I'm trying to do a clean install of Windows 10 on my laptop. I used the media creation tool to create a boot flash with the windows 10 installer. The media creation tool gives me three options none of them is windows 10 pro. However upon booting my computer the installer starts up, I choose language, time and keyboard input but it doesn't ask me for my key or what version of Windows 10 I want to install. It goes directly to install it and once it's done I end up with Windows 10 home. And when I'm doing the setup it never asks for a key. I've tried upgrading from Windows 10 home to pro but it always fails and reverts changes. Any help would be appreciated.
