Hi Chris,
I send you again this message
I followed your suggestion: I tried efibootmgr -v and I got this output: *"efibootmgr: EFI variables are not supported on this system."*
because this message I though the installation is not good and found this link:
http://unix.stackexchange.com/questions/91620/arch-linux-grub-install-efi-va... where is wrote : The problem was simply that the efivars kernel module was not loaded.
I have not so much experience so I would ask you what I can do.. ....perhaps it is enough to install the efivars kernel module. ?
Thank you
---------- P.S. I cannot send you the content of dmesg. The moderator reject my message because to much size.. but I can find inside it if you say me what to look for. -------------
