    I made these simple changes to my Lucid Grub 2 bootloader and am now a very happy Ubuntu dual booter. i mainly wanted to see the splash image I had for Karmic plus a descriptive boot menu entry. This is of course not possible when using the OS prober, which I disabled for good measure. Bootable rescue CD works fine as usual.
    (..Karmic is on my second SATA drive i.e. sdb with Grub installed to / partition boot sector, hence (hd1,1) ....)

    Changes made to Lucid (17-5-2010)

    In /etc/grub.d 40_custom added:


    echo "Adding custom boot entry(s)" >&2 (Edit: Not needed)
    cat << EOF
    menuentry "Ubuntu Karmic 9.10" {
    set root=(hd1,1)
    chainloader +1
    }
    EOF

    ***************************************************************************

    Add to etc/default/grub

    GRUB_DISABLE_OS_PROBER=true (under GRUB_COMMANDLINE_LINUX="")

    and.. (Edit: If you have this situation:- Bootup/Plymouth.
    Users should experience a much faster boot however some users may experience problems with Plymouth after the nVidia graphics driver has been enabled. Users may experience plymouth using lower graphics resolution.)

    # The resolution used on graphical terminal
    # note that you can use only modes which your graphic card supports via VBE
    # you can see them in real GRUB with the command `vbeinfo'
    #GRUB_GFXMODE=640x480
    GRUB_GFXPAYLOAD_LINUX=1440x900 ****

    Save the file and run sudo update-grub


    **** I added this line. (Should be your monitors native resolution)


    For Windows/Ubuntu dual booters this seems to be the way to go nowadays:-
