I am getting bsod critical process died . I tried everything to fix it. Now when I boot it says  no operation system installed. My HDD is SHOWN in bios and was wondering if HDD or motherboard is failing.Any suggestion would GREATLY help. I also reset bios to default.   I updated windows 10 9 days ago and it started to be very unresponsive 1 day ago .when OneDrive loaded I noticed that windows wasn't responding properly.. When I end tasked OneDrive computer worked fine. One day ago the computer started to become very slowly so I proceeded to sign off and back on . The computer became black and I had to turn it off. After I started computer again I GOT the bsod critical process died. I tried everything up to few hours ago I got no operation system installed.Sounds like the HDD is failing...
RUN the diags from the HDD manuf. site,Can't boot into windows no OS found.The diagnostics run from a bootable media you create... info on doing so will be at the drive manuf. site.
