SSD not beeing recognized

Hi

I have just installed a Samsung  850 EVO 250 GB ssd in my Mac Mini (late 2012).

I have created a boot disk on an external Toshiba USB HD.

When I boot the USB HD to install the newest OS  Sierra, I cannot see my drive anywhere.

I have checked the cables 10 times and all is a fit. Any ideas?

=== Update (10/02/2017) ===

Thank you for your reply.

I am replaceing the internal 5200 RPM HD with the SSD.

Once I put the original drive back in - everything works (it boots the drive).

The external HD with the install partion on it is - unfortunately - just an external HD with not possibility to swap the disks out.

Is there a way of testing if the SSD is faulty? Could it be an issue that I boot from an external HD rather than USB? Could it be that I need to update the firmware?
