How to unlock the The First Step achievement in Fallout 4 - Definitive Guide
This is a story quest and cannot be missed.
Basically I finished "the first step mission" and did not get the achievement. All my answers to Preston were basically the "nicer" answers. Tried reloading with no luck. I was annoyed so I reloaded again and was basically a dick to him. I wish I remembered my exact answers but I told him maybe it would be better off without the minutemen and then something else and when it got to him saying yes or no, I said yes and immediately achievement pops. If you can save before you turn in to him you can try different dialogue options to findicate the right one. Hope this helps someone.
For now I saved the game right before talking to Preston, and I memorized its time slot so I'll probably continue the game and come back to it later.
I'll update if I ever get it to work, thanks though!
Quest Giver: Preston
Location: Sanctuary
You simply need to talk to Preston after returning with him to Sanctuary. He wants you to lead the MinuteMen into the new era. When you accept this role you will unlock Preston as a companion, the Minutemen questline, and this achievement.
Faction: Minutemen
Quest Giver: Preston Garvey
Location: Concord/Museum of Freedom
You will have the option to join the Minutemen very early in the game. When you are in Concord, you'll come across the Museum of Freedom and get the quest called "When Freedom Calls". Enter the Museum and kill all the raiders, now talk to Preston Garvey then go to the roof and get in the Power Armour that's up there. Fend off the enemies then head to Sanctuary with the Minutemen, where you will then get the option to join them. You can do this without fear of other trophies becoming locked out as you can work with all the factions at once.
