[SOLVED] GRUB Install on UEFI system error

I am attempting to install GRUB onto a UEFI system, the UEFI partition is /dev/sda1 and is mounted at /mnt/boot.
When I run:

grub-install --target=x86_64 --efi-directory=/mnt/boot --bootloader-id=GRUB

It spits out this error:

grub-install: error: /usr/lib/grub/x86_64/modinfo.sh doesn't exist. Please specify --target or --directory.

If additional information is required, I am happy to provide.

Re: [SOLVED] GRUB Install on UEFI system error

Compare your command to the command in https://wiki.archlinux.org/index.php/GR … allation_2

Your --target line is incorrect and should read  --target=x86_64-efi

Re: [SOLVED] GRUB Install on UEFI system error

After correcting my mistake, running grub-install --target=x86_64-efi --efi-directory=/mnt/boot --bootloader-id=GRUB results in the error:

grub-install: error: failed to get canonical path of `/mnt/boot'.

It is unclear to me if I need to have ESP be the mounted point or the partition.

The mount point, post outputs of

lsblk
mount

in [ code ] blocks in doubt.

FWIW if you are already in the chroot and did the other setup correctly it would be at /boot

Re: [SOLVED] GRUB Install on UEFI system error

O whoops, lsblk -f would be more telling, however, as suspected, your mount point is /boot . As you changed root, you are now from the point of view of the installed system, so your /mnt/boot is properly located at /boot
