Uncle's pc won't boot, can't access valuable data on different pc

[AFCYouri]

So here's my problem, my uncle brought me his pc and told me it stopped working. So after a cleanup I turned the pc on and it brought me straight into the BIOS. The pc has 1 ssd where Windows should be installed on but when booting of the ssd it doesn't bring me to Windows but just goes back to the BIOS. So I think the best or only thing to do is to do a clean install of Windows, now the problem is that my uncle has valuable data on the ssd that he REALLY doesn't want to lose.

I've tried plugging the ssd into my own pc and see if I can somehow access the data and back it up to a different drive, but the drive only shows up in the BIOS and not in disk/device management.

 

So my question is what can I do to either get tot the data and back it up or get the disk to work again on my uncles pc without losing all the data?

Sounds like the drive is dead.

Grab a USB dock for drives, see if it works that way. If not, the drive is likely toast

Does the SSD even show up in the BIOS?

Yes it does show up in the BIOS, this is why I assume the drive isn't dead. But I don't know if a drive can be dead but still show up in the BIOS

if it shows up in BIOS, it shouldn't likely be dead in theory. Is it a 2.5 inch or m.2? if a 2.5, try moving sata ports its connected to and try a different sata cable. If its an m.2, try moving m.2 ports if there are others available.

try a live USB operating system that is linux based.  This will allow you to boot to a OS and the linux won't care about things like file permissions or other non-sense.  Did he encrypt the drive, maybe?

It's a 2.5 inch ssd. I tried plugging it in different sata ports and using different sata cables but still the same problem, it won't boot on my uncles pc and it only shows up in the bios and not in windows on my pc

I don't think he encrypted the ssd. I assume he used the pc like he normally does every day but from 1 day to the other it stopped working

I've seen this before.

My grandpa's architect firm had an 850 EVO 250GB just completely erase itself out of the blue.

He gave it to me, I opened Disk Management, and it showed as initialized, just not allocated.

You'll need to reinstall an OS on it.

just boot from live Linux CD or USB and see if you can access the drive I don't think you need any prior knowledge for that other than how to navigate a computer.
