Recently I answered [this question][1] I explain a step-by-step "guide" for   grub install and grub boot error 

Since Ask Ubuntu doesn't have documentation like Stack Overflow's I was interested in making an answered question. Would this be helpful in the future? If yes, should I make the question as a Community Wiki or not?
