Select the port of your Uno from the Tools > Port menu. If that menu is grayed out or the port of your Uno does not appear on the menu, you might have a defective or charge-only USB cable. Make sure the cable is plugged in completely to your Uno and the computer. If that doesn't help, try another cable.
