When I install Windows 10 it gives me a hard disk error every time I reboot. I have to run the quick test, which passes, every time I reboot. I had my computer professionally serviced and they told me there was nothing wrong with my hard drive, that it passed every test. I totally restored my computer to factory condition with Windows 7 and reinstalled all my programs and data with no problem. The when I upgraded to Windows 10, I keep getting the hard disk error every time. It's annoying having to run the quick test every time I reboot. Anyone have an answer to this problem?
