I have 2010 cMP with a Sapphire RX580 Pulse and it will not boot in to Windows 10. If I select the “Boot Camp” disc as Start Up Disk in System Preferences, restart and get the screen “No Bootable Device”
It works with my old ATI HD 2600 or 5870 card, It also works with both cards installed (RX580 and 2600) on two separate displays using the alt key to use the boot manager and then unplug the 2600 cable.
Is there a way around this to use the RX580 only?
Running High Sierra
