That's one of the reasons why there are special "ghosting" programs. I could be wrong, however, and "dd" will be just fine:
Anyway, this is what I'd try: - attach both harddrives to the Mini - install rEfit on the new harddrive - repartition the new harddrive - make filesystems to the new partitions - boot to Knoppix or some other Live-CD/DVD distro - mount the drives - do a "cd /your/old/root;cp -a * /your/new/root/" - create a chroot mountpoint to the /your/new/root/chroot - chroot /your/new/root/chroot - run grub-install That's it. Simple, eh... Of course if the problem is not cause by "dd", then this won't help, and is a bit complicated. But I've restored my Macbook's OS (Debian) this way when I had a messed up partition table, so I know it works.
