Maybe, if you don't understand what I said or don't want to research the stuff, Linux isn't really for you.

I would do a video tutorial but I think my explanation is good enough... I am getting a new laptop soon and I will try and install osu! on there, too. I will make note of everything I do from a fresh Arch install.
The 5 stuff in my post I wrote in brackets, you must type them in a terminal, but please research all the commands I posted so you don't do anything silly - in particular, 'rm -rf ~/.wine' will remove your entire Wine prefix.
For those Arch users, I realised there is an "osu!" package on the AUR (https://aur.archlinux.org/packages/osu/). I haven't tried it, yet.
