K-Flash is an image flashing tool. One will insert a thumb drive, and use the K-FLash utility to flash an OS installation media to the thumb drive. This could also work with a DVD writer if an external one is connected. Since all computers will come with a thumb drive with Kal-OS installed on it as a recovery tool, this is not necessary to make another Kal-OS image. This could however make Linux installations, or Windows installations.
When flashing to a drive, all information on that drive will be erased during a formatting process. K-Flash will only flash to removable drives such as a DVD, or thumb drive. K-Flash will not flash to a drive that is integrated into the computer. However, for reliability, it would be recommended to flash to a USB thumb drive.
