Inside Job

Inside Job is a Minutemen main quest in Fallout 4.

Detailed walkthrough
Once you are teleported into the Institute, go forward until you reach a terminal. It should be facing the opposite way of the direction you came in through. Access the terminal and insert the network scanner. Pick the option to scan the network, and after the scan is complete, the holotape should automatically return to your inventory upon leaving the terminal. Now, all you need to do is return to Sturges back in Sanctuary Hills. Note that you will not be able to return to Sanctuary Hills before scanning the network at the Institute.

Bugs

 * Proctor Ingram may not give the holotape back. On PC Version a fix is to open the console, click on Proctor Ingram and type "drop 136331 1" to force her to drop it out of her inventory. it is possible for console users to pickpocket to retrieve it..
