Make sure you have the right board type selected in Tools->Board. Also make sure you have the right serial port selected in Tools->Serial Port.

Hold the shift key down while you press the upload button and post the resulting diagnostic output.

What was the fix, because I'm having the same issue. So far all the other sites I checked just say it could be anything. If you could post your fix It would be great. :) Thanks!

Actually I just fixed it :P can't tell I'm new here. I just unplugged the USB from the PC (previously I had only unplugged it from the UNO. And pressed RESET on the board as well as restarted the IDE program. Not sure which one of those fixed the issue or if all of them did but I used the BLINK program as a test run and it's working fine now. Hope this helps anyone else who might be looking.

@tharun - Sounds like you have the wrong port selected. What OS are you using?

@Aman - Double check that you have the right COM port. Occasionally they get re-assigned by Windows.

Also - watch the leds on the Arduino. Do you see any flashing as it tries to upload?

If you press the reset button, do you see any flashing?

It sounds like the bootloader is working, but the usb/serial connection is not.
Let's try to rule out a few of the simpler possibilities first:
  • Try different USB ports. USB 3.0 ports can be a problem, so stick with 2.0 ports if possible.
    Try a different cable. (You would be surprised how often that is the problem!)
And what kind of Arduino are you using? Is it an UNO?
