Radeon 5770 works, GTX680 does not Win10

[Zeke D]

Since I couldn't get Windows7 to install in EFI mode, I went ahead and installed Windows 10.

My ATI Radeon 5770 works, and WIndows10 boots when I select it from the boot selector screen (Not if I use the boot disk selector in Settings.)

The MSI GTX680 TwinFrozr flashed with the eVGA mac bios only works immediately after installation, but then never again.

Any ideas?

Because there is the AMD driver for the 5770. AMD and Nvidia cards do not work at the same time. You need to remove the AMD driver.
