I just ran into problems while installing Fedora KDE and fixed them. I thought this might help some people.

  1. No problem: installing Live .iso on USB-Stick: Had fedora on another PC installed already, while struggling to open balenaEtcher I learned fedora media writer does the same but more simple. Easy install.

  2. Running the Live Version Installer: Freezes - fixed. Now the problem was starting. When I opened the installer two windows opened and closed really fast - then nothing. When I used it one more time after a few mins it just froze. -> Restart into Troubleshooting on USB -> Install worked perfectly.

Now I have my Computers on Fedora - one on KDE one on Gnome.
