default boot device missing or boot failed
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”?
Hi,
Try getting into BIOS and check if the HDD is being detected.
