So I have a laptop that originally came with Windows 10 home. I want to install Windows 10 Pro, I have license keys for Windows 10 pro, but The Windows ISO installer defaults to Windows 10 home when booting from the ISO.. How do I bypass that automatic install of of 10 home and do a clean install with a refurb Windows 10 Pro license? I am an old school Microsoft registered refurbisher. I have Windows 10 Licenses, but if I boot from the Windows 10 ISO it automatically installs 10 home because that is what the machine is originially licensed for. If I put in the 10 Pro license on the upgrade license screen it says it can't activate the license, but I have tried with 3 license keys so far and those activated just fine on other machines... just not this one.. how to bypass and put in my own license key?
