I think the configuration of isolinux.cfg is wrong.. I tried every solution here on " ask! " but all failed for me..

I'm trying to install the ubuntu 14 with usb boot, i already got the iso file from ubuntu officil website, and the universal usb linux installer

enter image description here

    Try another USB creator, like UNetbootin, or a different version of Universal USB Installer.

    And check the md5sum of the iso. If this s a custom iso, post the isolinux.cfg

  • That's not just an "unknown keyword", it looks like binary jibberish; something's gone wrong. +1 to re-create the USB, maybe with a different tool, & check md5 of iso

Instead of trying to fix an error which should not exist, better to check the Ubuntu Official hashes and to download the .iso file again.

This will be much easier and more robust then trying to fix it yourself and then finding something else somewhere else went wrong as well. ;-)
