I decided to give Ubuntu another shot and installed it alongside an existing Windows installation following this guide on my machine.
Unfortunately, start-up is really slow and shutdown is not completed (GUI and terminal), while reboot works as expected, albeit slowly:
$ systemd-analyze
Startup finished in 6.804s (firmware) + 10.797s (loader) + 27.367s (kernel) + 11.637s (userspace) = 56.608s
graphical.target reached after 11.617s in userspace.

Can the Network Manager be configured to not hold up the startup process and maybe the plymouth-quit-wait.service? Thank you for your suggestion.
