Try resetting your BIOS defaults:

If that does not work and you have a desktop computer...
Power down
Unplug it
Open the system unit
Remove the CMOS CR-2032 battery
Plug it in, start the machine, wait 10 seconds
Power down, unplug it, reinstall the CMOS CR-2032 battery
Plug it in again, power up
Check if the keyboard works.
If that does not work, I recommend you perform a custom install instead.
From another working computer, download and make a bootable copy.

Setup will also prompt you to select the edition you have a license for - Home or Pro. Please make sure you choose the right edition. If you choose the wrong edition, your only option will be to perform a clean install again.
The copy of Windows 10 you download and upgrade from will correspond with the edition of Windows you have installed, if it does not, this is why you might be experiencing problems activating:
Windows 7 Starter, Home Basic, Home Premium, Windows 8.0 Core, Windows 8.1 Core should install Windows 10 Home
Windows 7 Professional, Windows 7 Ultimate, Windows 8.0 Pro, Windows 8.1 Pro should install Windows 10 Pro

Wait while Setup starts.
