Once again, I suggest looking at the Windows utility ISObuster to extract files from an img file.

For details on dd, type man dd into a Linux shell prompt. Or Google dd. I don't think that you're going to want to just copy the image to a new drive (or new drive partition) however. I certainly would not do it that way, I would format up the new drive properly and extract the files that I wanted from the image. It isn't clear what is on that img, isn't it a copy of the entire drive, not just the files that you need?
