making boot from previous internal drive now external work

Right, a bit of background.
Until about 3 weeks ago I had a Toshiba Laptop and I had it on dual boot
with Windows XP and Hoary Hedgehog.
Unfortunately the laptop expired and so what I did was remove the hard
drive, put it in a little "caddy" and it is now an external drive -- all
well and good! :-)
I have now got a new laptop and left the drive connected last night and
this morning when I booted up the screen said "GRUB" and hung.
I quickly realised that it was trying to boot from the external drive,
and that got me thinking. I would really like to try booting into the
external hoary from this new laptop. It would be a great solution to my
wife's reluctance to let me dual boot her new "toy" (I'm currently
running Warty in VMWare but that is not ideal).
Now, I'm sure it must be quite easy to modify the boot record on the
external drive to go straight into Ubuntu (or via GRUB - not an
issue)... to my way of thinking there are two problems at present...
a) The boot record on the external drive presumably instructs grub to
look for its config at a location which is currently the internal drive
in the new laptop. So that needs to change.
b) The grub config on the external drive will presumably also refer to
physical locations that are inside the new laptop.
So we presumably need to modify the boot record and modify the grub config?
Anybody here got any advice on doing this? Help would be much appreciated.
