What program are you using to create a System Image (Windows 7 Backup utility or some other program)?
Are you sure you have enough free space?
Can you post a screen shot of Disk Management? Disk Management - Post a Screen Capture Image
I don't use Windows 7 Backup as it includes all partitions it sees as "system" partitions...
With a multi-boot PC the Images are too large (for me).
Other programs such as Macrium or Acronis offer much more control and I can specify what partitions to include in the Image.
You could try Macrium Reflect (free), if you haven't already. Imaging with free Macrium
It looks like you now have 3 threads for the same issue.
It's best if you stay with 1 thread to avoid confusion with different people helping in different threads...
Two of your threads have "Seagate 2tb possible partitions" in the title...
What does that mean...do you have a Seagate HD > than 2 TB, ... ???
