    Hello

    hi, I was using a R9-390x and I popped in a RX580, no problems with OSX, but bootcamp seems to be broken.
    I tested it by swapping back and forth and can very much confirm that bootcamp is not working.

    What could be the problem?
    I've tried loading the RX580 driver and stuff...

    The Windows was originally a windows 7 installation and upgraded to windows 10.

    I remember it was quite a PITA to install windows. Any way to get a windows ready image or something to just restore to a HDD?

    My Windows 10 works flawlessly with my RX580 on cMP.

    If you suspect it's driver issue.

    1) Boot to Windows with your 390X
    2) make sure it's connected to internet
    3) completely remove all GPU drivers
    4) shutdown
    5) swap in the RX580
    6) boot and WAIT

    Windows 10 should automatically download and install the correct driver for RX580. When I switch from 1080Ti to RX580, that "first boot" cost few extra minutes before the monitor can display the desktop.

    Anyway, it's not that hard to install Windows.

    Did you install it alongside or did you replace it? How many times did you try rebooting Windows consequently? What exactly is the issue: Black screen, frozen screen, etc?

    I did it one at a time.

    After installing the rx580 I did the different resets. I did the zap pr-ram and “on button long press” resets.

    I just get a black screen when I try to boot into windows. Occasionally I’ll get the “no boot disk” text line. (So the cable is not the problem?) or could it be booting into a different port? I’ve already tried the DVI and the display port, both shows the same response.

    I have no problem booting back into OSX.

    Once I swap back to the r9-390x I can boot into windows again.

    I’ve also tried to load the rx580 drivers, anything else I can try while I’m booting through the r9-390x?

    Thanks

    Have you tried booting more than 3 times consecutively? The thing is damn Windows 10 will not offer a Windows repair or an alternative boot option (safe boot) until 3 failed reboots. When I have similar issue I reboot to safe mode and reinstall the video driver. If it lets you repair or reboot with alternative options you can be certain it is a video driver issue.

    Thanks, let me try. So I just boot to the black screen and force a shutdown with the power button?

    That is correct. Just wait for a while making sure it does not try to do anything in the background

    Would like to report I managed to make it work.

    As it happened I was on windows 8, not 10. There are no drivers for windows 8, only 7 and 10.
    I managed to do the free upgrade to windows 10(link still works) and the screens boots up with no issue.
