Windows 10: Win 10 Pro and Win 10 EDU installation on same SSD

I'm a member over at eight forums and have just registered here, hello!

Windows 10 Pro was/is my default operating system - I've just installed Windows 10 EDU on a different partition on the same SSD. (One install needs Java 6 update 6 where my work systems use them. The fresh install requires the most recent Java version for IDEs to function correctly.)

Purely a question for my own benefit, some could argue it's trivial: The partitions that I've filled with a yellow colour shown in the below image - do they serve both operating system installs, and (low level answer welcome) why?





Many thanks!

Windows Hello

It's an acer TravelMate B117. It had Windows 10 Pro Edu, but i installed Win Pro with license (Before changing edition it not worked, too.)

 

Windows 10 Pro activation error

Approx two years ago I did a free upgrade on my laptop from an activated Win 8.1 Pro to Win 10 Pro. I then easily activated the Win 10 Pro.

Recently I needed to do a clean install and at the same time upgraded to a SSD.

After installing Win 10 Pro from a backup, I attempted to activate and received the following:

"We found a Win 10 Pro digital license for this device running Win 10 Pro.

To activate using this digital license you need to install Win 10 Pro."

"(null) Error 0xC004F034"

Really?????? Win 10 Pro IS installed!! And the install runs fine.

The only thing that is changed is the HD to SSD.

The digital license is supposedly tied to this laptop!

I can't find any phone support. What now????
