    the link is a complete how-to on installing grub customizer.

    Grub Customizer will let you change many settings in grub.

    If you do not want an easy gui, you can just modify grub's settings.

    Use command line editor grub's on set gfxmode=640x480
    and just remove the # as that makes that line a comment to default to 640x480.
    OR Use this with your monitor size in /etc/default/grub:
    GRUB_GFXMODE=1024x768
    Change above to exactly your video setting or you may have issues booting.

    sudo nano /etc/default/grub
    or
    gksu gedit /etc/default/grub
    # then
    sudo update-grub
