New UNO (not a clone) will not load program. I am using IDE 1.8.13, Windows 10 pro 64. I am successfully using the same system to load a Mega 2560. I have enabled verbose compile and upload. The compilation messages look good. I get the following upload message:

Thank you. Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
The two error lines are repeated 10 times. I looked at the troubleshooting page and the only item that seemed relevant was the possibility of no bootloader. I noted that the LED on pin 13 does not blink when I reset the UNO. Does that mean that there is no bootloader?
