My hard drive died in my Inspiron 660. I ordered a new hard drive and a Dell USB recovery key. Dell recommended a recovery key for Windows 8 pro based on my service tag. I installed the new drive and used the recovery key to install Windows 8 pro. I then used a third party tool to get the product key from the BIOS. The product key does not work. I'm wondering if the product key on the BIOS is for Windows 8, not Windows 8 pro. If so, Dell recommended the wrong recovery key.
What do I need to do to successfully activate Windows?
Secondly, on my old hard drive, I had upgraded to Windows 10 when it was a free upgrade. How do I get the free upgrade back?
