Delete the first part of the disk (overwrite with null bytes),
for example using the 10.0 installation CD shell or a Linux
from disk (e. g. tomsrtbt):

	# dd if=/dev/zero of=/dev/da0 bs=1k count=1000

This erases the 1st MB of the disk. Any boot loader should be
gone now. As you're going to do a fresh install (if I read your
question correctly), this doesn't matter. The remaining garbage
on the disk isn't associated to a partition or OS anymore, so
you can create the new partitions you need and install the OS
without paying attention to what has been on the disk before.

Check "dmesg" output to verify which device name is associated
to the disk in question.
