I already have Ubuntu installed, newest version I believe, and would like to dual boot Windows 7 or 10 (which ever is easier). Most the guides I find are for people who have Windows and want to dual boot Ubuntu, but is there a way to do it the other way around? All I can find is for the Windows to Ubuntu way and not Ubuntu to Windows.
I want to keep Ubuntu as my main OS and Windows as my secondary for video games.
I've been reading a bit though that this is kind of hard too do, as Windows doesn't like being a secondary OS.
Thanks.
