How to install windows 2000 on top of Windows XP

[vias]

I have already installed windows XP on my system with some
other software.

Can anyone one suggest some solutions as to how I could install Windows 2000 on the same system as XP - without
the need to re-install XP again.

Thanks.

I have both xp and Windows 2000 Advanced server installed on the same machine. I have setup a dual boot, but I had Windows 2000 Prof and Windows 2000 Prof with a dual boot before I put XP on the machine. I update Windows 2000 Prof with XP and almost everything work OK.

I am going to try to replace Windows Advanced server with professional this week end. I am a developer and need various environments to test.

There are several device drivers that work on W2K Prof that do not work on W2K server.

I use Partition Magic by PowerQuest, I had to buy an update to work with XP, but it seems to work fine.
