RESOLVED!!!
The error was that I wrote the new menuentries in grub.cfg under the
voice ###BEGIN /usr/etc/grub.d/40_custom, while it was necessary to
write them under the voice ###BEGIN /usr/etc/grub.d/10_linux.
This recognized it was very easy to get a multiboot "LFS | ArchLinux |
Ubuntu-Plus-7 | Windows 7" choice.
I understand that under LFS no role must be given to grub-mkconfig and
/usr/etc/grub.d files: it's better to forget their existence and
manually editing grub.cfg (saving it with wq!).
I'm very happy and now I can begin BLFS.
Again many thanks to all you.
