I'm not too sure about windows 2k, but I'm pretty sure that when you boot it, you can change the boot options by pressing f12 (I believe. On quite a few manufacturers they show you at the bottom of the screen what to push to "Change Boot Options" or for "Boot Options") while it's starting up. If you press the right button, at the right time (when it's listed at the bottom, if it ever is), you should get the option to boot in safe mode, boot this, boot that, and "boot from network."
Like I said, I'm not too sure, so don't quote me yet. It won't be too hard to try, though, even if it is to no avail. Hope I'm helping.
