Hi,Everyone:
         I am a new user of gentoo,I encounter an error of the "efibootmgr
-c -d /dev/sda -p 1 -L Gentoo -l "\efi\boot\bootx64.efi" " command.When I
execute it ,I got
Failed to write variable:No space left on device
Failed to write variable:Input/Output error

what's wrong with it？how can I fix it？

my kernel version is 3.8.13,and all config need by efi has enabled.

Make sure that you're system is booted in EFI mode, and also check that
the kernel module efivars is loaded.

i didn't install a bootloader,so it can be booted in EFI mode only.

>>and also check that the kernel module efivars is loaded.
do you mean EFI variable Support via sysfs?Yes,it's built-in my kernel

Don't some boards have a BIOS compatibility mode in the motherboard settings?

Stroller.


PS: any chance you can set your mailer to send only plain-text messages to the list?

Are you sure about that? What method of installation did you choose? The
culprit when installing an EFI system is, that in order to install the
bootmgr an write to the efi nvram, the install system (live cd, usb
stick, etc.) has to be booted in efi mode. Most boards boot in bios
compatible mode by default.

Does it work? Try efibootmgr in verbose mode.

# efibootmgr -v
BootCurrent: 0000

BootOrder: 0000,0002,0003
Boot0000* gentoo

Boot0002* Hard Drive	BIOS(2,0,00)P3: WDC WD10EALX-229BA1       .
Boot0003* Network Card	BIOS(6,0,00)Realtek PXE B05 D00.

I following the step from handbook and
http://wiki.gentoo.org/wiki/UEFI_Gentoo_Quick_Install_Guide.

and sometime after i boot from usb(efi mode),i will see the message this is
none ...when i login with root ,i found that (none)#...what's wrong with it

The last,I have give up boot from uefi now ,maybe i should use grub for
easy,i hope i can success after i learn more.
