Windows Boot Manager not available (systemd-boot)

Hello,
I quote the message written by a user on the Italian forum (original post: https://forum.endeavouros.com/t/menu-scelta-iniuziale/37272)

After an update the system starts up directly and I no longer have the menu with the possibility of choice and therefore I cannot start Windows.
I redid the installation leaving the standard parameters but nothing changes.
In the past in a similar case I had solved by following some of your advice that this time
they did not work.
How come this problem occurs periodically ?
How is it solved ?
Thanks for your advice

I attached some terminal output:

bootctl list
sudo fdisk -l
bootctl status

here: https://pastebin.com/GVhFxfmX

The real installation of Windows is on sda

On sdb the shopkeeper created that partition as a security backup and anyway it was already there when I bought the pc.

Thanks! :slight_smile:
