is there a reason why the recovery mode (single mode) is disabled by default and only a fallback kernel is there? It would be so much easier to solve common problems here without the need of a boot disk. Like this one on ubuntu: https://launchpad.net/ubuntu/+source/friendly-recovery
- Set fsck to force check / or check other partitions.
- Clean reinstall nvidia drivers.
- Check packages… clean cache…
- repair grub
- get systeminformation (inxi) and upload it if needed.
- Try to free up space.
I mean you cannot expect that everyone has a flash drive ready everywhere.
