Oh, thanks again. I will try eventually to finish this multiboot dvd. And about jetman's crystall ball, , I thought he updated the tutorial since then. And the last question that I need answered to finish this dvd: How I insert other iso's that are not in tutorial , in example Windows XP, Acronis True Image, WinPE, Arch linux, how I make a menu and when I select an option (category) to appear another menu and when I select the "program" to start and boot that kernel. At windows, it should work with ntdr, at linux it should be simple but how about the others like Acronis ? Thanks again very much and goodbye!
