Why doesn't the disc 2 content install for Fallout 3 Goty edition?

So this trouble shooting, does the Xbox 360 fallout 3 goty edition dlc disc installed content get uploaded to the cloud and downloaded to the Xbox one hard drive?

Yea I get the code part, but say for example Fallout 3 and New Vegas GOTY editions come with 2 discs, one for the game itself, and the other has all the dlc on it. I'm asking if I install the content from the second disc that has the dlc on it, will it be attached to my account.

Hello,

Have you formatted your hard drive, if you haven't please take a look at this post by Seagate.

The message you get is because you need the official Xbox 360 hard drive installed. Not an external USB drive.

If you have Fallout 3, whether it be from a disc or if you purchased it from games on demand, disc 2 from the GOTY edition with all the addons or the Broken Steel/Point Lookout disc will install onto your xbox 360 hard drive and be playable upon starting
the game.
