Create an automatic installer with clonezilla from a buildroot image

I’m seeking for advice/help about clonezilla. I have a costume made buildroot image, and I would like to create an automatic installer with clonezilla, so I don’t have to dd the image directly to the hard drive on other machines, just live boot and install it automatically.

I tried clonezilla on a machine where the image was installed but the only thing what I was able to achieve to read back the partitions to a portable media.

Any help would be appreciated
