    Default [mkisofs] how to make an image bootable

    Greetings !!

    I have an image with a autorun.inf file on it and wanted to make it bootable on a simple cd (700Mb). Untill now I tried and failed to make it bootable. The image is on the cd but the cd won't boot.

    I tried also under windows (with nr0) and failed again... no way to boot on this cd with the image I created.

    I need more informations or how toes ^^ to use the "El-Torito" features for the mkisofs utility that I use to create my .iso files.

    Thank you if you could wipe out my ignorance ^^

    You need to create the iso image adding an "El torito" boot image (option -b for mkisofs, and
    others), which you have to create separately. See "man mkisofs".

    Notice that the autorun.inf file is not related to this at all.

    Thank you !
    There is no more steps to do but add the -b option ?

    -hard-disk-boot
    -no-emul-boot

    Which one of these options should be used in case of we don't want to emulate a floppy disk boot ?
    I will try and then send feedback of what happened, fortunately I can test with virtual machines if this work or not ^^

    I don't remember, it's long since I created one (and it was for msdos).
    The idea is that the boot image is separate from the dvd/cd image. Kind
    of a hack. You will have to investigate, surely there will be howtos
    around, googling a bit.

    Yes, that will be handy. Post whatever you find, please :-)
