Triple Boot Win98se/winNT 4.0/win2k

Hello:
I’m trying to do triple a triple booting with win98se, windows nt workstation and windows 2000 professional. I need the three of them for testing installation packages. I’ve already installed the three OS on different partitions, I set the win98 partition active and primary, I installed BootMagic on it and configured it. When the PC boots, I can see the three OS options, there’s no problem loading win98 and winNT but the system gets completly lost when I rty to load windows 2000, any idea why this is happening? What is missing?
Thanks in advance,
Lizet
