I have Ubuntu 16.04 running on my machine, but for some purposes I need to install Windows. I like Ubuntu, however, and I wanna use it as my prior OS. So what I want to find out how to do is - how to install Windows 10 in dual boot os whilist keeping my Ubuntu 16.04 and how to ensure that Ubuntu is the default boot option? Also, is it than possible to make them each get access to only part of my hard drive? I got only one hard drive and I want each of them to use seperate disk part and not overlap.
So how do I do this all?
