So, same problem here. Live 13.10 USB key created with usb-creator-gtk, tried on a Dell Latitude E6400.
Yesterday, with an unformatted hard disk, it worked: live system came up without trouble. Today, with a harddisk formatted ext4 (whole disk; no partitions), doesn't work. Boot bails out with an initramfs busybox prompt. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1241589 Title: ubuntu 13.10 unable to boot on live usb (busy box - initramfs) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1241589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
