Bootable CD's and ISOs

[Xsorovan]

Hey All!
Question for you all!
We have a bootable CD we use (BartPE) and we need to tweak some settings AFTER the ISO has been created. Does anyone know if anything special happens with a bootable CD ISO that would be messed up by extracting the ISO and then putting in the files we need and then burning the extracted files to CD?

I guess what I'm asking (a little more clearly) is if when a CD boots does it check a certain part of the CD or is it simply in the file structure?

My thanks in advance!

In order for the CD to be bootable you need to have a boot image on the CD. You can make a CD bootable using NERO. You could modify the contents and then create a bootable CD using NERO.

Most are for Windows XP, but if you skip the first steps about the actual ISO creation, and just go straight down to where it tells you the disc/program settings, you should be good to go.

If all you're doing is adding a file, and that file isn't related to the boot process, you should be able to extract the iso using winimage and add the file, then re-create it. It should still be bootable.

no he's talking about the nice PE bootCD from that guy bart (go google BartPE). it basically is a boot disc that takes some of ur windows file and boot into a PE (Preinstallation environment) with Windows GUI (asw opposed to DOS).

and to answer your question, you shouldn't mess with the iso file and extract and rebuild, there's a tool on BartPE where you can tweak your setting and rebuild the ISO (with the boot sector of course) if i remembered correctly, if not, you can always use ISOBuster (find it on google) and open the ISO file, extract the necessary files you want to edit and re-inject them back into the ISO, that way your boot sector is intact...
