When I start my computer, it shows me a list of three options: "Ubuntu", "advanced options for Ubuntu", "System Setup" and when I click on Ubuntu to start the screen in most cases just turns purple for a indefinite period of time and in a very small percentage of cases it boots normally.
What's my problem and how can I fix it?
