I have Grub in MBR.  To boot to Windows, Grub should put a Chainloader to
the partition where Windows is located.

For the Windows entry:

root (hd0,0)
chainloader +1

this boots the windows Multi-boot loader (Please select the operating system
to start)
which selects among the Windows installations.  I believe that this should
boot your Windows if it is the only Windows on your disk.

This is the way I have it setup, altho there are probably different ways to
setup multi-vendor booting.
