[What please means PCI-E 2.0 x8 port #2 Belegt @ x8?]

After replacing an internal NVMe SSD drive in a HP Pavilion notebook neither the new drive nor the old drive is recognized. Unfortunately, this was the start drive. 

I want to find out what happened during the first start try via the replacement SSD clone which ended unsuccessful (and the following starts from this port too).

Could it have been a connection failure of the slot or was the firmware tampered?

You find a report of the Intel SSU attached to this message.

I have copied also some fragments of the Aida64 report (see below), Could possibly some conclusions derived?

Is there a tool for a more detailed investigation?
