Problem booting FreeBSD 10-CURRENT from my MacBook Pro: "Can't load kernel"

Hi, everyone and good morning! To make a long story short I'm attempting to
install 10-CURRENT on my 2011 model 17 inch MacBook Pro. I downloaded the
appropriate amd64 image from FreeBSD's FTP site, burned it out to DVD and
installed it on my old FreeBSD 9 partition, erasing existing data. However,
when I try to boot the new system, I get a "can't load kernel" error. Giving
the command "ls" returns the message "Open '/' failed: no such file or
directory". 
When I type "lsdev" the following is returned:
"cd devices:
disk devices:
        disk0: BIOS drive C
pxe devices:"
I can work around the problem by copying /boot from the FreeBSD 9 installer
to my new FreeBSD 10 system, but I do believe this is not the right
solution? And when I then boot off the system, I get a lot of other system
errors. 
PS: my Mac does not have a real BIOS, so changing any BIOS settings is
unfortunately not an option.

I hope you can help me out and thanks in advance.

Have a great day, everyone!
Best wishes, 
Anders
