Windows 10: Error code 0xC004003 windows

So I bought a new motherboard and processor and pcu etc. But I kept my old ssd. And when I recovered my windows it lost my product key and now I cant find it either I have used almost every method. There is an error code 0xC004C003 underneath where reads PRODUCT KEY and then there are some XXXX-XXXX-XXXX. What I have to do to activate my windows?

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.

 

Windows 10 will not activate Error code 0x803F7001


Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem

 

error code ?

When did the error code appear? During POST? Was it a Windows bluescreen error?
