Hi,
I had created a live usb of Kali because my laptop can't reed the dvd boot (I tryed lot of times but I don't know why it doesn't work), when i start it from reFIt, come out this:

so if i clic on DEFAULT i have this

The only thing I can do to run in Kali is to press TAB in the first page and add "nomodeset noapic nolapic" in Live mode, and I can enter in the SO.

I had try to install in a partition from "Install with speech synthesis" and everything is done but when I start Kali from rEFIt I have a black monitor and reed the sentence "This is not a bootable disk".

Someone can help me please??
