Thank you for your answer. I just remembered I made some Timeshift backups before I tried to switch drivers. If I rollback to the backup will my keys be “overwritten” and I’ll be able to try to switch drivers again with no consequences?
Thanks for the answer! From the other answers I got in this thread it seems it’ll be safe to turn off Secure Boot, so I guess I’ll do that and try to boot again.
I did select to wipe the whole drive and install. And I wish I could install it with Secure Boot enabled but it seems thr only solution is to disable it.
