I would like to thank all the replies to my initial message. Unfortunatelly, the firmware was an old one that didn't allow me to go into a config menu. I also made sure to jumper the boot0 and Vcc.
In the meantime, I had a great assistance from Igor, PY3IG, who told me to install the proper Win10 driver. Once done, everything else went smoothly. My hats off to Igor for his assistance and Youtube videos.
