The m.2 slot seems to be working, its hard to explain how i know it is...
When i boot it goes to bios cuz it cant find an operating system cuz its on the m.2.

How did the operating system get on the m.2?

Try disconnecting the other disks and boot into BIOS to see if the m.2 is being recognized.

did you install the os on this system? or was it install from another system

Solution:
We took out all the sata and m.2s and connected only the ssd. It recognized it (the m.2 is the one with the operating system). We added one of the hdds and bios couldn't detecte it so we removed it (the hdd). After that we tried adding the m.2. the bios recognized the ssd and the m.2 successfuly with the operating system. We tried connecting the hdd once again, which did not work, concluding that it was the issue. We will try getting hold of the files inside the hdd but that is pretty much it.

Thanks for your help guys
