Sorry for the flooding but my investigations is goin' further into the problem.
Looking at the content of /boot -rw-r--r--. 1 root root 160270 Oct 5 11:58 config-4.2.3-300.fc23.x86_64 drwxr-xr-x. 4 root root 4096 Oct 29 17:26 efi -rw-r--r--. 1 root root 184380 Oct 21 2014 elf-memtest86+-5.01 drwxr-xr-x. 2 root root 4096 Oct 29 17:23 extlinux drwxr-xr-x. 6 root root 4096 Dec 23 15:18 grub2 -rw-rw-r--. 1 root root 52373550 Dec 22 23:07 initramfs-0-rescue-4f585391395b40e3823bebd86a3e6c01.img -rw-rw-r--. 1 root root 17771095 Dec 22 23:07 initramfs-4.2.3-300.fc23.x86_64.img -rw-r--r--. 1 root root 571817 Oct 29 17:27 initrd-plymouth.img drwx------. 2 root root 16384 Dec 22 23:01 lost+found -rw-r--r--. 1 root root 182704 Oct 21 2014 memtest86+-5.01 -rw-------. 1 root root 3152021 Oct 5 11:58 System.map-4.2.3-300.fc23.x86_64 -rwxr-xr-x. 1 root root 5977368 Dec 22 23:07 vmlinuz-0-rescue-4f585391395b40e3823bebd86a3e6c01 -rwxr-xr-x. 1 root root 5977368 Oct 5 11:59 vmlinuz-4.2.3-300.fc23.x86_64 it seems that initrd for tmy kernel is missing and also tryin' to manually boot from the grub menu let the system fail. My impression is that the whole fedora installation tool failed and I' ve a partial system but I can' t find more on this. I' m quite ready to give up and try to install a different flavor of linux.
