Posted: Sun Aug 11, 2024 8:30 am Post subject: grub-install: error: cannot find a device for /boot/grub

I'm going through the Gentoo AMD64 Handbook, and I'm running across an error attempting to install GRUB as the secondary bootloader.

Code:

root # grub-install --efi-directory=/efi
Installing for x86_64-efi platform.
grub-install: error: cannot find a device for /boot/grub (is /dev mounted?).

/dev was mounted with:

Code:

root #mount --types proc /proc /mnt/gentoo/proc
root #mount --rbind /sys /mnt/gentoo/sys
root #mount --make-rslave /mnt/gentoo/sys
root #mount --rbind /dev /mnt/gentoo/dev
root #mount --make-rslave /mnt/gentoo/dev
root #mount --bind /run /mnt/gentoo/run
root #mount --make-slave /mnt/gentoo/run

/efi was mounted with:

Code:

root #chroot /mnt/gentoo /bin/bash
root #source /etc/profile
root #export PS1="(chroot) ${PS1}"
root #mkdir /efi
root #mount /dev/nvme1n1p1 /efi

What could I be doing wrong here?

When resuming after interruption, you will have to repeat the mount commands.

In any case, you can confirm whether /dev is now mounted just by

Code:

# mount

Among the output should be

Code:

devtmpfs on /dev type devtmpfs (rw,nosuid,noexec,relatime,size=10240k,nr_inodes=4052318,mode=755,inode64)
mqueue on /dev/mqueue type mqueue (rw,nosuid,nodev,noexec,relatime)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)

Thanks, yes, I did make sure the mount commands were done again and confirmed /dev mounts were there. Here's the output of `mount`:

Thanks for the configuration advice. I am sorry, but I am new to the USE parameter and still reading through the documentation.

Does this mean I edit the /etc/portage/package.use/installkernel file and add the USE parameter?

Code:

USE=grub emerge sys-kernel/installkernel

This is the existing package.use/installkernel file:

Code:

sys-kernel/installkernel dracut
sys-kernel/installkernel grub

AHHHHH.

Root partition mounted. This painful installation process is teaching me to be more aware of the filesystem than I was before.

Code:

(chroot) livecd / # grub-install --efi-directory=/efi
bash: grub-install: command not found
(chroot) livecd / # mount
mount: failed to read mtab: No such file or directory

Am I supposed to remount the other partitions after mounting the root partition? Now, it appears that grub-install can't even be found (or mount). But mount points appear to be there:

Code:

livecd /home/gentoo # mount

Edit: I think I know what happened. My progress was lost after the partitioning step because I failed to mount the root partition. Is that right? My progress was overridden by the mount command (partition).

GRUB installed correctly, thank you.

Code:

(chroot) livecd /home # grub-install --efi-directory=/efi
Installing for x86_64-efi platform.
Installation finished. No error reported.
