I am ready to capture an image of my Windows 7 professional computer. This was a computer that I did the upgrade to Win7 on. When I get into the Linux screen, I can see partitions 1-4 but when I do img pdall I see the following at the top of the screen.

Device /dev/sda then it lists the cylinders, heads, capacity, etc.

When I tried to capture and image it said "You must include at least 1 non-EMPTY partition."

So it seems to me that it's not recognizing that partition 1 is where the data is. In other words, how do I set it to partition one.
