One thing I forgot to mention - make sure you change the setting for the splash screen as well. Otherwise grub tries to load it from the wrong drive and errors out. (I forgot once.) You then get the grub> prompt, and wounder why. You may also want to back up the mbr of your laptop hard drive before running grub-install. If you goof, you can end up with a system that will only boot with the USB drive installed. I use something like "dd if=/dev/sda of=/root/save/sda.mbr count=1".
