I took notice of what Brett said last week about not doing a backup of /dev so that should remain untouched from the install.
But now having restored everything, it comes up with the message 'No root device "block:/dev/disk/by-uuid/<disk-id here>" found and then 'resume device /dev/disk/by-uuid<another disk-id>'
It is probably because you have overwritten /etc/fstab and modern installations will have disks by uuid rather than by device name.
You could also fix it by editing fstab and either determining your UUID's for your current disks from the grub command line (sorry I forget the exact magic prayer) or replace the UUID= bit with the device of each specific partition (i.e /dev/sda1) as was done in the old days.
I'd also not overwrite /boot and perhaps not /etc/default/grub when you restore your backups.
