I have just registered in this website because I don't seem to find the solution to my situation, so here's the story:
My sister bought a laptop a few weeks ago and it came preinstalled with windows 8, so I immediately suggested to upgrade to Windows 10 which I find easier to use, so I did that for her but the Pc became really laggy and so slow to boot up that I had to configure sleep and hibernation. So my sister told me that she wanted to go back to the original windows that came on the laptop, so I made a backup of the files to another hard drive (I opened up the laptop and extracted the HDD an plugged it in my Desktop PC) and then, used One Key recovery from the laptop (Lenovo) so it has Windows 8 or 8.1 (Im not sure but it does have Start button) So I restored the files from the other HDD but I get a message saying "Access Denied" and "Use the security Tab to enable ownership" and I have actually seen videos on how to take ownership of the folder but with no luck. So I hope you could help me to sort that out, I was thinking that maybe the file system of Windows 10 is slightly different that of W8 because I get sometimes the error "Destination or file is corrupted"
So I am thinking of two possible solutions to this:
-Be able somehow to gain access to folders again and everything cool and good (preferred)
-Clean install W10 and see if I can access the files that way
Thanks in advance, I will attach some screenshots, If you need more please tell me
Happy new year!
