Public bug reported: I am able to boot ubuntu 13.04 desktop from DOK using following grub2 config:
menuentry "Ubuntu 13.04 Desktop amd64 ISO" { loopback loop /boot/ubuntu-13.04-desktop-amd64.iso linux (loop)/casper/vmlinuz.efi boot=casper iso-scan/filename=/boot/ubuntu-13.04-desktop-amd64.iso noeject noprompt splash -- initrd (loop)/casper/initrd.lz } Ubuntu 13.04 server boots, but then fails to find CDROM image. If manually mount the iso at /cdrom, I am able to skip the step and continue the installation. (it fails later for a different reason, so I am forced to use netinstall for now anyway) menuentry "Ubuntu 13.04 Server amd64 ISO" { loopback loop /boot/ubuntu-13.04-server-amd64.iso linux (loop)/install/vmlinuz boot=casper iso-scan/filename=/boot/ubuntu-13.04-server-amd64.iso noeject noprompt splash -- initrd (loop)/install/initrd.gz } Here is a working stanza for netinstall: menuentry "Ubuntu 13.04 Server amd64 netboot" { loopback loop /boot/ubuntu-13.04-server-amd64.iso linux (loop)/install/netboot/ubuntu-installer/amd64/linux initrd (loop)/install/netboot/ubuntu-installer/amd64/initrd.gz } ** Affects: debian-installer (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169950 Title: Installation from flash for ubuntu server 13.04 fails to mount CD/ISO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1169950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
