Default Boot Device Missing Or Boot Failed Lenovo Yoga 920 13Ikb
Chosen Solution Thanks. I tried the restart you mentioned with the side button and disconnected the main battery. Many times. It does not work. I googled and it seems disconnecting the cmos battery for a few minutes helps. That is why I wanted to try this. How do I fix the error “default boot device missing or boot failed”? This happened to me a bunch after I first got mine. I eventually sent it in to get it fixed, but for a long time I would just… wack my laptop against my knee, or otherwise hit it, until whatever was on the inside (the SSD, I suspect) wiggled back to where it needed to go....
