Recently I came back to my PC after a few days away and upon turning it out it would not boot into windows. I received the srttrail error message "A hard disk could not be found. If a hard disk is installed, it is not responding. So far I have not been able to fix the problem, I am not even able to reset windows as the console says that no versions of windows are installed. In my BIOS, the hard drive does show up in the boot sequence so I am very confused as to why it is not working. Any help would be much appreciated.
