Yesterday I moved the location of my PC. I had disconnected the monitors before shutting down and thought I'd be able to force a shut down by holding the power button. After around 15 seconds the PC turned off. I now come to turn the PC on and get a Reboot and Select proper Boot device... message. I have an MSI motherboard and so I enter the BIOS to try and select the M2 drive that the Windows OS is installed on. No matter which disk I select I always get the same Reboot and Select message. Does anybody have any suggestions as to what I can try? LMK if I need to provide additional info about my system. Thanks!
