You're wrong on pretty much all assumptions you've made above...but the high level idea is this:
 
1. Go into windows setup,
2. Pick the drive you want to install Windows on, format the drive first, (thatll wipe the data). If you want use the format tool to format the other one too..
3. Install windows. Win. Profit
4. Install games where you want..

 
Moving to General Hardware.

I have just started with this computer, I bet it hasen't been up and running a full month yet. So, the point is I dont really have anything on this rig yet. I think I should stop the bad start that I did, and before I get to much deeper, and really get some important stuff on this machine, I want to have it set up right. Yes, I made some mistake setting it up, but I did learn from them ( I hope) LOL. And yes, I have a compyter guy that used to do all of my work( and charge the hell out of me for every minute), and I would just help him a little and try and watch and learn. That was 5-6 years ago and I havent been doing it since, as far as staying up to date on new hardware and software, or doing any building, because I didnt have money like I did 5-6 years ago. Now my money is better so I want to get back into what I started to learn 5 years ago. Bottom line, I really want to learn. I'm a 43 year old man who loves building high end rigs, playing BF4 and 3 and benchmarking and testing. Some people hunt, some fish and I love building rigs and learning about computers. Even if I make some mistakes, anything is fixable, and the way I look at things, sometimes you have to make mistakes to learn. 
 
 
Thanks for your input though

I started everything over, and I have 2 blank drives, but no matter what I tried, it would not let me load windows 10 on my 2nd drive ( the 850 EVO 250 Gig). 
 
I started with the PNY 240 because it was supposed to be quick, after I loaded a few games and CAD I was at 13% free space, which I know wasn't good. Since the rig is so new and didn't really have a lot on it yet, I decided to make the switch now after I got the 850 EVO. A bunch of people said don't run it in raid, just use it as a standard drive. So I added the 850 as a "Dynamic Drive D"  <~~~~~~ I think this is the problem. then I learned the 850 EVO is way faster then this PNY, so I was going to make the 850 EVO the main drive with the OS and few games only, everything else, CAD, Office, and all other docs, songs, pics, and videos, basically everything else. 
 
So my plan was to wipe both drives clean ( I already backed up what I had to have on a thumb drive). I reformatted both drives, wiped both clean but no matter what I changed in the bios or windows, it wouldn't let me load windows on this "D" drive the 850 EVO. I tried a million times 
 
I'm very "dumb" when it comes to computer stuff and one of my buddies has a shop and he will help me, but he will charge the hell out of me for it, + I just want to be able to say I did it, maybe have to say it was with a little help from you guys, but still, I did it on my own!!!! 
 
Anyway, I loaded windows back on the PNY because that was my only option but all I have done, is windows, display drivers, and AVG so I dont get anything, trying to get back on these forums so you guys can help tell me how to get this "dynamic D drive to accept windows?????
 
 
 
I'm so lost and frustrated.... Grrrr 
 
Let me know what you guys think. I'm going to leave it running empty like this I'm not going to stay with this PNY because Windows is telling me to, to heck with that, I tell Windows what to do. LOL
 
 
Any help would be greatly appreciated!!!!
