Kai: I am not using Windows Boot Manager. Grub comes up, as on the 2
boxes, where things are working properly.

Questions: (a) Can I copy /boot/grub/grub.conf on my box and replace
that file on my wife's box, with my version? Would that work OK? Worth a
try?

(b) Which files should I compare, between my box and my wife's box, the
problematic one, to see if I can locate differences?

There was confusion on my part, when I installed Windows XP on my wife's
box. Hers was the first one I installed Win XP on, which I'd never
installed before and it ended up getting installed more than once.
However, in general, I thought her box was the easiest, with regard to
the WinXP installations. There may have been some partitioning issues
also, since each box has 4 partitions on the Windows side (C, D, E & F).
In general, it is *much* easier for me to install CentOS than to install
Windoze. And, *much* faster.  :-)
