Add My-Link external optical drive to Lenovo iedspad s10

I have a Lenovo ideapad s10 running sled 10. I have been having some probs getting the gui up I have to startx each time I go in and it won’t shutdown so I wanted to load 11.1 - I have this on a dvd but cannot get the ext drive recognised and then need to know how to install 11. Some help would be appreciated.
