I used this kind of approach some years ago with VMware workstaion installed on a Linux partition, starting WIndows vm directly from another partition containing Windows 2k,
where I used hardware profiles to select if I would start it as native or as vm
it was not officially supported but worked very well ;-)

But I think is not feasible in Linux with Kvm, at least right now

What you would try to get is a sort of "in place" P2V...
You could follow something like this outlined by Richard WM Jones:

where the dd process could be directly from within Linux from the win partition device to a local file on it
and then verify if you can start Windows guest.
probably it could help to start creating a new hardware profile from within native w2k, so that you start then from it the first time in virtual....

if you have proprietary startup things (such as ati control panel or other hw controlling gasgets..) you should disable them in virtual env, eventually starting before in safe mode...

Just a starting point...
