Hi My laptop about a month ago my laptop came up with the error "Boot Device Not Found Please install an operating system on your hard disk. Hard Disk (3FO) F2 System Diagnostics", and then tells me to go to this website for more information. I've also checked if the hard drive is securely in place and plugged in, I have an HP Envy dv7-7240us laptop and it had an operating system of windows 8 with 64-bit. Please help me, it's urgent!
