Yep that simple.
If all is fresh I install on first partition, activate it,set up all my gaming perifials. Then ghost it, then use ghost to install the same OS on the next partions.
That way Bill thinks I only have one install.
Then once that is done I add all my normal PC stuff to the first partion, and then Ghost it.
Now I have a ghost for both partions, and in a pinch I can fly on both.
I used to be in an International compition, and my PC died 15 minutes before a match.
I vowed never again will I not compete, due to O/S problems.
Hardware may get me some day, but no longer will software.
Unless the game itself dies.
Now I also have a third and forth partition/drive.
One is My Documents, and I have both O/S directing to it, via the My Document icons.
Next partion is all my Games. Most like IL2 do not require a registry key. So it works quite well. Even if bot O/S die, I still have al my games and settings.
Short games like Lockon that require registry keys. I then have to ghost the drive,or reload O/S and install Lockon again. in default location. Once its installed. I delete the stock location folders, and my origional in the seperate drive works again as if nothing ever happend.
