I copied most of it to paper, so here it is, for sure with some typing
errors:

Everything up to hear I couldn't read (maybe I find a laptop or other
device for serial communication):

So it looks like my disks are recognized, the partitions are recognized,
but somehow I am missing the

or similar message.

Maybe this helps someone to have an idea!

Best wishes and thanks a lot
