Ok .... basically the quick fix for me was to copy /usr/lib/syslinux/gfxboot.c32 onto the USB-disk to match the version of syslinux mbr actually installed on the USB-flash.
I guess a plausible fix would be to just copy over all syslinux files and not used those present in the iso-file from the beginning. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
