Hello! I just received a Raspberry Pi 3, and have just set it up, and I currently have a few operating systems installed on the device. However, I would like to install Ubuntu MATE on it as well. Initially, I was given a list of operating systems to install, but I didn't happen to see it on the list. Is there a way for me to install Ubuntu MATE on the Pi on the same SD card, without having to erase my currently installed operating system? Thanks in advanced!
