Hi all, sorry to bother you all with this. I was using linux mate 18.3. On an Old Lenovo 500. I tried to upgrade to cinnamon but ordered Robo linux from the linux shop in error. Thought I would run it in compatibility mode to see if it might be useful. After it completed its checks the computer refused to restart in anyway. I cannot remove the disk. I would appreciate any possible solutions as I can't afford another computer right now.
