I use a GPT partitioning scheme for FreeBSD and Linux, and manually edited the protective MBR in order to declare MBR partitions on the same sectors than the GPT partition I wanted to use for Windows. Working really nice. There are tools like gptsync which are simpler to use than a low-level MBR editor.
