This appears on the screen: Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key Ah, ha, ha -- I figured it out. The tech at Gen Nano had left the Nvidia RAID (fakeRAID?) enabled, and that was screwing it up. With RAID disabled, it sees grub and it boots. After that it does not go to Gnome -- it just goes to a console text prompt. Any idea why I don't get gnome?

Previously, holding down the shift key had no effect because it didn't get that far. Now it boots, so maybe it doesn't matter anymore. Mike
