Long story:
Tried to install Ubuntu 14.04 desktop. 12 already installed. Dual boot system with Vista.
Install failed. Now I cannot boot to either 14 or Vista. Grub rescue only prompt available.
Tried sudo add-apt-repsotitory ppa:yannubuntu/boot repair
. It could not find boot repair
Tried update
. No go.
Tried install
. No go.
Ubuntu will not install again either.
Desperately need to get windows back. Files system shows Windows system intact. Grub seems to be the issue.
