Interesting result. How did you make the MBR of the overall device which then hops onto the code at the start of the partition ? > I wonder if there is a good reason this doesn't come as a default option? I do not see (yet) how one could combine UEFI with a partition MBR in the same image. It seems to me that one would have to extract the EFI System Partition from the ISO and put it onto USB stick as separate partition of type 0xef. One would simply leave out GPT and rely on the middle legacy boot path of UEFI. (Younger than BIOS emulation but not as shiny as GPT.) If a partition MBR is desired, one would need to use a different MBR template file. According to http://www.syslinux.org/wiki/index.php?title=Isohybrid#MBR_selection this would be isohdppx.bin. (I wrote that table from existing SYSLINUX docs and am not aware that anybody ever tried whether it is correct. Your mileage may vary.) Have a nice day :) Thomas
