So I borrowed the game from a friend who let me play it this weekend to see if I liked it or not before actually buying it, and needless to say I loved it, got through the first four chapters.

But today I of course had to return the game to him, and now I want to purchase it myself, but where does that leave me in terms of the first four chapters I completed?

If I buy the game and play it on the same Xbox One that I played my friend's game on, will I still have my saved data? I really don't want to have to beat the first four chapters over again as it took me almost three hours.

On Xbox 360 I know that the saved data had nothing to do with the actual disc, but everything to do with your specific hard-drive data. Is this still the same on the Xbox One?

Basically, will I still have my saved data even if I switch discs?
