There's 2 types of PC boot CDs I believe, FreeBSD changed to the
newer method in last year or so I think (maybe just for 8.* ?), so
if yours is an older PC it might be looking for the other sort. You
could try a few years old (eg 6.* or probably 7.*) FreeBSD CDROM
for interest to see if that boots.

Question not clear.
You can access to read & execute all files from CDROM, by using the LIVEFS
(live file system) option.
To access files on the MS partition[s],
If fdisk shows the MS still present you can also mount the MS file systems from BSD (regardless whether BSD is booted & running from CD or hard disk)
For that you would need either
mount -t msdosfs ..... if its an older FS or
mount -t ntfs -r ..... if its a newer NTFS
it only support read only mode,
That mount command calls eg
/sbin/mount_msdosfs
/sbin/mount_ntfs
Thats where they are on a hard disc.
If FreeBSD hasnt installed yet, you'll find them I recall under
something like /mnt2/sbin/mount_msdosfs
(I think the cd is already mounted)
If you want to write individual files on an MS NTFS you need ntfs-3g
which is partly broken (one error noted in my
http://berklix.com/~jhs/hardware/laptops/shrink/
& a lot easier to run from a hard disk working system.

Well if you just wanted to trash the MS & not recover data ?
that's easy, the fdisk within BSD install should do it,
but you could always try something like
dd if=/dev/zero of=/dev/ad0 count=1000
DO NOT TRY THAT ON ANY SYSTEM WITH ANY DATA YOU VALUE
