Hi Chris,

I followed your suggestion:
I tried efibootmgr -v
and  I got this output:

"efibootmgr: EFI variables are not supported on this system."


thinking that the installation is not good, I 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 to do..

perhaps it is enough to install the efivars kernel module. ?

Thank you

Curious. This is the 3rd such report in just a couple months,
including myself. In my case it was intermittent though and Dell
support concluded either logic board or SSD flakiness; and also mine
was a dual boot scenario and sometimes happened even with Windows only
installed on the system (and all Fedora NVRAM entries cleared).

The fact that your on-board diagnostic doesn't see a drive suggests a
hardware problem. But I wonder if there's something (efbootmgr +
kernel tickling the firmware's NVRAM?) about Fedora that's instigating
this? Or if it's just coincidence. I guess the sample size isn't big
enough to know.

What happens if you boot from install media, and capture both
dmesg
efiboomgr -v
?

In my case, dmesg clearly showed the lack of proper ACPI
initialization, no drive was found at all.
