[LBo] Setup grub to boot off external harddisk

[David Roseman]

Hi,

Thanks for all your comments - I think i need to do some more reading on how
grub works though.

In answer to Anitas question on why I want to do this, the reason is that my
windows install is sitting on my smaller 80Gb HDD internal and I have a
160Gb external.  I would like to shift windows to that and utilise the 80Gb
for another linux distro for experiment.

I would have removed it entirely, but the OU course I have just started has
materials which only work on windows.., oh and MS FlightSim X, if only
flightgear could begin to approach it, that would be fantastic.

Dave
