mount the partition of your install. Either mount it via command line if you know how, or just go up to places and select it there. If you do the later, it should mount to /media/a whole bunch of numbers and letters (for example, /media/123xyz)

then run

chroot /media/123xyz

then

apt-get install ubuntu-desktop

then reboot (and cross fingers lol)

You have to chroot into your install in Live CD. (chroot means to be in root of file system)
I will use sda5 for this you change to what yours is.

sudo fdisk -l

(will tell you your sda#)lower case L
Now in Live CD with internet connection:

sudo mount /dev/sda5 /mnt && sudo mount -o bind /dev /mnt/dev && sudo mount -o bind /dev/pts /mnt/dev/pts && sudo mount -o bind /proc /mnt/proc && sudo mount -o bind /sys /mnt/sys && sudo cp /etc/resolv.conf /mnt/etc/resolv.conf && sudo chroot /mnt

apt-get install ubuntu-desktop

exit

sudo umount /mnt/dev/pts && sudo umount /mnt/dev && sudo umount /mnt/proc && sudo umount /mnt/sys && sudo umount /mnt

Reboot into Ubuntu install on HDD.
