Fix syslinux boot error on Ubuntu USB
January 13, 2016

If you have made an Ubuntu based (Ubuntu, Lubuntu, Elementary, Kubuntu, Ubuntu GNOME, etc) USB using Startup Disk Creator, and it shows a syslinux error (example: Invalid keyword in configuration file), then here is how to fix it:

Type help into the boot: prompt, and press ENTER. Press ENTER.

The only disadvantage of this method is you will need to do this each time you boot to the USB.
