Trying to upgrade to Win 10 Pro

I have Win 10 Home on my Lenovo laptop. I bought a Win 10 Pro For OEM software pack to upgrade to Win 10 Pro but my system didn’t accept the 25 character prod key. What should I do?

I’m trying to install the upgrade via DVD (which came with the pack) but I noticed it said during the process that it would install Win 10 Home on my laptop but I already have that. Any suggestions ?

 

Fresh Install of Win 10 without Serial Key?

Looking to reformat a laptops HDD, and then reinstall Win 10 fresh. The problem is it came pre-installed with Win 8 and I did the free upgrade to Win 10. How exactly would I re-format the HDD, reinstall Win 10 and ensure it reactivates properly? I don't see a Win 8 serial key anywhere in the contents of the box.

 

Upgrade a Win 10 home OEM to Win 10 Pro OEM with Win 10 Pro OEM Key?

I recently purchased a laptop that has an OEM version of Win 10 Home on it.

I verified this by using : slmgr -dli.

Previously I had purchased an OEM Win 10 Pro Key.

Can I use this OEM Win 10 Pro Key to upgrade the OEM Win 10 Home to the OEM Win 10 Pro.

If so what are the steps to accomplish this?

In addition, I assume that is this is possible, that the current product key will be updated to the new product key?

The reason I am asking this is that it's my understanding that these product keys are tied to the bios on a name brand laptop.

TIA
