  • Fix bug: image files or substance files cannot be loaded during computer boot-up if these files are located on external (USB etc.) disks or Dynamic disks, or on partitions of which file systems are not same as boot file system.
        * It is not recommended to specify image files or substance files on above-mentioned disks/partitions, because these disks/partitions get ready a little later than normal ones at computer boot-up.
