USED 2010 MacBook Pro 13 Inch FAULTY Start Up Disc

13 inch MacBook Pro. Bought brand new for $900 back in 2013. Used only for college and post-college for papers, projects, and editing. Boots up and holds a charge just fine. The Start Up screen (folder with a question mark symbol) shows up when powered on. Other than that, it connects to WiFi, all the keys work, the volume is clear, and the entire appliance is in a plastic case for protection. Probably good for parts, but will work great if the start up disc is cleared and rebooted.
