I have a similar issue trying to build a stock image using Raring. The binary/isolinux/txt.cfg file contains the boot menu options with the names initrd.lz and vmlinuz like this:
default live label live menu label ^Try Ubuntu without installing kernel /casper/vmlinuz append file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash -- Nevertheless the names of the files inside the casper/ directory are: initrd.img-3.8.0-25-generic and vmlinuz-3.8.0-25-generic respectively. So the bootloader can't find the files during boot time and shows the dialog message '/casper/vmlinuz' file not found, after pressing OK, it just stays in the splash menu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/965855 Title: Failure when attempting to boot from stock configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/live-build/+bug/965855/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
