[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 n€r0) 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 :slight_smile:
