Windows 10: Windows 10 Pro doesn't reactivate after hardware upgrade

To start, I'm using a retail key not an OEM one. It was originally for Windows 7 Pro but I upgraded it to Win 10 Pro years ago and it's been working fine all this time. The key came in a physical sleeve and were sold to me by an official "Microsoft Gold Certified Partner".I've tried everything, the normal activation process via my Microsoft account. My old computer shows up but when I select it it says the key was already used yes it was, for this computerI tried to insert a screenshot here but "something went wrong" and it refuses to insert the image. You can see the screenshot here https:/

Activation of Windows 10 Pro doesn´t work

Hallo, i can´t activate my windows 10 Pro (free upgrade from windows 7);

Info: 0xC0EA000A

Manual activation doesn´t work either.

Important (i think): I had to re-install windows 10 (3 or even 4 times). because I had massive problems with "Start and Cortana Issues".

I hope, I don´t have to search the old product key.

PS. Yes, Windows 7 was genuine.

 

Windows doesn`t start. Authomatic repair doesn`t work.

Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

I ran SeaTools. These are the results:




Does it mean my HDD is useless?

 

Reactivation Windows 10 Pro issue

I have changed my hardware recently and found that I can't reactivate Windows 10 Pro. In Reactivate Windows section, I can't find my current device in the list, only my old motherboards appeared ( MSI and Gigabyte ). My old hardware are I7-4790 + MSI H81M
Mobo + 8GB DDR3 Ram and I upgraded to I5-9400F + My new Asrock MOBO B350 or 450 something (Can't remember) + 16 GB DDR4 Ram. There is no my current MOBO in the reactivate section, only the old one appeared (MSI H81M Mobo). Pls someone help me.

Also note that I have signed in with my microsoft account that links with Windows 10 pro licence but it only shows the old mobo in the reactivate list.
