man, you guys are about lame and a half. if you would just READ each otherss posts you could actually accomplish something. Let me clarify the situation.
you can install beos in a BFS partition, but, it must be a primary partition and you must install beos 5 from the windows program first, then install beos 5 into the BFS partition from within beos 5. also, the beboot menu won't see win2k, but it can, just enter it manualy, also, you can bypass the win2k boot menu by simply deleting the boot.ini file from the c: root.
