We're almost ready to create an image. There are 3rd party utilities that might work, but an image will ensure you won't have to worry if it's gonna work. Here's a link that you'll never need with Ghost. Create an image before doing anything that might hose your system. I don't install any games to my boot partition.
Games are relatively easy to re-install, if needed.
But make sure everything works correctly before deleting the old image. I once deleted an image too soon. I have a partition dedicated solely to Ghost images. I never defrag this partition - regardless of what percent fragmentation shows up. I don't want any thing messing with my images.
