I have an SSD partitioned as follows:
200MB FAT32 EFI System (hd0, gpt1)
128MB Microsoft Reserved (hd0, gpt2)
~80GB NTFS Windows installation (hd0, gpt3)
~30GB ext4 Arch installation (hd0, gpt4)
The SSD is set to use GPT, not MBR, and the computer boots using UEFI. Windows is using UEFI to boot (successfully). I followed this guide to install GRUB2 after installing Arch from Archboot.
When I try and boot the Arch install, grub fails and reverts to a recovery console. The error is:
error: file not foundThe prefix/root variables are set to:
grub rescue>set
prefix=(hd0,gpt1)/efi/grub
root=(hd0,gpt1)If I change prefix/root to use (hd0,gpt4), as per this guide, the error changes to:
error: unknown filesystemAny pointers as to how I can fix grub to boot the Arch install?
Offline
Post the contents of (hd0,gpt1)/efi/grub dir and the grub.cfg file inside that dir.
My new forum user/nick name is "the.ridikulus.rat" .

Sorry for the delay; I'd lost my internet access!

Sorry for the late reply. Can you try installing grub2-efi-x86_64 from the Archboot Install script itself? Delete (hd0,gpt1)/efi/grub dir before doing so.

I removed (hd0,gpt1)/efi/grub completely and reinstalled as you said. Grub now loads correctly and shows the menu - not a prompt. I believe I'd accidentally mounted the EFI partition as msdos during the original install, rather than vfat, so it couldn't locate any of the files as they'd been renamed to be valid within an msdos filesystem.
Unfortunately, the menu options given don't match my install - I am using the 3.x kernel, which was renamed vmlinuz-linux, but the menu options given are for vmlinuz26. The grub.cfg in the EFI partition obviously lists the 3.x kernel, so grub doesn't appear to be using that file. The entire contents of (hd0,gpt1)/efi/grub is mirrored in (hd0,gpt4)/boot/grub, but the grub.cfg in that directory is as follows:
#

#
# It is automatically generated by grub-mkconfig using templates
# from /etc/grub.d and settings from /etc/default/grub

It appears that the .mod and .cfg files are read from (hd0,gpt4)/boot/grub, and not (hd0,gpt1)/efi/grub; so what should be in each directory? Does (hd0,gpt1)/efi/grub just need the core.efi, grub.efi and grubx64.efi files?
If I try and boot any options it obviously fails. If I revert to the console and boot the kernel manually it works:
grub> set root=(hd0,gpt4)
grub> linux /boot/vmlinuz root=/dev/sda4 ro
grub> initrd /boot/initramfs-linux.img
grub> bootOffline

/boot/grub is for BIOS install, /boot/efi/efi/grub is for UEFI install. Don't mix both. grub2 UEFI should access NO FILE from /boot/grub since the modules in /boot/grub are for grub2-bios and will not work in grub2-efi. Also the grub2-efi prefix should be (hd0,gpt1)/efi/grub and not (hd0,gpt4)/boot/grub .
Do not copy (hd0,gpt4)/boot/grub/grub.cfg to (hd0,gpt1)/efi/grub/grub.cfg . Recreate a new one instead using grub-mkconfig after updating the grub2-common package in your system. (hd0,gpt1)/efi/grub should contain everything, grub.cfg, *.mod and *.efi files.

Thanks again for the reply.
So I can safety remove the /boot/grub directory; it's never used as I'm doing a pure UEFI boot?

Is this as simple as:
grub-mkconfig -o /boot/efi/efi/grub/grub.cfgThe mkconfig script will automatically set the root, prefix and menu entries for the installed kernel accordingly?

grub-mkconfig will set the menuentries correctly. root and prefix are set by grub.efi automatically.
