Ubuntu CD image build software

Comment 9 for bug 1040557

I confirm that when I enabled UEFI and the beginning it displayed a black screen where I could choose between try Ubuntu, install ubuntu, test ram etc.
I selected the first option (I don't remember which was, try live cd ubuntu? ) and during the loading it crashed and bricked my laptop.

But when I replaced the laptop, with UEFI disabled, the live cd (usb) start automatically without the black screen.
