I'm affected with Ubuntu-Gnome 13.04 Live-USB created with usb-creator from a Ubuntu 12.04 machine. In my case it has no relation with bug 492301 because I've also tried to boot with a multiboot USB stick (grub2 to select an ISO file in the stick; no usb-creator intervention) and the init message is the same: /init: line 7: can't open /dev/sr0: No medium found Can it be related with UEFI installed on the hard disk? (my today's testing case is a notebook with Windows 7 preinstalled; BIOS hasn't any option to disable UEFI) Ubuntu 13.04 Live-USB: error Ubuntu 13.04 ISO in a grub-USB: error Ubuntu 13.04 Live-DVD: boots (only acpi=off needed) * Ubuntu 13.04 Live-USB boots if there is also the Live-DVD inserted in the optical drive (after kernel loading Live-USB jumps to get all the data from DVD; sr0). - I've tried with Nguyen's workaround (altering casper parameters) with no success. - Once the hard disk is formatted, problem remains. - This is the second machine I've found in a month with the same problem (preinstalled Windows 7/8 that prevents Live-USB to boot). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/500822 Title: /init: line 7: can't open /dev/sr0: No medium found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/500822/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
