First off, don't worry about slice vs partition - Jerry was just telling  
you those are the names used by FreeBSD and Windows, respectively, for the  
same thing.

Second, how to get your dual boot going -

1. I think if you do what you've already done in FreeBSD (set the Windows  
slice/partition bootable) and then type "w" to write the change, that  
should work.

If it doesn't, two other alternatives -

2. If you have a Win9x emergency boot/system floppy hanging around, use  
fdisk to set the Windows partition/slice active, then reboot; or

3. Install GAG, a free, easy and automagical boot loader.  <URL:>.

Hope this helps,
