Couldn't proceed with installation because Windows installer for some reason disabled my USB mouse and keyboard. Unplug/replug into any of the 10 ports on my system did nothing to change this.

Now I've plugged in an old IR keyboard that uses the PS2 ports (and doesn't require drivers). Waiting to get back to the same point in setup.

The next reboot will be to run some of the tests you guys linked, which I'm about to download now.
