By any chance, had the option of setting up an overlay partition been chosen while installing KNOPPIX using the flash-knoppix script? If it isn't the case, the script can install the KNOPPIX on a FAT32 partition without re-partitioning and re-formatting the entire USB flash drive. If the partition on which the KNOPPIX is going to be installed isn't the first partition of the device and isn't in the vfat format, the script just quits without touching anything.

It's way too technical for my level to understand exactly which part of the ldlinux.sys file (stage2-part1 and/or stage2-part2 as mentioned on Arch's wiki regarding syslinux) has been altered during the resizing process. Re-installing syslinux shall bring the flash drive back to bootable.

Just out of curiosity, does the NTFS partition need to been seen in the Winodws Explorer?
