Thanks for the info, so the HW is quite a bit older than what we tested.
Boot to the initial installer grub menu.
There press the
e
key to edit a boot entry (e.g., the Graphical one)
Use the arrow keys to navigate to the line that starts with
linux
, move to the right where the
quiet
parameter is, delete that (so we maybe get a bit more info) and add
nomodeset
there, just as the screenshot below:

Then press
CTRL
+
X
to boot.
So potentially an issue with the newer kernel, hmm maybe we can get some hands on such old NVIDIA GPUs somewhere.
