Try make with Rufus, same output on screen?
Regards,
I will try make the same with another program, and if it happens again, I will try make a different boot image for another software, like, example, Rescatux, and see if it happens again.
Maybe that Yumi doesn't do the things like Hirens wants
Not sure about this...
I remember to have some problems with some USB stick, using some particular distros, if it is a USB stick try change, if it is a real CD, maybe is damaged or corrupted data wrote on surface, experienced the same with OpenSuse, a damaged DVD was failing during the install, lucky OpenSuse saw that and aborted install.
