Windows 8.1 on VHD problem

Hi all,

Actually I have windows 10 on my Acer laptop, I have created a virtual Hard disk and installed Windows 8.1 to it.
After booting Win 8.1, I cant see my Graphics Card and Wireless Network Adapter.
They're not on Device Manager.

What should I do to access WIFI and Graphics Card?
My Graphics Card is Nvidia GE Force 940MX.
Thank you in advance.

Boot into the Windows 8.1 VHD and them run the Driver Setup to install the needed driver(s)
