I have a 27" iMac 5K computer with AMD Radeon R9 M290X graphics. I have tried windows 8 as well as windows 10 and they both get error code 43 on startup for the AMD Radeon R9 M290X in device manager.
I have tried downloading and running the latest program from AMD website to install the graphics support and it reports that it can not find a AMD Radeon R9 M290X graphics.
I have also called both Apple Support and AMD Support with no answers. Has anyone successfully installed windows (8.1 or 10) with AMD Radeon R9 M290 drivers?
I know this is not a hardware issue as macOS Sierra has no issue with graphics card.
I see several post on the internet but no solutions that I can find other than use windows 7.
