There should really be another section for Windows 8.1 specifically, since in its own rights and the way that it operates, it's not just a simple update, but an entirely different operating system. Anyway, to the problem.
After days of scouring the internet, I've come up with nothing really for this specific problem. Now, this computer is just about a year old, meaning that it came with an original copy of Windows 8.1, it did not start with Windows 8, just to clarify. Now, the HDD went bad. Of course, being the typical consumer, said laptop had never had any recovery media created. However, I have managed to recover the OEM BIOS product key (which was different from the key I used to activate a copy of windows to reach the desktop to do so.) Regardless, the key does not activate when I put it in on a copy of Windows 8.1 64bit, saying that it couldn't activate this version. So, I created media for Windows 8.1 32bit (which I was pretty sure it was not a 32bit copy, but eh, why not?) During the activation (which the media should automatically detect the product key when installing, just as a Windows 8 clean install from Microsoft will) I entered the product key when it prompts. It tells me that this installation media does not have any files related to this version of windows. I tried the 64 bit version again, this time using my OEM key. It says the same thing. So, what version of Windows 8.1 did this computer have? Was it an enterprise edition or something? Is there any way that I can tell what version of windows the product key is? Because apparently the bootable installations can.
TL;DR
HDD went bad, not bootable, no recovery media. Got new HDD. I have the OEM product key, which is Windows 8.1. The standard retail Windows 8.1 32 and 64 bit installs say that I can't use that key to install them.
