Also advancing to the quarterfinals were Shashi Chopra (57kg) and Jyoti Gulia (51kg).
Boro out-punched Turkey's Cagla Aluc in an aggressive performance to fetch a unanimous verdict in her favour.
Gulia, the boxer who opened the proceedings for India this afternoon, defeated Ukraine's Anastasiia Lisinska to make the last-eight stage.
Chopra, on the other hand, got the better of second seed Taiwan's Lin Li Wei-Yi to be just one win away from winning a medal.
