My father first introduced me to Linux (an installation disc he borrowed from his employer). It didn't work. It just didn't click for me, and I didn't know why my Dad would consist that I use it.

Fast forward a few years a couple of friends around my age introduced me to Linux; it was Ubuntu back when it was hipster and trendy and friendly. I started by dual booting (probably WUBI) and then switched completely.

This is just purely anecdotal, but my conclusion is that it just didn't work when a parent forces a child to do anything. Better to influence the social circle of the child so that the child can be convinced to learn use Linux from friends.
