Has anyone done such a thing already?
sudo mount /dev/sdb1 old
sudo mount /dev/sda1 new
sudo cp -rp old/* new
sudo grub-install --root-directory=new/ /dev/sda
sudo fdisk -l
sudo mount /dev/sda1 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo chroot /mnt
(optional, only if you're on Ubuntu/Debian) apt-get install grub-pc
grub-mkconfig -o /boot/grub/grub.cfg
grub-install /dev/sda (try grub-install --recheck /dev/sda if it fails)
Ctrl+D (to exit out of chroot)
sudo umount /mnt/dev
sudo umount /mnt
