I was attempting to install some Kali linux tools onto my computer running Ubuntu 16.04 using katoolin, and the majority of it worked out and installed properly, but when I tried to upgrade it an error came up. Eventually after some tinkering, the available updates from katoolin disappeared. Now when I boot Ubuntu does not even show up as Ubuntu, it says Kali Linux on the GRUB menu instead. I am not sure how to go about attempting to solve any of these problems as I am pretty new to Linux, so I was hoping someone out there could help.
Also, as of now GNOME is not loading, so I am at the stage of using a virtual console (I got there by pressing Ctrl+Alt+F1).
