I had the "Default Boot Device Missing or boot failed" issue. However, upon entering the bios I was unable to change the boot mode to legacy. The boot menu only offered options to enable usb boot. Also, the computer crashed a showed a blue screen before sending me to the boot menu.
This problem happened before, but I was somehow about to get out of the menu. When I did get out, I couldn't open file explorer.
I have ayoga 920.

my best guess is that the SSD is failing.
