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

Just to be clear on the topic, I decided to do some tests from scratch on my MacBook Pro. This are the steps and results: 1. I've pick my USB pendrive and zeroed it, and after that created a new MBR partition scheme with fdisk and a VFAT partition of 32MB. Later I dd'd the file /usr/lib/syslinux/mbr/mbr.bin from SysLinux 6.03 and set the boot flag on the partition, so it could be able to

I don't know whether syslinux.efi can be used for booting from ISO 9660 via UEFI. Currently there is no example around which would succeed without GRUB or GRUB2. When describing the UEFI

How to express the embarrassing fact that ISOLINUX is not ready for UEFI but isohybrid is ? http://www.syslinux.org/wiki/index.php/Isohybrid#UEFI would

Quoting http://www.syslinux.org/wiki/index.php/Isohybrid#UEFI: "The additional isohybrid feature for UEFI adds a partition to the MBR partition table pointing to the same file in the ISO 9660 filesystem as does the El Torito catalog entry for EFI." According to this (and can be see using fdisk) it's being created a partition-inside-partition just by setting its start and end

For testing purposses, I'm trying to hook on QEmu an ISO image that start automatically with syslinux (just a DEFAULT label and no TIMEOUT option) and change the kernel arguments to redirect the console to a serial port instead of the screen. So far I've seen that the SERIAL statement give me a welcome message and the loading of the kernel and initramfs on the serial port (but curiously,

The other half would be to write the MBR bootloader, that

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

If you are initially booting in (U)EFI mode (into rEFInd, or some EFI shell or any other EFI boot loader or EFI boot manager), then generally speaking you are expected to boot in EFI mode. But some (U)EFI firmware _might_ be able to

I set up a new project on my computer and created the development link. I am very new to Ruby and just need help in determining where to look to solve the issues I am having getting access to the project. Here are the errors I get when trying to visit my application: Bundler::GemNotFound: Could not find rake-0.9.2.2 in any of the sources

Hi all, Anyone have tried to install centos7 in kaby lake model or almost in previous model (2015 if I am not wrong). Experiences?? Is refind needed?? Thanks.
