I'm new to the forums so hey! I created my account on xbox.com instead of making it on the xbox i have just bought. Now I can't find out how to enter the information onto the xbox. I would absolutely appreciate if you'd help me. Thanks!
Turn on the console. Move to the sign-In square and press A. Move to Recover Gamertag and follow the instructions.
When creating accounts on a new console however, creating the gamertag there can give you a month of free Gold time, so you might want to create a new email address and create a new account to experience some online play for free.
