My 5 day old HP laptop has started to randomly decide that no boot device exists.
Blue screen error:
Boot Device Not Found
Hard Disk - (3F0)
F2 - System Diagnostics
For more information visit... http://www.hp.com/go/3f0harddiskerror
F2 doesn't work from the error and following the information on the link passes Proceedure 1.
However, for proceedure 2, Legacy Support is knowhere to be found - so you can't disable it and therefore can't get to proceedure 3 to check the Optane memory.
I've carried out all the hardware and software updates and ran all the hardware and software checks I can find... all of them come back OK/Green.
The issue seems to occur most when left open/inactive for a short period. However, there is no consistency in the time delay.
A hard reboot restarts everything as normal.
Any ideas?
