Hi Phil,

I understand you need in the grub menu an operating system other than
Ubuntu to be on the first entry.

Here is a part of my /boot/grub/menu.lst file:

title           Ubuntu 7.10, kernel 2.6.22-14-generic
root            (hd1,5)
kernel          /boot/vmlinuz-2.6.22-14-generic
root=UUID=25420f85-4693-400c-a595-a3088a7c0144 ro
initrd          /boot/initrd.img-2.6.22-14-generic

title           Microsoft Windows XP Professional
root            (hd0,1)
savedefault
makeactive
chainloader     +1

Now, suppose you want the Windows install to be on the first line in
grub - you'd just have to invert the two entries to make menu.lst look
like this:

title           Microsoft Windows XP Professional
root            (hd0,1)
savedefault
makeactive
chainloader     +1

title           Ubuntu 7.10, kernel 2.6.22-14-generic
root            (hd1,5)
kernel          /boot/vmlinuz-2.6.22-14-generic
root=UUID=25420f85-4693-400c-a595-a3088a7c0144 ro
initrd          /boot/initrd.img-2.6.22-14-generic

HTH,

Alex.
