He went in his sister room.
"Don't go inside. She doesn't like you go in her room."
"Don't go inside. She doesn't like you to go in her room."
Go or to go?Which one is the correct?
The correct one is:
"Don't go inside. She doesn't like you to go in her room."
You can only have one active verb in a sentence (or clause). Here that verb is like, as the primary verb with the auxiliary do. Whatever follows is the object of her dislike.
She doesn't like < something >.
Then, go is a secondary verb and can be in the infinitive form to go or the gerund form going.
So the construction can be either:
She doesn't like you to go in her room. (Infinitive)
or
She doesn't like you going in her room. (Gerund)
It cannot be
She doesn't like you go in her room."
because go is not the active verb here.
This is just the wrong word choice, in my opinion. When you use the verb like like that, a common word to use is when:
She doesn't like it when random people enter her room.
In your case, I would suggest that you switch to the verb want instead:
Don't go inside. She doesn't want you to enter her room.
But on the technical side of things, you do need to use a to in front of the second verb:
I would like you to be my friend.
