This is a bit confusing. You didn't tell us exactly what you did with
gparted (by the way, you should be able to do this with gpart(8) in
recent versions of FreeBSD), what version of fdisk you used, or what
MBR you are referring to here (maybe a protective MBR?), since you
claim that Win7 only installs in a GPT scheme. Are you sure about
that? Did you try to layout a disk first, and then install Win7 into
an existing partition? I don't have a copy of Win7 to check this, but
I've seen other accounts that didn't mention this problem, e.g.,
But maybe you have an EFI-based system?

How exactly did you determine that FreeBSD doesn't "see" the
partitions? By using "gpart show"?
In the past, I've found:
a useful source of information about using GPT with FreeBSD and Win*,
although some of the OS-specific material is dated.
