1. Grub and your mount command are having difficulty reading UFS2, the
new default filesystem for FreeBSD 5.x.  One solution is to choose to use
the "old" filesystem, UFS.  I have seen previous discussions here about
this topic; right now I cannot remember what was said, but you should be
able to find these messages with a search from <URL:
http://freebsd.rambler.ru/>.

2. If the steps you took in response to #1 prove insufficient, choose a
"normal" MBR (not the FreeBSD boot loader, not to leave the MBR
untouched) when installing FreeBSD.
