Just guessing, but from Jay's comments above and the way grub menu.lst
is setup, the boot point is something like hd(3,4).  This is where it
expects to find the kernel image.  If it can't it stops and looks for
help.  The removables will confuse it if they change.

Are you pointing to the /boot partition if it is different from the
root partition?
