My pc has frozen and when I rebooted I got an HD error 3F0 and a boot device could not be found

[RichardElliott]

HP Envy TE-01 1000na; froze last night, rebooted and got a message boot device not found; please install an operating system on your hard disk. Hard Disk - 3F0. Please help - I've tried all the standard remedies and end up back at that screen. I even changed the motherboard battery and tried to boot from a system disk created on the laptop I'm currently using. Is my SSD completely kaput? or am I missing something obvious?

Greetings @RichardElliott 

The error you are seeing is usually a: failing or bad system disk.

You have tried standard remedies.

Did you run HP Hardware Diagnostics?

Check your PC's hardware using HP Diagnostics as follows:

Start the PC. Repeatedly tap the "ESC" key.

Select "F2". Run extensive system and component tests to confirm: a drive problem, a memory problem, or other component problem.

Let the Forum know how it goes.

I've run all the hardware tests and they all passed (even the extended hd one which ran for over 4 hours). I'm at a complete loss - all I can think is that there is something wrong with the bootloader program - but how can I replace that if I can't even get the machine to boot?

That's throwing me for a loop. A 3F0 error usually means the system disk has failed.

It's almost impossible to check many HP consumer PC specs at this time. I can't find your PC's  specs.

Do you have two storage devices installed in your PC?  Some HP PCs will have a low capacity, fast M.2 NVME, operating system drive and a second larger data HDD.

It may be possible HP diagnostics is only checking the HDD if the NVME drive is cooked. Do you see two storage devices, if your PC has two storage devices, when running HP diagnostics?
