Crashed on installation, root directory established properly after formatting.

[Aamir Majeed]

I initially had ubuntu installed on the given partition, due to bugs with installing/deleting gnome on ubuntu, and the login/black screen error, I reinstalled using a USB boot loader. On installation, the GRUB installer crashed, leading to this bug.
