I made an image (31GB) of my freshly installed Windows 7 on my C:/ partition a few months ago. Today my Windows is slow so I want to put my image. I suppose it's all about reading (the image) and writing it over whatever there is on my C:/, yet Ghost asks tons of disk space for the operation.
Why is that ? Why disk space is needed just for reading and writing ?
Edit: my image size is 31GB and is currently stored on a partition having 3GB free space, my C partition size is 80GB, my Ghost version is 15.0. To restore the image I clicked on "Run or Manage Backups", selected my image and click on "Run Now".
