similar to: Fail to boot ISOs using EFI

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.)

I posted this on the bugzilla page but I figured that on the mailing list it would get more attention. Please see http://bugzilla.syslinux.org/show_bug.cgi?id=49 for a description of my current issue. -- Thank you, Fernando Reyes GPG BDD75DD7 Mission Accomplish, Inc. http://missionaccomplish.com Email:design at missionaccomplish.com Tel: 7187100008 Cell: 3479275477

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

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 -

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

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

I have been using syslinux-6.x along with isohybrid --mac and --efi option to create a usb hybrid iso with EFI support. The thing with EFI is that you'll need to use grub as your bootloader for EFI but isohybrid does setup the proper partition schema for EFI. You'll need to use the following to generate an iso that works. xorriso -as mkisofs -J -R -l -V some-vol-label \ -o ../image.iso

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

Hi, i have implemented in xorriso the equivalents of isohybrid.c options --mac and --uefi. There remains the question how to ensure that the submitted MBR is prepared for the 32 byte mock-up of an APM Block0. I see in git of may 2012 that all mbr/isohdp[fp]x*.bin begin by 33 ed 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90

Hi All, I am trying to make a customer ISO. When I run this command: mkisofs -o $DESTINATION_FILE -b isolinux/isolinux.bin -c boot.cat \ -no-emul-boot -boot-info-table \ -V "$NAME" -boot-load-size 4 -boot-info-table -R -J -v -T \ -eltorito-alt-boot -e images/efiboot.img \ $DESTINATION_DIR it tells me: Size of boot image is 4 sectors -> No emulation

My criticism towards this UEFI implementation is that it probably cannot serve as realistic test bed for the first stage of UEFI booting. It seems far too

I did the dd of the ISO to a 16G USB device. the second partition is FAT so I can edit it - I want to make a custom menu entry. I edited the grub.cfg - but that did not work - my menu option does not show. Then I think I need to change BOOT.cfg and generate the grub.cfg - but I dont know in this case how to generate for the USB device. What command do I use for that ? Thanks, Jerry
