Presuming that you've diligently recreated your partitions, and copied them 
over, the only thing you'll probably need to do is run

/sbin/grub-install /dev/sdb

This presumes that your new disk is attached as /dev/sdb, and your boot 
configuration remains unchanged.

My recommended approach to copying one partition to another is using tar:

tar cf - . | (cd /new/mountpoint; tar xf -)

Although, I must admit that I have not done this since Fedora acquired 
selinux, and extended attributes. Perusing through the man pages, I'd 
suggest using "star -xattr-linux" instead of plain tar, in order to get 
everything copied over.
