Windows boot loader to boot others OSes.

Came across this post regarding the above. However, while the post only covers booting Ubuntu and Windows Vista, on my Dell Dim 9200 I have Windows Vista, Windows 7, Ubuntu, FreeBSD, Haiku and an i86 version of OS X.
As suggested in the post, I used EasyBCD (which is very useful) to create the boot menu. Including the Windows OSes and Ubuntu was easy but all of the other three gave problems.
Although, a section is included for booting what it calls "Linux/BCD", I couldn't get FreeBSD to boot using this. Nevertheless, when I classed FreeBSD as a Mac-type OS (booting from EFI), I got the EFI boot screen which after hitting "any key", FreeBSD proceeded to boot.
I really have no idea why, however.
Nothing that I did could induce either Haiku or OS X to boot directly from the NTLoader menu. But, if I classed them as Linux OSes, then the boot menu associated with Ubuntu showed up from which I could select either one.
Nothing very exciting here, but I like to experiment.
