Black screen

[Franci01]

Straight install from Mojave, installation went through pretty fine but when it reboots I can’t see my ssd, only the install partition/volume. I try to boot in that but I reboots unless I use disablegfxfirmware in that case I have a black screen. RX580, i5 6500. Any idea??

Same issue here. Try moving your monitor connector to HDMI. Also using ATI Injector could help.
