I played around without looking in terminal and I somehow started to erase all the ubuntu system files. Now all I want to do is access my photos and transfer them over to my portable hard drive but I can't do that using a LiveUSB with ubuntu or with the Boot-repair liveUSB.
My only option I understand is to reinstall ubuntu but I'm afraid that doing that it will erase both the system files and the other partitions files where my photos are.
