I just bought a (refurbished) computer. I have done almost nothing on it and I would like to install Ubuntu from a live CD disk. However, I am getting the message: "This computer currently has no detected operating systems. What would you like to do?". Windows 8 is installed on the computer and works, but is not being detected by Ubuntu. I have read that this might be a consequence of partition tables, so I have attached a screenshot. What should I do?
Edit: For solution, see link in last post.
