CPU-intensive processing is exactly the kind of work that the BEAM is lousy at handling. Elixir would be a terrible implementation language for this kind of thing.
I had a x220 and it worked fine with Ubuntu in EFI-only mode. Same for my current x230. Probably boots 1 or 2 seconds faster because of that. But I never managed to get it working by doing the partitioning work myself (which I prefer because I don't like having everything in a huge partition), you have to format the whole drive and let Ubuntu do its thing.
