My pc dosen't recognize this board. I have tried to bootloader it, but isn't working. I need to buy another one? Or exist a solution?I will upload an image when it is connected to the pc!

By "doesn't recognize", do you mean that you don't get a COM port for your Uno when you plug it into your computer? If so, burning the bootloader will not help with that problem.

See what you can discover by running Windows Device Manager.

Once started, open the tab "Ports (COM & LPT)". Is your device listed?

NO

This is how my UNO is listed under the Ports tab (it doesn't actually say "UNO"):

"USB-SERIAL CH340 (COM 9)"

Unplug the UNO and replug it. Does Device Manager react or remain unchanged?
