How to solve this problem？it happens on the UNO R3

This error might be caused by having the wrong port selected from the Tools > Port menu in Arduino IDE.
Please perform this experiment to verify that the port you have selected is your Arduino board:
With official boards, the port will be labeled with the board name in the menu (e.g., "COM42 (Arduino Uno)"). In this case, you can be fairly confident that you have identified the port. Select that port from the menu and try uploading again.
With some cheap derivative boards the port will not be labeled. You can positively identify the port using this procedure:
Disconnect the USB cable of the Arduino board from your computer.
Select Tools > Port from the Arduino IDE menus.
Take note of the ports, if any, listed in the menu.
Close the Tools menu. The ports list is only updated when the Tools menu is re-opened, so this step is essential.
Connect the Arduino board to your computer with a USB cable.
Select Tools > Port from the Arduino IDE menus.
Wait a few seconds for Arduino IDE to recognize the connection.
If a new port appeared at the last step, that is the port of your Arduino board. Select that port from the menu and try uploading again.
If the upload still fails, or if no new port appeared after you plugged the Arduino board into your computer, please reply here on this forum thread with the answers to the following questions:
Did you see a port appear in the menu after you performed the instructions?
If a port did appear, but the upload to that port still failed, what was the error message from the upload?
yes, i did it as you said, but this still happen when i burn the bootloader. the port is right and the computer can find this port , but the board could not pass the loopback test . so is the serial port normal?
This procedure is not intended to solve the problem. The purpose is to gather more information.
