Booting device not found - SSD visible in Bios but not in windows installer

[VH2000]

OK, it is like I expected.

So   n e v e r (!)   change your system to LEGACY again!

The SSD is lost. It can be disk 1

What you can try now: Remove the SSD and plug it in again.

Then use 3rd party tools to check if it can be fixed.

But the problem was there before I tried to switch to legacy.

I did witch back to UEFI.

This said, if the legacy created this problem, then why is the SSD seen by the Bios when in Legacy mode?

This said, if the problem actually comes from the Bios and how it sees the various disks, would it make sense to try to update the Bios now?

I notice on HP driver support that my Bios version F.10 is pretty old one

It's more than urgent to get your BIOS updated. But you need a second computer to prepare the USB-Stick.

Usually I use LINUX and "testdisk" to fix disk problems. 

Take out the SSD disk and try to get it repaired with a second computer.

Could the new BIOS change the situation?

Is it possible that with the new BIOS I could see the SSD?

I do have another computer from which prepare the USB stick with the new BIOS, but I don't have another PC were to connect the SSD, assuming I would be able to unmount it from my laptop.

But let's assume I manage to unmount it, what shall I do?

I do have a very old laptop, but I don't think I can attach the SSD there

Anyhow, if the problem is hardware, I would maybe first try to change the connector, what do you think?

The SSD is detected in BIOS and by Windows installer as disk 1!

You need an adapter USB ==>M.2

When you remove it from your Laptop you see if it has 1 or 2 Slots.

1 Slot means NVMe

2 Slots means M.2 SSD

It is possible that Windows detects it on a 2nd computer and runs a chkdsk.

If you see the Manufacturer you can check the homepage for troubleshooting software.

HI

when I launch windows installer I see a Disk 1 with 0 memory allocated.

Do you think I can try to install windows there?

I guess it should fail.

2nd option

Do you think it could make sense to try to install Windows 10 on the 1TB HDD ??

Once windows installed on the HDD, I can launch it from there and maybe there could be a way to fix the SSD from Windows, what do you think?

I do have 300 GB of data in the HDD, is there a way to install Windows 10 from scratch on the HDD without erasing those 300 GB of Data?

All this, shall I still update the bios first? or is it better to limit interactions now?

No, no, no!

1. You should not try to install Win on disk 1! It will fail!

2. What happens if your installation fails? Do you want to risk that all your data get lost?

Update your BIOS first.

Hi

an update.

I managed to open the laptop, remove the SSD and plug it to another pc via a usb adaptor.

The SSD seems to work fine, I could even open files without doing anything specific, simply using windows explorer.

In this situation does it also sound to you that the problem is not the SSD itself?

I can still run a chkdsk, or format it, but is it possible that the problem is instead in the bios or in the connector?

And if the problem is the connector, how can I solve it?

It's not the connector because it is registered by the pc with a size of 0 MB
chkdsk is a good option. 
Can you start the 2nd pc with the SSD connected by USB and open diskmanagement?
There you scroll down to the USB disc and make a screenshot. I have to check that first and see the partitions.
