Before we start, you have to tell us what you want as your bootloader to  
boot up your OS's, otherwise you'll end up with all the OS's installed and  
nothing can be booted. Also I assume you have not installed FreeBSD yet as  
you said "I want to install FreeBSD".

The easiest way is just to install FreeBSD and let that override the  
Ubuntu grub (assuming you want FreeBSD bootloader to boot). Just make sure  
you installed the FreeBSd bootloader and set that "to mbr". Then when  
FreeBsD is installed, assuming you're keeping Ubuntu as one of your OS  
(otherwise do nothing), boot up Ubuntu and at terminal, sudo  
dpkg-reconfigure grub-pc and set to sdxy, where sdxy is you ubuntu  
partition.
