So… Let’s boil it all down. First of all, it is not only Fedora 30. I tried to get a live USB of Manjaro (with GNOME) and I also had a black screen on boot. However, I actually can boot a live USB of Fedora 30 if I go to troubleshoot and start with minimal graphics. If not, it does the preparation and after the 4th-5th “[OK]” the screen goes blank. My monitor receives some kind of signal as it did not turn off (It automatically turns off and on when there is signal) and my computer was still running.
At first I thought waiting would do the trick but after 2h… You know what happens. I could not find a single solution to my issue as the secure boot is disabled and even with CSM disabled, I still get a black screen. Maybe it could be my USB? I will try with a new one later on, but I doubt that could be it.
