Windows 10: Windows 7 Home upgrade to Windows 10 Home "Failed"

So I finally bought Windows 10 after missing the free upgrade window and of course the installation won't work. I have a valid Product Key for W10, downloaded the media creation tool and have tried several times to upgrade, and each time it goes through the whole installation process before the dialog box opens "Windows 10 Installation has failed" without any error code or other information.

I uninstalled Security Essentials, rebooted between installs, and followed all the advice I've seen and none of it has worked. I loaded the installer on a flash drive and booted with it and it tells me I can't do an upgrade from boot, which makes NO sense as it's one of two options. I don't have an extra 500gb drive lying around to backup my work and do a fresh install of W10 either.

I am a competent computer guy, this is my third self-made desktop, but I'm at my wit's end here. Any advice?

:)

 

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

i've seen this when the stock USB drivers went kaput. Only ever seen it once - i used a PCI USB 2.0 card and connected the mouse and keyboard to that, and manually updated the USB 2/USB 3 drivers.
