I knocked up an old puter with two drives, one drive has Kumbutu and
t'other has Windoze Xp. I was hoping to molish a dual boot effort
The usual "duel boot" spelling is not entirely accidental. My favourite
ToBAGO.
Either drive will boot when alone on the eide cable. When I put the
Kubuntu drive as master and Win drive as slave grub comes up but there`s
no Winxp in the list.
If I put the winxp disk as master and the linux disk as slave, it boots
up windoze.
I'm new to this linux lark (I got entusiastic about it when I bought an
EeePc)most of what I read goes right over my head.
Number One son says grub should automatically find winxp and he goes to
uni and is never wrong, so where am I going astray?
I've been looking at grub recently, but I know nothing of the windows side.
So, each system is fine and okay on their own, it's that neither knows how
to boot the other, and needs telling ? So, 2 possible ways round :-
a) Set up the win to boot, and it might have some sort of bootmenu system that
could be told about a linux. The history of this is not good, it was
never very co-operative about such things in the past, and has at times had
a tendency to accidentally oopsohdearwhatashame damage "competing" systems.
This may, perhaps, have improved these days (as I say, I Know Nothing), but
I'd recommend ...
b) ... better bet, IMO, boot from the linux disk, which will then give you
the grub bootmenu. This is at least easy to deal with and well behaved
(linux utils are much better at dealing constructively with windowses than
vice versa) - it's controlled from (on the linux disk layout scheme)
/boot/grub/menu.lst which is a simple text file with lists of things you
could boot from and details of what happens when you do. Which is nice,
becasue you can go, eg, 'less /boot/grub/menu.lst' and get a look at what it
thinks it's doing. And adding/changing entries is just a matter of
$favouritetexteditor.
So, a hypothesis - an incantation needs to be found, to add to the grub menu
list, that would point it at the xp disk. If a right one could be found, I
suspect this would be all that's needed.
Anybody know what would be suitable details for a "XP boot" grub menu item ?
If not I'll come up with some guessjbex, but knollidge would be preferrable.
There is a GRUB manual online containing far, *far* Too Much Imformation.
it would be nice not to have to resort to it.

An afterthought. This glitch can sometimes be an artefact of the
installation order, is it possible that the grub installation & setup didn't
notice the XP because the linux was installed first so the XP wasn't there
for it to see ? It's usually a good idea to have installed windowses first,
and linuxen (linuces ? linii ?) afterwards, because, as above, they're
better at being cooperative than the monopoly systems. If that's how it
went, now that there is a windows present, it could be that removing grub
entirely and reinstalling it might just spot it and deal with it. OTOH, it
might not, or the linux might complain that it depends on it and doesn't
want to. Or it might just reinstall with an empty menu, in which case you'd
have to remember to have kept a copy of the original menu to put the
linux-boot option back in, or find yourself with no offers of anything to
boot next time you switch it on ...
