install FreeBSD 8 on disk where windows7 made a gpt

[Nenhum_de_Nos]

hail,

I have Windows7 alone in a disk, and now I'd like to install FreeBSD 8 on
it. when I boot from USB disk, the partitioner says there is no partitions
on it.

then I read about: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot and got to
the fixit part. then gpt show ad10 says also there is no gpt in there.

is there any way to deal with this ?

thanks,

matheus
