So ive been cleaning out my hard drive becasue its been too full and i noticed I had under the halo reach game “installed xbox 360 game” and it takes up 6.6 GB. and i rememeber downloading it because they said the load times would be shorter. But the space would be really valuable so i just want to make sure deleting that wont erase my saved games or anything in the armoey or anything like that. any help would be greatly appreciated!!
It wont, thats in a different saved file. Just put the CD into the drive, hit Y on the game as you would to install it, but press delete game off hdd
So just to be sure. I am totally safe with deleting/ uninstalling it??
Yes you are safe. You are simply removing the installed file, not the game it self. 
ok thank you!! im not very knowledgable in this area as you can tell. just wanted be safe and not sorry
THANKS AGAIN!!
You are most certainly welcome. AT EZ.
