No hardrive found

[Jack2950]

I keep getting boot device not found please install operating system on your hard disk. 3F0.  I'll do f10 and reset default and when it restarts it goes to automatic repair.  I try to do system restore but then I get an error message to restart and select an operating system.

This issue is often due to a failing drive. So, let's check that first, because if it is failing, it would need to be replaced and there is no point then in doing anything else until we confirm that.

If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024

If not, to check the drive you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu
3) Press the Function key for testing the hard drive (usually F2) and let it run.
