You'll notice bsdinstall has overwritten the MBR without asking any questions during the install, so for a scary few minutes you won't be able to access Windows.
Login to root (or login with a user and su to root), and then bearing in mind you should replace 'ada0' with your HDD's device if different, execute
boot0cfg -B ada0
to install the bootselect code to the MBR.
