So I'm trying to upgrade to win10 from a fresh install of windows 7. All I have installed are the Ethernet drivers. It's been about 30 minutes or so at 3% copying files and 0% total. I am installing from a USB configured with the media tool given by Microsoft. My case's hard drive activity LED is not active (though I do not know if it would be during an OS change). I've heard it can take 24 hours to finish the upgrade, what should I do? How long should I wait for it to change?
