What is Pre BOOT Image

The Pre-boot Image field displays the pre-boot image version written to the drive’s shadow MBR. If the field displays “Not Supported”, then the drive does not support MBR shadowing, and the pre-boot image cannot be written to the drive. If the field displays “N/A”, and the selected drive is a TCG drive, then the pre-boot image has not been written to the drive. For the USB version, the pre-boot image is not available.
