I have kept the referral to the old problem in the topic for a reason. Been there, done that. I'm not entirely sure how, but boot-repair was the only thing that was able to fix Grub. Before that I've reinstalled it countless times, thanks.
But since this is very much not an answer to the question at hand, but to the original question - and as such an entirely different topic - I'm rewriting this to the old topic too.
