I am using all in one hp eliteone 800 g1 AiO having core i7 4770s processor, my pc works good but when i turn on the pc it doesn't boot from hard drive, a blank screen appears with cursor blinking on upper left corner, then i have to restart it by pressing Alt+Ctrl+Del and pressing F9 continuously for boot menu and then select hard drive, then its boot from hard drive, I have windows 10 in my pc.
In Bios setup hard drive is set as first boot device, i tried too much in bios but unable to boot directly from hard drive, my bios version is
BIOS Version/Date Hewlett-Packard L01 v02.21, 17/12/2013
 


What was the last thing you did before this happened?
 


CMOS? You mean a CMOS reset?
BIOS update?

Hows about we determine the actual issue, before going down strange pathways that probably have nothing to do with this.
 


Yeah I meant CMOS reset, and as this steps take a few minutes and they might help I thought they were a good thing to try out, sorry anyways. =(
 


And as a BIOS update is one of the more hazardous things you can do....let's see if that is the actual problem first (it isn't).
 

Okay sorry =(
 


I updated the bios to latest version of 2018, previously it was 2013, but it doesn't work, but minor improvement is that now instead of pressing F9, i just press ESC key and then its boot from hard drive.
