That should not be much of a problem if your system is MBR+BIOS. If your system is MBR+BIOS, the following should work. Boot with your FreeBSD CD/DVD/memstick, and write out boot0 to all your disks: boot0cfg -B /dev/<disk0> boot0cfg -B /dev/<disk1> boot0cfg -B /dev/<disk2> Next, boot with your Ubuntu CD/DVD/memstick, and write out Grub to your Ubuntu / partition. If Ubuntu / is /dev/sdb2 : sudo mount /dev/sdb2 /mnt sudo grub-install --force --root-directory=/mnt /dev/sdb2 Reboot. When booting Ubuntu the first time, first press 'e' at the Grub loader menu to edit the configuration, delete the complete if..fi block, check that your line beginning with 'linux' is accurate and then press F10. Once the system has booted, run 'sudo update-grub'. Hope this helps, Manish Jain
