Windows 10 Question

[Viscian]

Hey guys/gals,

So I recently built my dream machine. I installed Windows 8 on it. I truly regret that decision. As soon as I could I did the Windows 10 upgrade. I've realized I hate it also and want Windows 7 back.

I want to completely remove Windows 10 and install Windows 7 OEM on my system. However, the only searches I found thus far would be to downgrade Windows 10 back to 8 or to 7 if it were previously installed. This is not my case.

I did find a thread regarding partitioning but I have no idea how to do that and I really don't want to have both 10 and 7 on my computer.

So my question is really. How the hell do I completely rid myself of Windows 10/8 and install Windows 7?
