I don't want to continue with microslop and I want a very safe, fast operating system. This looks like it. However I have a few issues. I have like 3 different drives drive D and E have very important things to my family and me by extension. Does Zorin delete those files? Secondly I have games which I like a lot which I want to enquire if they run on Zorin. Such as Hearts of Iron IV, Crusader Kings 2 and Roblox (I'm 14 what do you expect). Finally I'm not very much into the coding aspect of stuff right so is this OS not as code and that stuff heavy as other Linux builds?
If you can disconnect the drives, that would be the safest option during the Zorin installation.
There are other linux distributions which are less ressource intensive, e.g. all distributions with a XFCE or LXQT desktop or just window managers.
If you are looking for a lightweight distribution, take Zorin Lite instead of Zorin Core.

When You have multiple Drives, You have during Install the Option ''Something Else'' where You can set up the Partitions manually on the Drive You want. Alternatively, You could do it like @Forpli wrote and simply disconnect the Drives. A Point could be: Do You want create a Dual-Boot System first or directly wipe Windows?
Games can be a bit ... difficult. Do You run that over Steam?
If You mean the Terminal Usage ... Well, it can be that using it is a Way to solve a Problem. It depends a bit how You have to set up Your System, Driver Installation and Stuff like that. It depends on the Circumstances.
