Before booting to the usb, the LLM did offer options to make me boot into a root prompt alternatively to the usb key, (but even there it was not booting properly, the failed services keeping displaying failures on the screen interfering visually with my inputting commands).

But as soon as I turned off the computer, and it no longer booted, I had to switch browser to an other machine to access the LLM and therefore could not access the context or conversation history which was stored in the browser and so the new LLM had no idea of all it had done before except from my prompt where I tried to explained what it had done.

Then from the live usb, the LLM made the situation even less recoverable when it started removing some system file in the hope to restore them cleanly with an apt install, probably because it didn't have a clue of the extent of the damages it needed to repair.

Thanks anyway, I'll try your solution if it happens again.
