hello every body, I'm trying to build an isohybrid image based on syslinux able to boot on bios and uefi with optical disk or usb key. I've build a 16Mb hard disk image (core.img) with necessary parts for bios (legacy bootable partition, protective mbr, gptmbr.bin & syslinux installation) and for uefi (gpt, esp, /efi/boot/bootx64.efi & syslinux files). my hard disk image is ok -

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

My interpretation of Didier's questions is less depth and more user-friendly practical commands for end-users. Our points of view

Hi, i'm possibly not the best source of general SYSLINUX knowledge, as my interest in it is only with my xorriso hat on. (As you can see in the SYSLINUX wiki, xorriso can do the isohybridization without the need for the isohybrid program.)

Hi there, I failed to boot an installer in a VMware player (Version6.0.3 build-1895310) using syslinux 6.03, be it off an hybrid ISO image and an USB stick. Booting succeeds if the VM is set to use a BIOS firmware with both media, but fails using an efi firmware. Trying to boot off the ISO image I get an error message "The firmware encountered an unexpected exception" Trying to

Precis: I?m trying to debug a problem with CentOS7 failing to install from an ISO written to a USB pendrive ? anyone got suggestions? What works ? installing on a modern, ?standard PC?; the pendrive image boots and installs as I expect What does not work ? same pendrive booting in an ATCA blade. What I?ve tried is? 1. Boot the standard CentOS7 minimal image. This seems to start but then

Well, besides the fact that after loading the kernel and the initram it didn't started the boot process (don't know why), this is what I achieved by using a disk image with syslinux.efi... :-) -- "Si quieres viajar alrededor
