Does Windows Vista support VHD booting?

I just wanted to know, because I use Windows Vista now, and quite a few websites say that Vista can do VHD boot, but I can't find any options. Is there? Is there not?
If not, is there another way?

Welcome
Are you referring to something like this?

Er-- that's not really what I mean. I know there's a way to boot VHDs on a machine with Windows 7. I just wanted to know if it's supported in vista, and if not if there are any alternatives.
Thank you though.

Think I know what you mean, now
