Windows 10: Unknown error code

I've been trying to update a Dell Latitude E5520 from Windows 7 to Windows 10, but it has been unsuccessful after 3 attempts. All the files will download and the update will take place, but when it's finished updating, the screen goes black with white text saying "undoing updates" and it reverts back to Windows 7. After rebooting and logging into a profile, An error message pops up saying we couldn't install windows 10, and has an error code 0x8007001F - 0x20006. The reasoning is that "The installation failed in the SAFE_OS phase with an error during REPLICATE_OC operation." I tried to go to the troubleshooting page from the link provided, but that doesn't show the error code in its list of error codes. Is there any way to get this laptop to work completely in Windows 10?

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
