avrdude done. Thank you.

the selected serial port
does not exist or your board is not connected

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

I am having the same issue with one of my boards. The other two (it was a pack of three) work fine and upload perfectly, but I can’t get this on to work. I have also installed the drivers, and I know the board was functioning as it came preloaded with a blink sketch

See what Device Manager shows when you plug in the Nano.
It should be USB-SERIAL CH340 (COMxx), where xx is your port number.

Com port 8, try different port but still nothing, device manager show ch340 and com port 8 when unplug its disapear, so not this problem

Further.

And? I see this also

Still same error
