@PHLin It could be related to this known bug: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1325801
According to 14.10 release notes (https://wiki.ubuntu.com/UtopicUnicorn/ReleaseNotes#Boot .2C_installation_and_post-install): Due to changes in syslinux, it is not currently possible to use usb- creator from 14.04 and earlier releases to write USB images for 14.10; we believe that it is also not possible to use usb-creator from a 14.10 system to write USB images for earlier releases. For now the workaround is to use a matching release of Ubuntu to write the images, but we intend to issue updates soon to work around this incompatibility. ** Changed in: linux (Ubuntu) Assignee: Alex Hung (alexhung) => (unassigned) ** Changed in: hwe-next Assignee: Alex Hung (alexhung) => (unassigned) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1391439 Title: [Dell Inspiron 5545] can not boot up by Ubuntu 14.04.1 USB-key.
