Arduino Uno not reading board

Hello!
I just bought a Uno rev3. When I try to upload anything to the board, I get this error:

Sketch uses 20988 bytes (65%) of program storage space. Maximum is 32256 bytes.
Global variables use 527 bytes (25%) of dynamic memory, leaving 1521 bytes for local variables. Maximum is 2048 bytes.

avrdude done.  Thank you.

Problem uploading to board.  See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

I read the section about my specific error, and it says it isn't finding my board. Entering messages into the serial monitor doesn't return anything.
I also tried reinstalling everything, no luck.

Welcome.

Does COM3 disappear when you disconnect the board? If not, it's not the Arduino.
Did you select the correct board?

Is that with the Loop-Back Test Instructions ?

When I disconnect the board, COM3 disappears.
And yes, that was using the Loop-Back instructions.

edit: when I upload and get the error, RX blinks 3 times.

Only question that you did not answer is if you selected the correct board :wink:

I seem to remember that there is something with bluetooth on a laptop but I can't remember the details :frowning:

Just to make sure, you see something like below in Windows device manager; COM8 will be COM3 in your case.

Yes, I have arduino Uno selected. It shows up just fine in devices.
edit: tried another cable. same thing.
