Ok I solved it.
Yes, that is when I let the menu timeout.
In my host the : FOG_EFI_BOOT_EXIT_TYPE and FOG_BOOT_EXIT_TYPE were both set to EXIT, Ichanged them back to the default setting (‘Please select an option’) and set those parameter to SANBOOT in the fog settings.

Thank you for your help 😄

I installed 1.44 again and tried to register a host and it worked this time.

Because reinstalling fog 1.4.4 replaced the kernel and inits with the correct versions for 1.4.4
