Thanks for the confirmation although I never think in terms of having a
portable drive as
all mine are fixed in place. Your second para just lost me(bios
tweaking and pre-boot) as did
your reply about update-grub and reason why I didn't reply. One thing I
need to do sometimes
is read up on grub2 and have retained a post where a link info was
mentioned. Grub-legacy
was simple enough for me and always just worked; thank goodness grub2
just worked on my
two karmic beta installs and required no interaction on my part. Your
needs and interaction
go well beyond my needs and understanding so keep up the good work.
