Port not found

I tried uploading a code on the uno itself and it shows me the same error it did for the YUN. And the port still can't be selected but the lights of the arduino is on as usual

Error:

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with

option enabled in File -> Preferences.
