I hadn’t touched my Xbox 360 in quite some time since getting busy with Xbox One and the Master Chief Collection. Today I fired the old box up and wanted to begin replaying Halo Reach, but I haven’t been able to find any way of starting the game over…fresh and from the beginning. I even went as far as to delete Reach and then download it all over again, but still it doesn’t give me a way of doing so. It allows me to continue the game from the last point reached. Can anyone tell me how to start Reach over again? Any help is greatly appreaciated!
Not sure if it’s possible to restart a profile. You could start a new xbox live profile.
^ As above, sorry OP but the only way to start completely fresh would be to run with a new Xbox profile
My friend had the same problem,in the end up he just made a new Xbox profile

I think that you can errase the save file at storage options, i cant use my 360 currently so i cant give an exact route
