Hard disk 3F0

[Vanessa125]

All the sudden my Hp laptop just turned off and took me to a Boot Devise not found screen.

 It tells me to please install an operating system on my hard disk.

 Hard Disk (3F0)

 Also gives me an option for a system diagnostic by pressing (F2)

 Does anyone know how to help me. Do i need to buy a new hard disk or just a new OS? someone please help me i cant do anything on my computer now... thanks
