Can I keep both Game save files?

Hi LisaPizza, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

You can only keep one save file under one Xbox profile.

Once you go online your local save file with sync to the cloud.

Which local save file will get saved on the cloud. There are 2 on different consoles

Ye thanks but I want to know if I can select the option to install it to my console from the disc and continue my game there. Would that work? If it does will I still be able to play on a disc aswell?

Hi! First off: Save games are never stored on the game (disc or hard drive) itself ever. This is pretty much only the case with systems that use cartridges (like Nintendo 64, handhelds). I assume you are playing the game on your Xbox 360? If so it's depending
what you choose as your save location. Besides your local Xbox 360 hard drive/memory unit you also have the option to save your progress in the Xbox cloud, which is most likely the option you are looking for. See this link for further information about this

Hi there,

save games are by default saved on the console on the Xbox 360 (or cloud when that is selected) so the save isn't located on the disc.

If you used your own account then that save is linked to your account and present on your console (I assume you played it on your console)

If so then you can give the disc back and after you purchased the game (on disc or digitally) you can continue with your save game and your friend can play his save game on their console (assuming they played it on their console)

So in short, if you both used your own consoles and accounts then you both will be able to continue the game where you left off via your account their save games.
