On 15 August 1410 at the age of 11, she married Charles, Duke of Orléans (left an orphan by his father Louis's assassination in 1407). This marriage made the constable not only Charles's father-in-law but also the natural defender of both Charles and his mother Valentina Visconti. The Orléans party, decapitated by Louis's death, thus became the Armagnac party, the name it held right up to the treaty of Arras (1435).
Following the French defeat at the Battle of Agincourt on 25 October 1415, her husband was taken prisoner by the English. Bonne had not borne any children prior to his Charles's imprisonment. She died, childless, sometime between 1430 and 1435 while her husband was still in captivity.
