Mac mini mid 2010 stuck on Apple logo with full progress bar

Hello

I bought an used mac mini mid 2010 server. When it arrived I turned it on and it booted regularly into macOS High Sierra, since this is the last version supported by this model. Anyways, I verified that everything was working and then turned off the machine.

The problem is that now it won't boot. The apple logo appears and the progress bar bellow goes all the way to the end, but it does not go beyond that point. I tried to enter into the recover partition and the same thing happens. So it does if I try the Internet Recovery. I even tried to create an installation pen, but the result is the same.

Has anybody experienced something similar? Is it possible to fix it?
