formatted to get rid of old files previously used. This can interfere with
installation in that not all files are transferred from the iso image to
the hard disk.

You can use the live USB to boot up to repair/install missing parts of the
system using the chroot method. I did a post on this in July 2010 when I
was having problems with GAG bootloader and GRUB2 on a Ubuntu derivative.

http://mailman.lug.org.uk/pipermail/dundee/2010-July/007896.html

In a terminal of the live system:

$ sudo mount /dev/sdX /mnt/boot (where sdX is your partition e.g./dev/sda)
$ sudo mount --bind /dev /mnt/dev
$ sudo mount --bind /proc /mnt/proc
$ sudo mount --bind /sys /mnt/sys

We will do a chroot now:

$ sudo chroot  /mnt

Update the system:

$ sudo aptitude update
$ sudo aptitude upgrade

For good measure, update the intramfs which I think is corrupted or missing:

$ sudo update-intramfs

To exit chroot press CTRL-D

Unmount the virtual filesystems:

$ sudo umount /mnt/boot
$ sudo umount /mnt/dev
$ sudo umount /mnt/proc
$ sudo umount /mnt/sys

Reboot:

$ sudo reboot (or exit terminal and reboot from GUI)
