I know this is a fairly common error but I have not found a thread with a similar circumstance...
Reboot and Select proper Boot device - can’t fix
My wife’s computer randomly got this dreaded message upon boot up. There are two SSD’s - one 256 GB with Windows 10, and another 500 GB for additional storage. I figured the 256 GB had failed, although both drives were detected in BIOS, and the boot priority was correct. I tried removing the 256 GB and installing windows via USB stick on the 500 GB drive, and it seemed to install windows correctly. However, once it got to the stage where it reboots after installing windows, it goes right back to the original ‘reboot and select proper boot device’ error upon startup. That pretty much exhausts my ideas on what to try, so I need some suggestions. I doubt both SSD’s failed simultaneously. Thanks in advance!
