I was recently told that uninstalling Gnome Essential Components (gnome-core) that it wouldn't adversely affect how Ubuntu starts. Unfortunately, after I uninstalled "gnome-core", my system restarted and won't load ubuntu. After grub, it just sits at the ubuntu screen and won't actually load up the os.
Is there a way to reinstall Ubuntu without losing any of my data? Is it as simple as popping in an install disc?
