Thanks Greg
I also just spotted another error:
title Debian GNU/Linux, kernel 2.6.8-1-386 (on /dev/hda7)
root (hd0,5)
kernel /vmlinuz-2.6.8-1-386 root=/dev/hda7 ro
initrd /initrd.img-2.6.8-1-386
savedefault
boot
should be (hd0,6) - I typically play with these things late at night
... I claim diminished responsibility. Good job I haven't needed to
boot into my reserve system.
Cheers
Clive
