All i want is to add a file on the LiveCD. I downloaded the Centos 5.3 LiveCD. I tried to use MagicISO, UltraISO and mkisofs to recreate a new iso with my files on the root of the CD. When i boot up the new iso created by MagicISO, UltraISO, or mkisofs I get "Cannot find root file system". Is there any steps for me just to add my files on the root of the CD. Any help will be appreciated.
