No option to choose saved file when joining friends game NMS

Navigate to where the game is stored. You can do this several ways, the easiest is to choose the 'My Games & Apps' tile, then navigate to the games section.

Once there, highlight the ESO tile, then press the menu button.

Select "Manage Game". This will bring up the option to uninstall.

When you select uninstall, it will bring up a screen that should have both your game and your game save data listed as separate files. Simply choose the game file. This will uninstall only the game. Your save data will remain unless you choose to uninstall
it.

Dont know why you would need a hard drive to play the game, unless you have saved the game to a HDD (which obviously you havent).

Dont know if this will work but maybe try saving your save game files to cloud and choose cloud when the option comes up when you launch the game.

Good luck anyway....

Hi AzKxRider520....yes I have the option to press X and go to an online lobby....but I can't join game of my friends on the Xbox's menu.....(people part, friends, choose a friend and go to "join party or game")....and my friends are in a public session.....

Yes. Just go to Options and choose to begin a new game. Then when you sleep in the bed to save..choose a different slot to save in.

I didn't write this,

"You need to both follow each other on Xbox One. Then in Zoo Tycoon, you can go to the Game Menu (press pause). Then select Zoo Friends List. You will need to save the zoo to the cloud. Do so. In your Zoo Friends List, click Add Friend and then Invite to
Party. Choose your partner. They should "Accept and Play" the invite. You will join a party and they should be added to your Zoo Friends List. Select their name and then choose Invite to Zoo. The "Come On Over to My Place" achievement should unlock right away
when you invite them. When they invite you following the same process and you choose to join and load into the game into their zoo, the "You in? I'm Coming Round" achievement will unlock."
