I'm trying to follow the steps here to slip a Kickstart script into an ISO image. Despite following exactly, I'm hitting the error below. I've tried this on Debian as well as a CentOS system with the same result. As far as I can determine, the Eltorito boot image `EFIBOOT.IMG` Is not present or copied with the previous commands.
Anyone have any ideas why this might be the case?
