Now let me explain the problem and only valid solution(s) .
Back on Windows 7 they did a unified installer to install both the Intel and Ati cards all together .
This particular driver had the technology to let both cards work simultaneously as the "Dynamic Switchable Graphics Technology" for Amd which would allow the use of 2 graphics cards simultaneously wasn't out yet for such setup .
So they had to do custom work to make both GPUs work .
The reason why if you install latest Amd and Intel drivers only one of the two drivers will work is that both drivers react as if it was a desktop setup where you have to disable the Intel driver in bios like desktop PC owners do .
So the solutions you have are the following :
1 - Install both final supported drivers possible for Intel and Ati then on restarting enter bios , then disable the Intel GPU if found as an option inside bios (Check bios for such option before you do that move) and live with the Ati GPU which is slightly better than the Intel's and call it today .
2 - See to disable the Intel GPU in device manager as a mean to activate the Ati GPU . (Schedule a restart to safe mode before taking such a move in case you get a black screen you can enable it back in safe mode)
3 - Port the working driver that could do switchable graphics to Windows 10 , install it then update both drivers after .
4 - If that fail then learn to live with the ported driver from Windows 7 which misses OpenCL but the rest can do .
Try these and let me know
