I would think that the appearance of the above menu, and the fact that
it functions correctly when you choose FreeBSD indicates that the MBR is
would presume, then, that the Windows partition has been damaged.
If the file system the Windows partition is healty in general with just
a few files
in the boot sequence being damaged or missing you should be able to
Windows in that partition and find all your data and applications
present and in
good shape. If however the filesystem in the Windows partition is
messed up you
may have lost everything.
If you do re-install windows it will probably replace the MBR that is
what Windows consideres to be a 'standard' MBR. I think you can use dd to
copy the MBR that is currently there.
Then to get back to FreeBSD you'll have to use fdisk to set the active
to FreeBSD. Then you can, hopefully, restore the MBR you saved.
