I successfully downloaded and began the install about 3 hours ago. everything went fine until it rebooted. It has now been on a page that says: "Preparing to configure Windows. Do not turn off your computer"...for two and a half hours now.
What do I do? Do I wait longer?...The animated circular icon that shows that the machine is working is still spinning, so I don't think it's frozen...I also occasionally see the HDD LED flickering indicating some activity...but it's just been way too long now.
