I bought a new win10 lappy and have already started hating it. I want to go back to Ubuntu but some of my office tasks require me to have Windows, so I guess the only solution is to have my lappy dual booted.
I don't want windows10, So i am going to install win 7 and then dual boot it with Ubuntu.
I've never done this before so I need detailed guidance. Do I need to back up all my drives or just the C drive before installing Ubuntu?
