The question is how the partition table of the ISO would get to the start of the USB stick and how to adjust it so that it tells the unforeseen location of the ISO and of the enclosed EFI System Partition number 2. If booting via EFI this should suffice. Booting via legacy BIOS would need the address of the isolinux.bin program to be updated in the MBR code and also inside isolinux.bin itself so that the first 4 KiB of the program can load its other 34 KiB from the USB stick. (The terms are "isohybrid MBR" and "Boot Info Table".It could be done.) > The iso acts normal, the FAT32 partition less so. What does /sbin/fdisk -l say about the partition table on your stick ? Have a nice day :) Thomas
