Thanks for the link Steve.  The linked document only pertains to boot.iso (netinst.iso).  The livecd-tools maintainer, indicated that livecd-iso-to-disk is not supported for writing DVD media to a USB key for install.  We'll need to chase that down outside of this specific bug.

Fore Fedora 13 the docs still point out to using livecd-tools to write boot.iso to USB stick:


While for RHEL 6 (docs still in development) is says:

      Become root:

      su -

      Install the SYSLINUX bootloader on the USB storage device:

      syslinux /dev/sdX1

      where sdX is the device name.
      Create mount points for boot.iso and the USB storage device:

      mkdir /mnt/isoboot /mnt/diskboot

      Mount boot.iso:

      mount boot.iso /mnt/isoboot -o loop

      Mount the USB storage device:

      mount /dev/sdX1 /mnt/diskboot

      Copy the ISOLINUX files from the boot.iso to the USB storage device:

      cp /mnt/isoboot/isolinux/* /mnt/diskboot

      Use the isolinux.cfg file from boot.iso as the syslinux.cfg file for the USB device:

      grep -v local /mnt/isoboot/isolinux/isolinux.cfg > /mnt/diskboot/syslinux.cfg

      Unmount boot.iso:

      umount /mnt/isoboot

      Unmount the USB storage device:

      umount /mnt/diskboot

Not sure which one is correct but docs need to be updated.

Hi Alexander,

The procedure provided didn't end up in the RHEL 6 guide in that form, and the Fedora 16 guide will feature a variety of options to write boot.iso to USB:  livecd-tools, dd, and LiveUSBCreator, plus the procedure for UEFI-based systems.

The draft of this section is at http://docs.fedoraproject.org/en-US/Fedora_Draft_Documentation/0.1/html-single/Installation_Guide/index.html#Making_USB_Media (the UEFI-based system option is earlier, in section 3.3.1)

If a problem still remains with these procedures though, please let me know.

Removing myself for these bug components as I'm either no longer involved in that aspect of the project, or no longer care to watch this particular bug. Sorry if you are caught in a maelstrom of bug changes as a result!
