How do to you gain weight if you don't like to eat?

If you don't eat, you're not going to gain weight. The only way to do it would be to eat regularily then eat nothing. Then fat will build up making you gain weight. This is a very unhealthy way to gain weight. It's simple, eat more than you usually do, you gain weight. Eat less, lose weight. Eat the same amount, weight stays the same. Advice for you would be eating three big meals, not much snacking. That way you will get more calories in.
