ssd I want to boot from can't boot without other hard drive connected

Hello all
I had windows 10 on hard drive G. Then, I clean installed windows 7 on hard drive C , an SSD. Before all of this I had other hard drives that H and D ( same hard drive , partitioned) , I don't remember how or why I partitioned the old ones...

Now, I wanted to delete win 10 from G, but i read sometimes that when you install like I did, the new windows boot process needs files from the old hard drive. So to test this I disconnected the old hard drive (G). I couldn't boot. So I reconnected the old hard drive, and still couldn't boot to windows 7 on the new ssd (C), however it would boot to the old windows 10 (G). I finally put in my windows 7 disc, and let it run a startup repair, this recovered my windows 7 on C.

So here I am, and I want to completely wipe hard drive G, and make my primary, and only booting drive, hard drive C. possibly also un-partition h and d , make it just be one drive.

Also, just for clarification, I would like "disc 2" to be my primary boot drive.

Thank you, However I just realized I linked you the wrong screen capture, and I left a small piece out of the last story, however but maybe this will help. "Now, I wanted to delete win 10 from G, but i read sometimes that when you install like I did, the new windows boot process needs files from the old hard drive.

OK, so at this point If I remember correctly I took the screenshot above. Being the genius I am I decided to try a fix following this a you tube, I opened the command program and typed some stuff, then marked my ssd C as active and rebooted, this did not work, I couldnt boot so i put the windows disc in and repaired again. now my partition looks like this.
Unfortunately I'm running to work now and I cant find the you tube guy I followed. I will post later when I get a chance, for now, here is what my partitiopn really looks like .

Thank you guys!
Ya I felt really dumb when I went back and reread my post and saw the pic I posted! I will give this a try.

OK, I followed the directions, and it told me that C is already the boot drive (something like that) , and it told me to pick a different drive. So I restarted the computer , and it gave me a prompt to start windows 10, or 7. I chose 7 and it is currently disc checking stuff before boot.

So ya, on reboot the boot manager asks me if I want to load windows 7 or 10.

EasyBCD says that C is already the boot drive.
