Ed, Larry
Many thanks for your comprehensive replies.

Enough to put me off even bothering to attempt a dual boot system. Especially as it isn't that critical. I need the NT4 in order to be able to install a new scripting system which I'm being trained in for develpment of a new project. They won't support it under Win2K because it hasn't been fully tested under that OS, hence that option was scratched out.

Think I'll just dedicate a small hard disk to the NT4 and physically plug it in or out as required.

Regards

Harry
