so i was using my pc fine this morning. decided to reset and got this message "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key" i went into my bios and my primary and secondary slaves are not detected. my boot priority is still to boot from an hd but i dunno what is going on? i formatted an external hd from fat32 to ntfs but dont see how that would affect anything? i opened up my pc and none of my cables are loose and no bios settings were changed what would cause my pc to do this?
