Assuming you mean Ubuntu 9.10, the following procedure worked for me: 1. Add the following four rows to your /etc/grub.d/40_custom, adjusting the "hd0,1" part to match your disk and partition numbers where your Haiku installation is located, in my case on the first disk (0) and the first partition (1)): menuentry "Haiku" { set root=(hd0,1) chainloader +1 } 2. Run 'sudo update-grub' in a terminal. 3. Unless you specified multi-boot during installation, the grub start menu is hidden by default. You can either press both Shift keys during boot to display it, or comment out row number five in /etc/default/grub (GRUB_HIDDEN_TIMEOUT=0) and running 'sudo update-grub' again. - luroh
