I don't have your exact problem, but i am sharing my laptop disk
between Windows, FreeBSD and Ubuntu and i have noted that grub2
which comes with Ubuntu Lucid can directly boot /boot/loader
un in UFS2 partition, son i suspect this could also solve your problem,
rather than chainloading. Here is the syntax:
### BEGIN /etc/grub.d/40_custom ###
# This file provides an easy way to add custom menu entries. Simply
# type the
# menu entries you want to add after this comment. Be careful not to
# change
# the 'exec tail' line above.
menuentry "FreeBSD (on /dev/sda4)" {
insmod ufs2
set root='(hd0,4,a)'
kfreebsd /boot/loader
}
### END /etc/grub.d/40_custom ###
Since i have played with grub a little, here are some other adaptations:
### BEGIN /etc/grub.d/05_debian_theme ###
set menu_color_normal=cyan/blue
set menu_color_highlight=white/blue
### END /etc/grub.d/05_debian_theme ###
to get more attractive colors (for my taste)
and in /etc/grub.d/00_header to get native screen resolution for the
laptop screen:
if loadfont /usr/share/grub/unicode.pf2 ; then
set gfxmode=1280x800 <---------
insmod gfxterm
insmod vbe
if terminal_output gfxterm ; then true ; else
# For backward compatibility with versions of terminal.mod that
# don't
# understand terminal_output
terminal gfxterm
fi
fi
Of course run update-grub afterwards. I have also seen in plymouth
Ubuntu documentation that one can
set gfxpayload=keep
just after set gfxmode
but it doesn't work for me.
