I have a similar problem, see https://www.kubuntuforums.net/showthread.php?66770-Live-USB-does-not-boot&p=361703#post361703
I tried some more things, and the only thing I get to work is with the dd command: - Kali Linux - Ubuntu 14.04.1 iso image - Kubuntu 14.04.1 iso image What does not work: (dd nor usb creator nor Unetbootin) - Kubuntu 14.10 (I even borrowed a dvd RW from a neighbour and burned the image on the dvd) - Kubuntu 14.04 initial iso image - Kubuntu 15.04 daily - mint 17 As 14.04 is an LTS, IMO the problem should be corrected there as wel. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1325801 Title: failed to boot from USB disk with error: gfxboot.c32: not a COM32R Image boot: To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1325801/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
