Hi Guys,
So, I have an arduino uno r3 (not wired to any thing) but when I try to upload any sketch (even an empty sketch) first it takes too long in "Uploading..." then it comes with this error:
Arduino: 1.8.0 (Windows 10), Board: "Arduino/Genuino Uno"
Sketch uses 444 bytes (1%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
I have tried the loopback test and I checked that I have the right board it Tool/Board and the right port in Tool/Port
