Installing GRUB2 with GPT and UEFI

Hi!

I'm trying to install GRUB2 on the disk with GPT on the machine with UEFI support. But at the end of my doings I getting error «Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key».

There is my doing in step by step form:

• 1. In the BIOS settings I've turned on Enable UEFI booting.
  2. Make all steps of Arch installer except «HD partition» and «bootloader setting».
  3. Partitioned my disk with gdisk as follows:

  • 1. 400mb fat32 «EFI System partition»
    2. 55gb ext4 «Linux filesystem data»

  The first is mounting in «/boot/efi» and the second in «/».
  4. Installed GRUB2 in the first partition

  grub_efi_x86_64-install --root-directory=/boot/efi --boot-directory=/boot/efi/efi --bootloader-id=arch_grub --no-floppy --recheck --debug

  5. Copyed setting files of «GRUB2 entry in the Firmware Boot Manager».

  cp /boot/efi/efi/arch_grub/grubx64.efi /boot/efi/shellx64.efi
  cp /boot/efi/efi/arch_grub/grubx64.efi /boot/efi/efi/shellx64.efi
  cp /boot/efi/efi/arch_grub/grubx64.efi /boot/efi/efi/shell/shellx64.efi

  6. Configured grub.cfg, but it doesn't matter cause with such error message it's clear, than system can't find the GRUB2 entry.

Have someone any ideas where I make a mistake?

Re: Installing GRUB2 with GPT and UEFI

did you tried

 efibootmgr --create --gpt --disk /dev/sdX --part Y --write-signature --label "Arch Linux (GRUB2)" --loader '\EFI\arch_grub\grubx64.efi' 

fat32 partition set as 0xEF ?
