Typing this with my phone so apologies if this message is typed poorly. Was transfering a couple big video files from my boot drive to my second SSD drive when I noticed the transfer bottom out. Whole computer froze with a blue loading circle then I got a CRITICAL_PROCESS_DIED BSOD and upon reboot the it went to the “Reboot and Select proper Boot device” screen. Hit the reset button on my PC case but no luck. Went into the BIOS and only drives I see in the boot list are the UEFI network controller, my secondary SSD, and my HDD. Boot drive is completely gone. Don’t know what to do.
