Windows 10: Windows 10 Activation key doesn't work after reinstall

Hello, I have bought a laptop with Windows 10 Home Edition pre-installed. However, due to a problem with the lapton I sent it to be checked in the dealership, where they've decided to test it using a test Windows image. At this point I am running a test version of Win 10, and when I try to enter my original activation key, it is not recognized. Can you assist with this? Thanks in advance.

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?
