Maybe it is a case of "if you have to ask, you don't need it"
I think that's the case... I believe most of us we are ok with providing help to people who have a specific problem, I don't think the aim of this forum or the UBCD would be to be a guide for anyone to solve their computer problems themselves.
( Techs have to earn their lives too, you know
Of course it's not a problem if one wishes to get some technical knowledge and try to solve his problems by himself, but UBCD contains powerful and potentially "dangerous" if misused tools, it's better not to use it if you don't already have a certain level of knowledge on what a certain type of tool is made for and what can be done with it, if it can be undone ... etc ^^
And you don't get such knowledge by just following a guide, unless it's very documented.
In addition it would be impossible to cover all of the problems that may occur with a personnal computer and give a 100% certain solution to each of them that anyone could follow.
