I thought I share some insight while struggels with my Tumbleweed install.
I repeatedly started the install.
This ended like my installed system ( the installation went fine ) but
I only could start the graphical recovery mode.
I tried really a lot of things , including forum proposals in that matter,
Long story short at some point I realized, that the problem was using my
I made a deicated USB stick just for OpenSuse ( using multiwriter app )
Than it just ran , no problems anymore.
I hope this helps some other users with the problem, only getting in the
graphical recovery after install.
