Cloning systems with different HAL's or Hardware Abstraction Layers is and has always been a major problem.

The only way I have ever been successful at doing this is on machines with the EXACT same motherboard at the very least.

You then have to install the proper drivers for any new / different components.

The most notorious component that creates problems when cloning machines is the graphics adapter. If different from the master machine you are always best off by installing the generic vga driver prior to making the clone.

The next real problem is that simply cloning a windows install does not change the SID or system ID this will cause conflicts with machines on the same network or machines attempting to get updates from Microsoft.

There is a utility that is available to prep a new machine that has been created from the cloned image that generates a new SID upon initial boot.

Google for something called sysprep.

So things to take away to clone systems:

1) almost ALWAYS has to be the EXACT same HAL/mobo
2) careful with video cards / drivers
3) research and learn to use sysprep
4) make regular sacrifices to the microsoft gods
