Nice article. Did you try using qemu. Its also simple to use and works like breeze for Windows 2000.

Assuming you have Windows 2000 CD iso image as win2k.iso
Steps
- Create the image file to store the installation. This image file will act as a hard-drive partition for the installation.
$ qemu-img create -f raw win2k-install.img 2G

- Now boot from the cd image
$qemu -hda win2k-install.img -cdrom win2k.iso -boot c -m 350 &

- After installation, since u no longer need the cdrom image
$ qemu -hda win2k-install.img -cdrom win2k.iso -boot c -m 350 &
