Re: Might be time...
After having Ubuntu installed on the internal SSD on my daughters chrome book, I borrowed it one day and accidentally pressed space after switching it on thereafter leading to hours of unwanted work.
Therefore I suggest you purchase a tiny USB stick (USB3.0 32GB say) and install to that.
Then just press Ctrl L every time you boot safe in the knowledge that if you accidentally press space it won't matter :-)
