Check the output of

	# fdisk ada1

and

	# bsdlabel ada1s1

and verify that it reflects the layout and configuration
that you actually want. In worst case, erase the beginning
of the disk and initialize it again. If deleting disk content
is not an option - don't mind, installing boot code usually
does not affect "real" data.

Use MBR only if you have a specific need for it (which might
be possible). Using GPT is advised today, but MBR will work
in most cases - as GPT should, too, but other most cases. :-)

You can also use

	# gpart show ada1

to see if there is a GPT partitioning going on (which fdisk
and bsdlabel cannot deal with), just to be sure.

You have two (three) ways of disk initialization in this thread
and from the article of Warren Block. At least one should be
working for you. Choose wisely. :-)
