You only need to boot from the usb device if you are doing a clean install. That will only affect a minute proportion of Windows users. The downloaded upgrade will run from your existing Windows to do an upgrade of your current installation. I've done this on all the Insider releases and the final releases, and this release, on four different computers without any problems - one laptop, three desktops. As far as I am concerned, the days of clean installs are past thank goodness!
