not to say the same thing that everyone else just said..... but windows does like to be first in line. i've had some problems before with windows being installed second, as it has been know to install it's bootloader over lilo (bootman in one my cases, lilo in my linux outings) in the mbr and pissing everything else off.

by the way, booting from floppy into BeOS to re-install bootman is a freaking magic trick.

<edit>
also, if you do two versions of windows, like 98se and 2000, as well as linux, do 98 first, then 2000, then linux. 2000 has that little half baked bootloader which will allow you to keep things pretty easy,

Step 1: Windows or not?
Step 2: (if windows was chosen) 98se or 2000
