Wont install (sorry for repost)

hi i dont know what to do. i installed halo 5 a while ago so i could download some other games. i wanted to re install it now but i cant. it starts the installation but then quits it about 10gb in. i try update later and update now but it doesnt work. i have enough storage on internal and external and i do have good wi-fi. it is not the disc reader as i have installed new games such as cod ww2 and it works fine. i dont know if the game wont install as it is a big game. i have tried restarting and shutting down my xbox but it wont work afterwards. anyone have any ideas?
i have enough storage on external and probably have enough on internal but i can move things if i dont have enough. reposted so i can get some help. thank u and let me know if there is a way to fix this

Halo 5 is currently 106 GB in size. That being said, it has be to installed on either your internal hard drive or external hard drive as I heard you’ll have problems playing it.

If youre installing from a disc try disconnecting from your network until the disc is fully installed. Once that completes reconnect and download the update. Sometimes installing the disc and update at the same time causes issues.
