Xbox Live e Xbox Game Pass Ultimate juntos

Hey there! if you upgrade, it will auto convert your existing Gold. So you'll have 12+ months of Game Pass Ultimate.

If you subscribe to Game Pass Ultimate, your remaining Xbox Live converts into Game Pass Ultimate days. If the Game Pass Ultimate has run out you can either carry on with Game Pass Ultimate, or buy Xbox Live on its own. If you cancel Game Pass Ultimate
you lose any pre paid Xbox Live time.

Seems like it's not asking you for a Game Pass but it's asking you to subscribe to an Xbox Live Gold subscription, the reason why Xbox Game Pass Ultimate is one of the options is due to the Xbox Live Gold included on the Xbox Game Pass Ultimate.

You will be needing to subscribe to either Xbox Live Gold or Xbox Game Pass Ultimate to play the game, Ghosty2506.

Hi,

Once you upgraded to Xbox game pass ultimate, your Xbox live gold will be carried over to Xbox game pass ultimate. For example, if you have Xbox live gold for a year and you upgraded it to Xbox game pass ultimate, your Xbox live gold and xbox game pass for
console and PC will also be good for 13 months (12 months Xbox live gold+1 month upgrade Xbox game pass Ultimate). If you cancelled the Xbox game pass ultimate, automatically your Xbox live will also be cancelled since it is already merged to the Ultimate.
You need to contact Xbox Support to reinstate your lost membership.

Once you activated the Game Pass Ultimate your Xbox Live Gold was converted to Game Pass Ultimate time. If you cancelled Game Pass Ultimate, then you lose your Xbox Live Gold that was converted.
