So, my sister wanted me to fix her HP notebook laptop. It was Windows 10. I can't fix it. It started as not able to click on the icons, or access the start menu. I tried to do a restore, (maybe it was an update) didn't work, among other things under the troubleshoot menu. Nothing was working, it kept saying "failed." So as a last resort, I tried to reset the PC. Still said it failed, so everything was as the same. Suddenly, I got a black screen saying "boot device not found lease install an operating system on your hard drive."
I've hit the F2 key and did a hard drive check, the quick one says that the SMART Check passed, but the short DST failed. Then on the extensive one, I get the same information. SMART: Passed Long DST failed.
I don't know what to do now. Thanks!
