One could allow nested partitions and put whole-ISO partitions into the various tables. Debian "amd64" ISOs do it that way. They boot on BIOS via ISOLINUX and on EFI via GRUB2. MBR partition table: N Status Type Start Blocks MBR partition : 1 0x80 0x00 0 454656 MBR partition : 2 0x00 0xef 3440 896 MBR partition path : 2 /boot/grub/efi.img ... GPT partname local : 1 ISOHybrid ... GPT start and size : 1 0 454600 ... GPT partname local : 2 ISOHybrid1 ... GPT start and size : 2 3440 896 GPT partition path : 2 /boot/grub/efi.img MBR partition 1 and GPT partition 1 cover the whole ISO. Partitions 2 mark the ESP. But Vladimir is clearly opposed to nested or overlapping partitions. And all partition editors seem to join his opinion. Have a nice day :) Thomas _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
