I think I deleted my hard drive by accident and it is the drive which my pc normally boots from. I believe I done this when in bios settings after trying to fix the "reboot or select proper boot device" error on my PC. I deleted my hard drive by accident, now when I turn on my pc the hard drive spins up but the computer doesn't recognise it. I have used a Windows disc and went to repair my computer but still the hard drive isn't there, I have tried changing SATA ports etc but still no fix, can someone help please
