Tried to install elementary OS the same way I used to before - Leave free space at the time of Windows installation and then just split it up during elementary OS installation. But now there's no options for it, at the begging in doesn't even offer side by side install (just option to delete Windows 10). Option of installation called "Something Else" gives me partition but doesn't allow me to split up "unusable" partition (+ and - buttons are greyed out). Why is it unusable?
Am I missing something?
