windows 10 you can't. tonymacx86 has plenty of members in this community that have already posted guides to explain how to properly set up your Bios for UEFI boot so I won't be spending any time explaining this. It is most important that your bios settings are all properly set for UEFI booting. So again ->'Not For Legacy Booting' nor older motherboards that don't have ability for UEFI booting.
If you're using Clover legacy boot settings this guide won't be for you. This all inclusive guide is targeted for helping others using UEFI booting of Windows 10 alongside their OS X using the Clover boot loader 'UEFI' option installed on the OS X partition through latest EL Captain Multi-beast version 8xx.
This guide has no guarantee it will work for you as it did for me. This is a 'straight to the point' guide, not 'how I did it guide'. I find I enjoy helping other OS X self builder's and enthusiasts with their systems after I've been helped many times myself by this very community. Building a CustoMac Hackintosh: Buyer's Guide
