Hello, I want to re-install Mountain Lion on my Macbook Pro 9,2.

The thing is I don't have an internet connection where I live, so I decided to get a copy on a USB Flash Drive, It worked on another mac, the Macbook Unibody 2010, but this thing keeps connecting and asking for an apple ID, I don't want to buy a copy from App Store, honestly.

Is there a way to disable this ?
