When i install multi-boot machines, i prefer to use GAG boot manager.

http://gag.sourceforge.net/

It installs itself on the MBR (it's tiny) and all you have to do is tell
Linux to install its boot stuff on its own partition.

As for Winblows, it always wipes the boot record and replace with its
own crap.  No problem, let Winblows install itself and after everything
is done, just re-install GAG, configure the menu items and you're all set.
