I have Ubuntu installed in my system. I just installed FreeBSD 10.0 in to my system.Here is the screenshot of GParted.   Where /dev/sda1 is where my Ubuntu is installed, and /dev/sda4 is where I install FreeBSD. NOTE: Installation of FreeBSD is clean.But when I restart the system, all the time it is starting Ubuntu only.
unable to boot after installation : freeBSD
