Welcome to the forum

As your topic does not relate directly to the installation or operation of the IDE it has been moved to a more relevant category of the forum

If you are using an Arduino Nano then what have you got the Processor set to in the IDE ? If yours is a clone board then try setting the Processor to "Old Bootloader"

If you are not using a Nano then please give more details of your hardware

  • There are a few Arduino Unos; which one exactly? A link can be useful.
  • Anything connected to the board (specifically pins 0 and 1)? If yes, disconnect.
  • Did you select the correct board?
  • Did you select the correct serial port?
    Does that port disappear from the IDE when you disconnect the board?
  • What is the serial-to-usb chip on the board?
  • Which operating sytem?
  • What is the history of the board?
    New board?
    Did you ever manage to upload anything to the board? If yes, what was the project that you were working on when it started failing?
