(Get the code!)
@ket I agree that this is frustrating.
You shouldn't have to reformat your disk to fix it, however. You should be able to plug in the device with your newly installed Ubuntu, boot up until you see the grub prompt asking you what system you want to boot, and then choose the old Ubuntu version on your hard disk.
The other alternative to reformatting is to boot from the install CD to make repairs.
Getting back to not having to plug in the old device involves changing a file on your hard disks efi partition, ubuntu/grub.cfg in order to point it back to the original disk partition you want to boot from.
