How can I re-install games?

Games being on a separate hard drive don't have anything to do with your ability to redownload them. If you bought the game and you are the one that "owns" it/has the license for it then it WILL be in your "Ready to Install" unless removed from the Xbox
completely due to legal reasons (that's a rare occurrence.) If the game doesn't appear there then one of two things may be true. It was a game from a game-share/home Xbox share and one of your friends owns it and they "took" their share back, or, its was a
GamePass/Games with Gold title. If the game you are looking for was a Games with Gold or GamePass title you will need to re-up the subscription to whichever service it may have been a part of in order to have access to them again. If it was off of a game-share
you'll need to reacquire that with the permission of whoever had it.

If you know for a fact you purchased the game and own it you should contact support.

Did you searching them in the Xbox store and reinstall it that way? Or you can log into your account online and view your order history and redownload the game from there. https://support.xbox.com/en-US/billing/xbox-subscriptions/check-xbox-live-bill

Hello Dominic,

Thanks for coming to the forums. If they are not showing in ready to install you can try searching the store for the games individually. Are these games purchased, free with gold? Also make sure you are on the account that owned the games.

Thanks,

Brad

Also, were these digital downloads or disc? May sound like an odd question but I have went to find a game I thought was digital download and it turned out I only owned it on disc. That was why I could not find mine in the "Ready to Download" section.

Digital.

I checked my order history, and oddly enough, the one game I was looking to re-install was not there. I'm looking for Black ops 4. Now, oddly enough, the black ops 4 DLC pass that I also purchased the same day is there, but not the game itself.
