Windows 10: Help please, I can't get my pc to boot after moving my OS to my secondary hard drive to...

I copied my OS to my bigger secondary drive so I could free up my small ssd for the games I play to help make them maybe a Iittle bit faster and now my pc wont boot. Not even when I take out the ssd and have the hard drive first in the boot order, I've tried everything I can think of with no luck and I wanna pull my hair out now because everything was working just fine before all this

Wiped Hard Drive Can't Boot Vista

I did try every possible boot order and even with deactivated options, which I don't even know how or if that is helpful. I will try the Vista possibilities. The OS was listed in the BIOS, whatever that means, and it said it was a factory version, which I think is a good thing.

The PXE error messages may have occurred when I activated the network adapter and tried that in the boot order. Obviously, I am in way over my head. Thanks for the suggestions!
