In Vista the way that Windows start changed. The MBR points to a file 
inside the Windows partition that have the partition scheme. It's 
called BCD. You can install EasyBCD in windows (it's freeware with 
commercial licence) that permits you to start Windows and other OS 
inside other partitions. I use it in my trial? 
Win7/FreeBSD8.2/OpenBSD4.9 server and dual Win7/FreeBSD8.2 laptop.
