Hi there,

I tried to install FreeBSD on my MacBook. Bascially I followed this post online.
glenbarber.us - Dual Booting OS X and FreeBSD 9

And the tragedy happened. I do remember, as the post said, typed
gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 3 ada0

By the way, I did installed rEFIT on Mac OS

After rebooting, I see neither my Mac boot option nor the FreeBSD boot option. Even after holding Option key...

The only stuff can boot is if I insert a CD (say, the FreeBSD live CD)...

My installation was successful, but the boot loader was messed up!

How can I fix this?

Thanks!
Alfred
