By pass try/intall screen on boot

Hi world !

I've followed this but is not working, this one is not whatt I'm looking for , and either this is not working.

Maybe I'm doing something wrong, I've copied txt.cfg live content to syslinux, after erasing it.

I'm using Ubuntu 15.10 and uni-usb-installer for windows. I would like to not create a new bootable disk, I've already customized this one and the time was considerably.

Thank you every one!

Have a nice day!
