What? Backtrack 5 is only 1.9 gb iso! Were did u get this idea from? If your talking about adding it to Katana or hirens cd list then maybe its to large! I'm using Unetbootin and putting multiple .iso's to drive and all the tools for editing windows of course I will have to install the windows .exe this way ,but admin wants it to be clairvoyant. So he can see edited files and tools used. We always suspect any Tool Downloaded from internet to have a possible virus or trojen horse. So Admin leaves tools on His computer.
