I was given a 8,2 15" MBP, and b/c its graphics won't allow me to install Mojave, I want to turn it into a dual booted Linux/Windows machine. (I'm a developer, and find myself needing to tread into both worlds more and more.)
I found this article to help with this... except I don't really need to keep a viable older macOS on this machine. Just Win7 (which I'm gonna quickly upgrade to Win10) and Ubuntu Desktop. How would you, after getting rEFInd installed, and Win/Linux installed, excise the macOS still there? Or is this even the wrong approach?
