I have installed
Ubuntu 16.04 in my whole laptop space. But right now , i have a requirement to install Windows in the same laptop. And since i am trying to install windows side by side with this Ubuntu version i tried to partition the hard drive space the current Ubuntu is installed in. However, i cannot partition the drive. So is there any way to do that?
P.S. I already tried using
disk-utility but neither of them seems to work.
