Thanks for support mciahel!
One strange thing is happening actually is that i’ve installed nero7 too and i tried to burn the same image which failed both with alchool and img burn and the the simulation gone smoothly even in RAID mode
Asking to ASUS support (the vendor of my mother board) they told me that they don’t know such types of problems with the last chipsets.
So, can you figure out why img burn and alchool failed but not nero? It sounds a bit strange
