I've seen this before 5.0 release and made some investigation of this 
I didn't look this thread carefully so excuse me if information I give 
to all you is useless.

My investigation show that FreeBSD reads full partition table, and after 
puts it back. It fix all entries from its own point of view. Windows 
dies from change
of end of partition entry. As I understand with large disk it shouldn't 
mean anything
at all. But windows checks it. You may save this entry and after 
installation of FreeBSD
put it back.
