New Linux user here, with a Lenovo laptop that came with Fedora. On powering on, the machine initialized, and then created a user account with minimal user input. There were no startup dialogs on partitions or encryption. After messing with the box for a couple of hours, there was additional software I installed and some files I downloaded. So it would be inconvenient to lose that data, but it wouldn’t be the end of the world.
What I did not do was encrypt the user data portion of the drive before getting started with other matters. What I’ve found about encrypting indicates that the process results in data loss on the encrypted block.
Is there a way to encrypt while preserving the existing data?
