Windows 10: Can't upgrade to Windows 10 Pro from Windows 10 Home

Hello,Recently in my job I received a new laptop with Windows 10 Home already installed on it. I also received Windows 10 Pro OEM DVD disc.I tried to upgrade from Windows 10 Home to Windows 10 Pro using Activation screen and "Change product key" option. I tried entering the Windows 10 Pro key. However, I received following error: "Provided product key is not working. Check product key and try again or enter different product key 0xC004F050"I tried using generic Win 10 Pro Key VK7JG-NPHTM-C97JM-9MPGT-3V66T with no luck. I got same error as above.I also tried full reinstallation of Windows 1

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.

 

Windows 10 Release Date Announced

Windows 10 Home will be $119, Pro $199.

Microsoft: Windows 10 Home costs $119, Pro costs $199



Which is good news actually, because Windows 8.1 is loads cheaper than previous versions (retail licensing at Windows 7 OEM prices). And it sort of puts a huge hole in the Windows subscription theory.

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.
