Install Disc 0xc000021a Error

So, my hard drive recently went out on my computer. I'm broke, so I pulled a hard drive out of an old computer my friend gave me a couple years ago. That hard drive has a non-genuine copy of windows 7 ultimate edition. The previous hard drive had Windows 8.1, and I have a valid product key for that, so I figured "Eh, what the heck. I'll just install 10 and use my Windows 8 product key to validate it for the free upgrade."

Now, the problem becomes that the copy of windows 7 on the hard drive is 32 bit, and the rest of the computer is built for a 64 bit OS, and I don't like the idea of not using the full capabilities of my system. I've got 8GB RAM in here. Only using half of it feels horrible. So I'd like to get 64 bit Windows 10. I went and downloaded the iso through microsoft's media thing, then burned it to a DVD5 using a separate tool called imgburn.

However, when I boot to the DVD, the blue, flat windows logo shows up, it hangs for awhile doing nothing, the spinning dots show up, then it immediately crashes, giving me a blue screen.

The blue screen has the frowny face and the "Something went wrong" and the error code 0xc000021a. A bunch of googling shows me a whole lot of problems with the system on boot, but nothing at all related to installing windows 10 and getting that error. Microsoft's site has been less than useful, only telling me that there was either a problem with WinLogon.exe or csrss.exe, with no information about how to trouble shoot that problem.

I've tried making more copies of the disc (I'm out of DVDs now), and I redownloaded the iso and switched burner programs for the final disc.
