Arduino: 1.8.3 (Windows 10), Board: "Arduino/Genuino Uno"

Sketch uses 1154 bytes (3%) of program storage space. Maximum is 32256 bytes.
Global variables use 11 bytes (0%) of dynamic memory, leaving 2037 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.

Problem uploading to board. See for suggestions.

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

First, is it a genuine Arduino / Genuino? Or a clone that uses the CH340 interface chip? If the latter then you need to locate and install the necessary drivers.

Are you sure the device is on COM1? I think that unlikely. The way I test is to remove the Arduino, then open up the port selection menu. Note any ports that show. Now connect the Arduino and repeat. The Arduino is connected to any new port that appears.

It's better if you post a picture of the board.
You may try another cable before you do something with the board.
