similar to: Getting classic BIOS and UEFI boot on the same disk?

I just created something very similar for one of my own projects. I have a disk image that you can "dd" onto a hard drive or USB drive and a bash script demonstrating how it was done here: https://www.syslinux.org/archives/2019-July/026476.html You don't actually need the patch for the dual BIOS/UEFI support. The patch in the above link is just to enable the reading of config

Hello Greg, thanks a lot - I will try out your script next week. I jut went through the script - there is a line containing: bls1 include I would carefully assume that this line is only valid when patching syslinux, correct? What will happen if this is read by a non-patched syslinux? Will it cause errors or will it simply be ignored? Best regards, Erik Gregory Bartholomew wrote: > I just

I'm not sure if it is useful, but with the advent of UEFI only machines, we've run into a similar problem w/ out custom CentOS 7 USB installation keys. Basically, we create a gpt device w/ a single FAT16 partition (this would be your /boot partition for a full installation) containing an EFI/BOOT/ directory with the syslinux-efi files and a SYSLINUX/ directory with the syslinux-bios

Hello all, We're having the following issue: when in UEFI mode, any output/errors from a lua script is invisible! This occurs even just running 'lua -v'. It runs and returns to a (visible) 'boot:' prompt, but there is simply no output visible from lua! (It does do a linefeed, but no visible text appears.) Has anyone encountered this? And/or know of a solution? For

Hi Apologies for referring back to an old thread, but in this conversation https://www.syslinux.org/archives/2018-October/026198.html Thomas and Ady seemed to suggest that booting 32-bit linux from 64-bit EFI was possible with the patched 6.04-pre version of syslinux that Debian are using. When I try this, all I get is Loading ../../bzImage...ok Loading ../../imgpt4.gz...ok and then nothing.

Dear gentlemen, I think I'd better start another thread for this... thanks to Ady Ady and Gregory Lee Bartholomew for their responses to my early question. Just for the record, my fresh experience with PXElinux 6.x follows: syslinux.efi version 6.03 does boot to the extent that it shows a prompt, but if I provide it with a CFG file containing several labels, no matter what label I type

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 posted this on the bugzilla page but I figured that on the mailing list it would get more attention.

At least the ISO will then have MBR, GPT and APM entries for the file macboot.img. I did that, and also tried the xorriso command you posted.

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.

Do note that not everyone is running a Debian based system, so "the current Debian Testing binary packages" are worthless to us.

So last week I was wondering if XFS was still working -- even with its last on-disk structure changes -- and it _suprisingly_ worked as expected. Right, now I can finally get rid of GRUB and use Syslinux to boot my Linux on EFI from a rootfs with xfs. Shit, I have two partitions (the first one being the required ESP) so there is no way to access the other partitions since because Syslinux does not

-- Re-sent as original may be stuck at awaiting "authorisation" (originally sent before I joined the mailing list) Hi All, It is impossible to boot Linux-based ISOs that use Syslinux 6.02 via CD or DVD on older - non-UEFI - systems.
