A Partition or even the Whole Disk Imaging feature would allow creation of a full image, and restoration from scratch, even if the system area gets corrupted. To make it fully powerful, if such image could be directly written to CD / DVD discs, or stored in a Network / USB Storage area, and the rescue disc be made capable of accessing this previously created image, to completely rewrite / overwrite the partition, the entire system can be easily recreated, even when the HDD gets completely damaged
