Windows 10: installing Windows 10 pro

I want to install W10 pro on a 60GB SSD on small media Pc : AMD E45 UEFI- no legacy. it is a GPT disk used in the Pc for several years. but not in use for a long time. the W10 is expired.
Ihave downloaded The ISO from MS on a DVD but the program stops after a little while with message : efi system partition is formatted ntfs - format the ntfs partition as FAT32 and start install again. (my translation from Norwegian) I do not understand what this means and where and how to do it?
I took the disk out and mounted it on an other Pc (W10). it is not emty as I ecpected due to formatition by the installation program there is 450MB NTFS (OEM-partition)+100MB EFI-system partition+ 59GB NTFS primary partition. I want to format the entire disk, and keep the GPT, but I cant see how to do it. Is this the way to go?

Clean Windows 10 (?PRO?) install

I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.

As far as I am aware there is no Windows 10 Pro version.
But I'd be happy to be wrong.
