So randomly 4 weeks ago I started getting an error on boot that
"Default Boot Device Missing or Boot Failed.
Insert Recovery Media and Hit any key
Then Select 'boot manager' to choose a new boot device or to boot recovery media"
The Acer website suggested that I had to buy a $40 e-recovery flash drive. So I did. It arrived today. Slipped it in, got the same error, followed the simply instructions (hit any key then selected to boot from USB device), and it just loops right back into the same error. What a waste of $40.
