PS:

IIUC this only happens to your Ubuntu 14.04, so after booting 14.04 and
running the above commands you can boot your 15.04 by running
  sudo shutdown -r now
and access the files in your 14.04 /home/user_home and post them here.
The shutdown command likely doesn't need sudo, but it might need root
privileges. Running it with sudo doesn't harm.
