I am using Ubuntu 14.04 LTS along side Windows 7. I am trying to log into Ubuntu, but can't pass boot screen, doesn't matter how long I wait.
The problem started when I installed a series of software and tried to restart the system. The software were requirements of a course and are listed under title Software available through apt-get and Software available through easy_install in the following link:
