So I'm building a new PC. I have Windows 10 Home retail version on the readonly USB stick. At the beginning of the install process I'm getting the error message "Windows cannot read the <ProductKey> setting from the unattend answer file. Clicking "OK" reboots the machine.
I don't see a way to enter in my product key. I'm not trying to do an unattended installation.
I've read where I'm supposed to download an ISO file and create a bootable USB Key or DVD but I don't have a spare USB key.
