Hello, ive downloaded iDeneb 1.4 OSX ISO file. I've burned it as image file into TDK DVD and when i try to start installation, it simply dont boot. I restart my pc, and then shows black screen with blinking pointer (like loading disk) and nothing. I tried to install same ISO on other DVD with 4x speed, but same. My pc has 4gb of ram, so i dont think, i should wait much time for it. Before that i was installing iAtkos, and disk booted very fast. What problem can it be?

PC:
Asus
4 Gb's of RAM
2.4 GHz
Intel Core 2 Quad
