You are lucky because this place has some of the friendliest helpfull people I have ever come across. Between RMS2001 and Quall999 they have never that I have seen not helped someone or made them feel as if your asking a stupid question.
I just finished modding my XBox and have never before soldered or used any programs like ftp. Today I feel as though I am a pro
As far as I would say that is a disclaimer just warning you of the a risk you take. I have not known anyone who has messed up there hdd beacuse of evox. Not putting it in your hard drive would drive me nuts having to boot it up and its a pain as you must turn it on put in the disk let it load turn it off and turn it back on. Its much easier to just turn on your XBox and it goes to evox and from there go back to the MSDASHBOARD
