installing extlinux on a fresh system. Why does it fail ?
Thanks I let GParted create the file system. It was done on a rescue disk of Ubuntu 12.04 (GParted 0.11.0) I think that the problem is in my command line.

Determine from which device syslinux booted from
The RAW nature of Disk Imager fails to leverage the unique intentions of UUID to surmount the problems of multiple bootable drives in the same system for purposes of knowing which one you actually booted from and should continue to use.

Determine from which device syslinux booted from
Then again, I suppose you could have a script in your init that detects when it has been booted from a *special* UUID. In such cases it goes to the first instance of a volume with that *special* UUID and re-writes it to a genuine UUID, as well as updates the syslinux configs on the volume. You could then create your seed image with that *special* UUID and then even an XP user could write it to a

isohybrid --uefi - resulting EF00 partition too small
Hello everyone, I am maintaining a distribution loosely based on LFS and am now trying to add UEFI support. Integrating a FAT formatted partition image containing, preloader, gummiboot, kernel and initramfs correctly results in a ISO image that is bootable on BIOS and UEFI systems if booted from the optical drive. However, when I run isohybrid --uefi name-of.iso the resulting GPT entry for

Loading syslinux.efi from preloader.efi
Hello everyone, I am trying to prepare a UEFI bootable thumb drive using syslinux and Linux foundations PreLoader.efi. I started the same as as it works with gummiboot-42: * Copy PRELOADER.EFI to EFI/BOOT/BOOTX64.EFI * Copy HASHTOOL.EFI to EFI/BOOT/BOOTX64.EFI * Copy gummibootx64.efi to EFI/BOOT/LOADER.EFI With just those files PreLoader asks to enroll gummiboot's hash. I do so and

Syslinux 5.10pre1 - Failed to load COM32 file .c32

But I already fail when booting from CD with Failed to load COM32 file .c32 I am a bit perplex since no name of COM32 files is given. I am trying to trace down the issue as good as I can.

I have not looked into it all that much. But seems that UEFI basically allows booting without a bootloader. Here is some gentoo wiki info in it: http://wiki.gentoo.org/wiki/EFI_stub_kernel And Greg Kroah-Hartman talking about it a bit: http://kroah.com/log/blog/2013/09/02/booting-a-self-signed-linux-kernel/ I am looking forward to making a little HOWTO, for this subject and also for using

installing extlinux on a fresh system. Why does it fail ?
Hi All, I am trying to install extlinux on a fresh system. Here are my steps : ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ A) Create an ext2 partition. I did the following steps : 1) boot from CD 2) Activate GParted 3) Create Partition table on the "fresh disk" (/dev/sda). 4) Create 1 ext2 partition (and mark its flag as "boot"). B)mkdir /mnt/Ext2_partition C) mount /dev/sda1

In fact I usually use preloader.efi (with keytool.efi and hashtool.efi for secure boot) and gummiboot.x64.efi to boot EFI stub kernels on x86_64. But until short time a go I had no idea someone would try to sell 32 bit UEFI on
