I have dd’ed over the ISO from the UM LTS and when I boot it on my Dell XPS 13 I always end up with “Booting kernel failed: Invalid argument”.
I have went under other options (F6) and went through all of those settings but none of them work. Also, I get 0 information before getting this error. I even tried switching TTY but there seems to only be this 1.
When I select test RAM (or anything else), I always end up with that same message. I know that the media/ISO is OK before it works on other machines.
Are you doing it from a bootable USB? The process might have gone sideways and not properly. You should try flashing your USB again and then boot it up…
As I totally NOT believed my ISO was corrupted, it was.
The root cause was: whenever you eject/unmounted a drive (after DD), you need to wait until the LED of your device stops flashing and GUI explicitly states you can safely eject (If if it takes more than 2 minutes to pop-up).
