Hello, I am using the Hp laptop and getting this error message.

I have checked the hard disk it by attaching the hard disk as a USB with another computer, I properly show the files.

Please help me out.

Boot device not found. Please install an operating system

Laptop :hp probook 4540s

Os : windows 10

I turned off my laptop using power button and after that this error pops out "Boot device not found please install an operating system error 3f0"

This problem occurred the second time, at first time it was fixed by someone who is not in this world.

So I am damn sure that my hard disk is in perfect condition.

Your help will be highly appreciated.

Thanks in advance!!
