iATKOS | United Kingdom

Hi, I need help, I have a notebook that does not boot for usb for some strange reason, it only starts by DVD. So download the iatkos s3 v2 because it is the only one that enters a 4.7gb dvd and from there create the bootable usb with yosemite vanilla (the iatkos takes it as a macbook pro 4.1 and read that it was the last supported version) but not I can boot the usb from the chameleon. My question is if there is something that can burn on the dvd to boot the usb with yosemite vanilla

I have an intel t5500 and a nvidia go 7400, it's an old notebook, I know :)

Thank youuu
