Talk to Sturges
After receiving the quest from Preston Garvey, head back to Sanctuary (or to whichever settlement you assigned Sturges to) and talk to Sturges. He will inform you about a secret passage that could help the Minutemen enter the Institute.
Find the Public Works Maintenance Area
The secret entrance to the Institute can be found in the Public Works Maintenance Area, located in Cambridge. To locate it, you'll need to dive down east of the bridge and navigate through the kelps until you find an opening in the walls.
Activate the Keypad
After entering the Public Works Maintenance Area, be sure to activate the keypad on the right before descending down the pipe on the left.
Navigate Through the Pipes
After dropping down from the pipes, continue navigating the tunnel to the right until you reach an open pipe. At the end of this pipe, there will be an opening leading to another path and exit from there.
Hack the Locked Door
From this path, follow the arrows on the pipes until you reach a locked door that needs hacking to unlock.
Behind this door, you'll find an office with two Synths inside the room to the left. Defeat them, then enter the pipe below the platform to access the Institute.
Hacking Explained: How to Hack Terminals
Teleport the Minutemen to the Institute
Next, teleport Preston Garvey and the Minutemen using the terminal. To do this, load the Institute Relay Targeting Sequence Holotape and simply wait for them to arrive. Once they're all present, speak to Preston Garvey before proceeding.
Go to the Bioscience Department
To get to the Bioscience Department, head to the main square of the Institute, then into an old laboratory in the Robotics section. Afterward, open the hatch and drop down to the Bioscience department.
Enter the Main Square of the Institute
When you reach the Bioscience Department, take the path to the right until you see a Gorilla enclosure. Move to the left of the enclosure to find a small hallway that will lead you to the main square of the Institute. Exit the department from here.
Disable the Security of the Institute
Once you're in the main square, defeat all the enemies, including the Courser, to freely use the elevator in the middle. This will take you to the Father's room, where you can access his terminal to disable the security of the entire Institute. You can find this terminal on the second floor of his room.
Issue an Evacuation Order (Optional)
While you're at it, you can also issue an evacuation from the same terminal used to disable the maximum security. Simply select the first option to complete this objective.
Once you're done using the terminal, all doors should be unlocked. However, this also means more Synths will be deployed to attack you.
Place the Fusion Pulse Charge on the Reactor
Head to the Advanced Systems Department to find the reactor. The path towards the reactor is straightforward, and you won't need to take any turns, but it will be filled with turrets and Synths, so approach with caution.
At the very end of the path, you'll find the Reactor in a large room. Defeat all the Synths and Coursers here to safely approach the reactor. Once ready, plant the Fusion Pulse Charge and then find Preston Garvey immediately to teleport back to the circular room.
Talk to Shaun and Sturges
Once you return to the Circular Room, speak with Shaun and Sturges before teleporting outside to the detonator.
Detonate the Reactor
Once you're outside of the Institute, you and the rest of the Minutemen will be teleported to a nearby building with the detonator. Press the button to finally destroy the Institute.
Talk to Preston after Destroying the Institute
After the cutscene, speak to Preston Garvey again to complete the quest. You can also visit Sturges after this quest, and he'll reward you with the Short Automatic Laser Musket for helping the Minutemen take down the Institute.
