I have been thinking about how i could play Xbox360 games without switching discs. Yes of course there is always games on demand, but usually by the time they get the game on there i already bought it. What my idea is with the ability to install games to the harddrive, the full game is installed except it wont run without the game id. So I was thinking, what if someway i could make a iso that would just contain the game id's for my games. So i would just be able to run all my games off my harddrive with one disc. It would take some time to gather all my game id's, but that is not the only problem with my theory. There is also the issue of the xbox not actually reading the disc. Now if someone can help me find a way to get the official xbox360 iso signature on a blank disc, I would be set. But I can not think of a way to do that. So please if you have any ideas on how I could create a disc that would run on a unmodded xbox360 please message me so I can progress on my project.

You would have to emulate that partition of the hard drive to be a disc, which would be next to impossible.
