On imac folder with a question on startup. Any ideas?

Question

Solid State Drives

Hello. I decided to break my imac 27 2013 as a gift for ng December 31 (or broke it myself). After starting, it shows the folder with the question. If you go into the disk utility, it shows there disk0 and a 1.2GB macos volume. The check says everything is fine. But I don't understand where the main drive is. If you click "reinstall OS", then the disk selection section is empty. There are no disks.
I thought the hdd was covered. Opened the computer. It turns out that I do not have an hdd, but probably an ssd. Which, as I understand it, is located next to the ports on the back side. SSD from the factory.
Could the ssd be covered? The reason was probably that I left it in sleep mode at night. He started to overload or update something and made a lot of noise .. but the display glowed without a picture, black. I knocked it out through a dream by holding the power button (genius) for a long time.

What could be? What to do? Can you see some logs? Through cmd + opt + p + r threw off.
