Maybe this wiki page can give a guideline for the ISO creation step: https://wiki.debian.org/RepackBootableISO especially with an older Live ISO: https://wiki.debian.org/RepackBootableISO#What_to_do_if_no_file_.2F.disk.2Fmkisofs_exists > Creating an image that can be booted from CD/DVD as well as from a USB > device is possible with xorriso, but not with genisoimage. If the old ISO does not have an MBR for booting from USB stick, then one may dare to use Debian's /usr/lib/ISOLINUX/isohdpfx.bin It might be that the ISOLINUX stuff of the old ISO does not work with the current MBR, though. Then it would be necessary to to replace the ISOLINUX bootloader "isolinux.bin" of the ISO by the neighbor of above MBR file /usr/lib/ISOLINUX/isolinux.bin Have a nice day :) Thomas
