Hackintosh will only boot with CSM enabled.

EDIT: Should have said disabled in the title.....

I am Dual booting High Sierra and Windows 7 from two separate SSD's.

Windows 7 will only boot with CSM ENABLED and my MAC OS install will only boot with CSM DISABLED.

This means I have to go into the BIOS and toggle CSM whenever I want to switch my operating system.

This all started when I got a Radeon RX 560. With my old Geforce 8800gt I could boot MAC OS with CSM enabled no problem. I'm confused.....

Why does the 560 require CSM to be turned off?

Would some sort of SSDT edit solve this?

Any ideas would be appreciated.
