Boot Device Not Found???

Hey everyone,

I have a HP Spectre x360 13 inch model (2018). I was trying to boot up my laptop until this screen appeared. It seems that if I force shut it down (pressing on the power key) and turn it on again, it works fine. I'm worried on the condition of my laptop, what should I do?

PS: I have a warranty FYI.

Win10 has enabled a new hibernation process known as Fast Startup -- which is different from Fast Boot. This is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. This could be what is happening to your PC.

Disabling Fast Startup might fix the booting problem.

There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.

Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup

Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F

In both cases, reboot Windows.

NOW, FastStartup is disabled.
