Hello everyone!
I have an iMac 10,1 (Late 2009, 21.5 Inch, Core 2 Duo E7600, ATI Radeon HD 4670) and I can't get Windows fully working on it. I've already tried a plethora of methods for install for which none of them works completely.
The main issue at hand is that after following the process of BCA, the system reboots to install Windows and my internal screen goes completely black while my external monitor works fine. Even after completing Windows installation, updating etc. I cannot for the life of me get the internal screen working.
Things I've tried to resolve the issue:
The only way I have managed to get the internal screen working is by installing in UEFI mode. However this uses the Basic Display Adapter. When I try to update using my GPU's drivers, the external monitor works but it corrupts my internal screen. Here's a picture [www dot ibb.co/HFn5G0R].
Any help would be appreciated

Things I've tried to resolve the issue:
- Reset SMC
- Reset PRAM
- Uninstall drivers in Safe Mode
- Re-installed different versions of the drivers (ones that BCA downloaded, ones directly downloaded from AMD support website for Win8/10, updated ones from Apple supposedly fixing the black screen issue).
- Booted from CD and using CMD deleted atikmdag.sys
- Erased/Re-installed Windows multiple times
