I have been trying for 2 days now to get my dual boot working with High Sierra and today I actually got it working so I at least can get to the installer. I'm at the installer choosing the stuff I need for High Sierra and my Computer and I run into these problems.
When it is almost fully done with the installation I get the message that says "An error occurred while running scripts from the package "Network.pkg" and I restart the installer. When I'm at the start of the installer I unselect WiFi & Ethernet and try to run the installer. Then I get "An error occurred while running scripts from the package more "nVidia.pkg" and at this point, I have no idea what to do.
