Thanks, the issue was with secureboot actually, I found how to disable it and I can boot again. As for nvidia I will wipe the disk from a live image and start over, I am not familiar enough with what you suggested to tackle it (for now…). Thanks a lot for the suggestion.
SSH in and forcibly uninstall all Nvidia packages, then reinstall them fresh following Nvidia’s website.
At least this has worked for me on Ubuntu on several occasions.
