Someone mailed me some suggestions, but probably did it directly and the email does not show in the thread.
Anyway:
-The installer can take a long time to show up, so I left the pc on overnight, but nothing happens. When I woke up I got the same black screen.
- Keyboard layout is US International
- My Chipset is Intel i7-1165G7, which comes with Intel Iris Xe Graphics. I have no other GPU on my pc.
- For the boot messages yes, I can take pictures. The output is very arid tho. I managed to get more stuff printed on screen by following this suggestion:
...In which case output goes on forever until it says that boot failed.
I'll try to take some pictures of this later on today!
