I'm making a bootable USB for Windows 10 following Window's instructions here
I have my computer dual booted with Ubuntu 14.04 and Windows 10, I'm thinking about doing a clean installation of just Windows 10 with the bootable USB and wiping everything else. I have Windows 10 already installed, so I should be able to skip the product key step and continue with installation, but with Ubuntu dual booted on my computer I don't know if Windows 10 will ask for a product key or not. (I dual booted Ubuntu after upgrading from Windows 8 to 10)
Will rebooting Windows 10 from a USB work without a product key if I have Ubuntu 14.04 dual booted on my computer? In case Windows 10 decides not to install without a product key, will typing in my current product key work? (I retrieved my product key with a script here)
Thank you for the help! I know it's a newbie question but I want to know before I try and begin the installation.
