OS Not found

[Jspicer83]

I received the Hard Disk boot device not found error this morning. I tried to hard restart the computer, I ran all the prompted diagnostics test which came back with passed results. Even trying to run it in Legacy does not work. Please help.

You pressed F2 and run disk diagnostics it is passed.  Possibly the boot sector is corrupted.

Go into the bios setup and select defaults.  Ensure secure boot is enabled and the date and time are correct.  I assume windows 10 or 11.  Try booting into safe mode and see if you can do a startup repair

To do a startup repair you need boot into windows recovery mode. First read this article about safe mode.
Skip down to 'Enter safe mode from outside windows'. If f11 does not get you into system recovery then try turning the power on and off three or more times in a row.
When you get to advanced options select 'Startup Repair'

If the startup repair fails then try the restore point.


This video describes how to use a restore point.
Let me know if you need more help or if startup repair fails.
