Is there a live CD available which has this Software installed or do I have to create my custom live CD? I tested the JonDo live DVD but some applications are missing. If I have to create a custom one, which is the best OS for that? BartPE, Ubuntu, ...?
It depends upon which softwares you want, there is an live distro based on windows which includes lots of softwares, Its Hiren Boot CD, If you need more softwares, then you can create live cd as per your requirement, for linux, I will suggest for UCK(ubuntu customization kit) and for Windows BartPE is best, for bootloader, you can use isolinux.
