Expanded/Legends
Here Jango Fett lived with his parents and his big sister Arla Fett on planet Concorn Dawn, Death Watch led by Pre Vizsla killed Jango's parents for aiding the True Mandalorians led by Jaster Mereel and his sister Arla was kidnapped by Death Watch. Jango ran after witnessing everything that's happened until he ran into Jaster Mereel and his True Mandalorians whom he help defeat Death Watch in an ambush, Jaster then welcomes Jango into their ranks and adopts him.
Years later Jango is now a full fledged Mandalorian and squad commander under Jaster's tutelage on his first mission in Korda 6. The True Mandalorians battled the Korda 6 defense force and Death Watch who were also in the planet, Jaster himself was killed at the hands of Pre Vizsla, after this Jango banished Jaster's second in command Montross for leaving Jaster to die. Jango became the new True Mandalorian leader and Jaster's legacy.
On planet Galidraan the Governor hired the True Mandalorians to eliminate the rebels in exchanged of information on Death Watch's whereabouts. Unfortunately they were set up since the Governor followed Pre Vizsla's instruction and lies to a Jedi Strike Force led by Count Dooku that the True Mandalorians killed Political Activist. The Jedi Strike Force succeeded on wiping them out except for Jango who beats several Jedi to death with his bare hands before being subdued.
Turned over to the Governor who plans to sell him to slavery Jango was still able to escape and went after Pre Vizsla on his own. Jango battles Pre Vizsla and succeeded on killing him, with the True Mandalorians gone, Jango needed to make a living and started his career as a Bounty Hunter.
Sometime before the events in Attack of Clones, Count Dooku under the instruction of his master Darth Sidious put up a special hunt for Dooku's former pupil Komari Vosa for the perfect candidate for the Clone Troopers. Both Jango Fett and his nemesis Montross would 2 perfect candidates for hunt, the hunt ventures on Corusant, Oovo 4 where Jango found his new ship Slave I after his old ship Jaster's Legacy was destroyed and met Zam Wesell. The hunt continues on Malastare, Tatooine before coming to an end on the moon of Bogden but not before making a final farewell to Rozatta who dies because of Montross.
Along the way Jango battled Montross 3 times and the third time Jango defeats Montross who wishes for a warrior's death, but in Jango's way of revenge for leaving Jaster to die and the murder of Rozatta, Jango allows the Bando Gora to rip Montross apart. Jango finally confronts Komari Vosa and defeats her before she was killed by Count Dooku who tells him about the army of Clone Troopers, Jango accept the offer as long he has the first clone for an apprentice for him who will be name Boba Fett who will be his legacy after his death at hands of Mace Windu in Attack of the Clones.

Canon
Here Jango Fett's home world Concord Dawn probably is near planet Mandalore, unlike the Expanded/Legend, since it's unknown how he got his Mandalorian armor because the True Mandalorians doesn't exist in the Canon and it's unknown how he got Slave I too. Still where Jango Fett met Count Dooku is the same location of Bogden but he never battle Komari Vosa in the Canon.
During the events in Star Wars: The Clone Wars in the episode the Mandalore Plot, when Obi-Wan was speaking with Prime Minster Almec, he mentions his encounter with Jango Fett but Almec dismisses Jango if had any ties with Mandalorian Culture since he only sees him as common Bounty Hunter and how he got the Mandalorian armor is unknown.
Boba Fett on the other hand, still a young boy desires revenge on Mace Windu and avenge his father with a little help from other Bounty Hunters. His plan to assassinate Mace Windu by planting a bomb hidden on Jango's Mando helmet failed.
End
I've seen many Star Wars fans who were not too happy about the change of Jango Fett's story in the Canon. I saw that on youtube comments, anyway coming up next is still not chapter.
