...efi of program isohybrid is to be used with a GRUB2 equipped FAT filesystem image that is already in the ISO as its second El Torito boot image. Matthew Garrett developed this ISOLINUX+GRUB2 layout for Fedora. Many other distros follow his example. The next popular alternative is the layout of grub-mkrescue which boots both, BIOS and UEFI, by GRUB2 software. And then there is SuSE which grafts a second ISO superblock and directory tree onto an ISO which contains a GRUB2 boot image for EFI. (Less popular only if we count SuSE as 1 user, not by its many human users.) I proposed to mention this peculia...

Hi, if I inspect an hybrid ISO with tools like fdisk and gdisk, then looks like hybrid ISO has both the MBR and GPT in order to support both the BIOS and UEFI: # gdisk -l /dev/sdb GPT fdisk (gdisk) version 0.8.10 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: present Found valid MBR and GPT. Which do you want to use? 1 - MBR 2 - GPT 3 - Create blank GPT

I've been the maintainer of the G4L project since 2004, and have had great success using syslinux, but yesterday I ran into a machine that would not boot from the CD. The system system was a Lenovo L540 notebook, and it seems to use EFI? Disabled the Secure EFI, but it still would not boot. Comes up with the syslinux menu and seems to load the kernel, but then it just stops. Never shows

...the ISO. > Warning! Main partition table overlaps the first partition by 64 blocks! This is a consequence of the mjg multi-hybrid layout, which prescribes nested partitions. There is a school of thought which emphasizes that partitions should not be nested (see the results of GRUB2's grub-mkrescue with EFI support). ------------------------------------------------------------ If you really rely on Apple Partition Map and macboot.img, then test this with all machines in reach. If there arise problems, then send me the first 64 kB of your image for inspection, or upload it as a whole and tel...

The third boot image is HFS+, not FAT. I understand this is for pre-EFI Macs. Try a Debian amd64 ISO, e.g.:

I would be willing to try such an ISO with qemu+OVMF. Regrettably my real test iron has no EFI firmware. Do you know the

HI, In http://slint.fr/misc/MacBoot/ you'll find all context information. All files referenced here are stored there. Long story short: once dd-ed on an USB stick the ISO image can boot on a BIOS or EFI machine, but I want it to be able to boot on most x86_64 Macs with an EFI firmware. Unfortunately I get the error message: isohybrid: slint64-14.1.iso: unable to find mac efi image The

It is rather that no way is known how to let SYSLINUX understand the ISO 9660 filesystem outside of its ESP.
