I started my computer and walked away. Windows began it's diagnostics and when I returned I restarted at chose GRUB from my boot menu (I installed through WUBI)
Instead of loading GRUB as usual and showing me a list of my Ubuntus, it loads GRUB1.99ubuntu2.3 or something ridiculous like that (I have Ubuntu 12.04).
There is nothing available but a <grub> terminal and the option to press TAB for a list of commands. What the heck happened and how the heck do I get back into ubuntu?
