My guess is that a grub reinstall could restore your system. Try 
googling for "grub reinstall".

If you can run the Live CD, (desktop, not alternate) this means you have 
no hardware trouble and should be able to mount any partition from the 
Gnome Desktop, with "sudo mount". Any doubt please check "man mount".

As last resort if you still have unpartitioned space in one of your 
disks or can get some space by changing the sizes of the existing 
partitions you could always use this new space to install another 
instance of Ubuntu and from it access the rest of the system.
