Thanks!

That usually happends if no boot device is found. Can you confirm there is a detected boot disk with bootloader?

I didn’t change anything in the device, I started it and this happened. Yesterday it was still normal.

Yeah, the SSDs dont degrade same way HDDs do. While HDD dies over time SSD does give some signs it’s near end of it life, but it basicly dies over night.
Now it might be other causes like pc losing power while cmos is dead and resetjng the bios making it bokt to itself, but if you can’t see the SSD in boot devices in BIOS it is most probably dead.
Also you might try using another pc just to make sure it’s not a fluke.

can you send a video of the part that says Boot and the different options? does it let you boot from disk or directly does not detect it? as Aqua said?

it works again, but… we had to install windows 10 because windows 11 made the last update so, that it needs a chipset that isn’t built in. So the automatic update made the device unuseable! I thik this is very strange for a product that we bought with windows 11 on it. A lot of functions are not working now, like “automatic tilt” and stuff.
