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-variables-are-not-supported-on-this-system
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

but I can find inside it if you say me what to look for.
