Hi again, I'v downloaded WOMP in order to help you. You don't need anything from source package, you need just full working ISO (downloaded or created from source package). I hope you have followed the readme file for proper making of ISO. If you have followed my instructions, then only problem remains in filesystem extension you have used. Which app you use for building your ISO, cdimage or mkisofs ? Which options you use, if you use cdimage, please write also the explanation for the options used. Any isolinux/syslinux or linux CD needs Rationalized RockRidge extensions, also you need to enable Joliet extensions. I don't know if cdimage offer this to user, I use mkisofs (better to say, I use The_GUI v2.0.1). Read-only attributes also needs to be removed on isolinux.bin before building ISO. I hope you have some virtual machine to test your ISOs before you burn them. regards
