How to restore a disk as a image, not careing about any partitions

[Pat]

Hi there,
when using clonezilla live, mode "device-image" and by choosing "savedisk" / "restoredisk", I'm wondering that it cares about partitions (e.g. creating partition tables, restoring each partition individually). I would expect that it just dumps/restore the whole disk on block level (assuming backup/restore happens on the same disk / disk geometry).

Additionally, I wonder why it tries to invoke grub-install (due to -g auto argument of ocs-sr)).
A true disk image should also contain MBR / boot loader / partition tables.

Am I missing something?
Is there such a "real image" functionality in Clonezilla Live?

Thank you.

"I would expect that it just dumps/restore the whole disk on block level (assuming backup/restore happens on the same disk / disk geometry)." -> Clonezilla will scan all the parttions in the disk then save/restore them.
"it tries to invoke grub-install (due to -g auto argument of ocs-sr))." -> This is due to that the boot loader should be restored when the disk is diffrent.
"Is there such a "real image" functionality in Clonezilla Live?" -> Well, this is way what Clonezilla is. If you really want to sector-by-sector imaging, no matter it's used or not, "dd" is what you need.
