i have a NUC5i3RYH with an Adata SSD S511.
Installing OpenELEC and Ubuntu worked realy fine, but i have problems with Windows 7 64 Home.
During the Installation from a USB-Stick Windows says he is missing a driver for a CD/DVD player..
I dont have any such players. I tried all drivers from the official RYH-RYK-Win7-64bit-Driver-Bundle-Jan2015, but it did not helped.
The chipset driver is a .exe, so i don`t know where i could get a working driver for the chipset as a .inf.
After I used another win7 image, it works
It was the Windows image. I am glad you have your computer up and running.
