Swap motherboards with Windows 2000 Svr

I work for a technical training company. We have images of each classroom setup. Recently we upgraded all of our PC’s. We upgraded motherboards as well. Now when I bring down any image of a Windows 2000 Server or Windows 2000 Advanced Server that was originally installed on the old machines, onto the new machines…I get a blue screen: Inaccessible_boot_device error. I believe this is due to the new IDE controller and the HAL and all that…but how can I fix this to use all of these images? PLEASE help!
