Public bug reported: I first attempted to upgrade 15.04 to 15.10 which failed half way through making a mess of 15.04. When I attempt to reinstall 15.04 from USB, it makes it to the grub install and fails.
I attempted to reinstall 15.10. It completed the install, but still does not work. Will not roll back to 15.04.
