Installation Key from a OEM Product Key
 

I'm doing some work for a mate where his hard drive crashed like it just had a chest grabber and all he has is his product which doesn't work as an installation key.

When I click on "I don't have a product key" the Win10 installation process won't let me go any further as it simply states I need one. But all I have is the product OEM key which is 20 characters while a product installation key is 25 so install won't take that either.

Does anyone know a way to attain the installation key from the product OEM key or a workaround or do I have to suck it up and wait until morning and call MS?

TIA

There should be an option to "Do this later" at the part where it asks for the key. What version of Windows are you using to install?

1. Pirate Enterprise Edition
2. Profit

I couldn't get that to work. I'd choose "I don't have a product key" it would install the files then bounce me back to the beginning. After rebooting a couple times and remaking the USB install tool it worked.

That was a weird first.
