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

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Sooo... What happened? What did you do? Does the board type show up in Tools > Devices? Did you look at the steps at the link in the log?

I start Arduino program then I open the file code (.ino) then I click on upload button and I had that error. And the port menu is always gray, I don't know why. And the link in the log doesn't help me with my problem.

What arduino are you using? Also, I meant Tools > Serial Port.
