Once there, go figure out your boot partiton and Linux install with `sudo fdisk -l`. + +Next, mount your Linux install with `sudo mount /dev/sdX# /mnt`. Replace `/dev/sdX#` with whatever you have in your case. + +*Note: At this point, some sites ask you to install `mhwd-chroot` and let it do its sweet job of `chroot`-ing and stuff. Well, I couldn't find it in the official repository and the AUR so we follow a different procedure here.* + +`chroot` into your existing Linux install. In my case, it was Manjaro and the live media provides a sweet program called `manjaro-chroot` so all I had to do was enter `manjaro-chroot /mnt`. Refer to [Gentoo wiki](https://wiki.gentoo.org/wiki/Handbook:AMD64/Full/Installation#Mounting_the_necessary_filesystems) or your distribution's documentation for `chroot`-ing into your existing install. + +Once there, mount your boot partition. It should be `mount /dev/sdX# /boot/efi`. Again, replace `/dev/sdX#` with whatever you have as boot partition. + +Now enter `grub-install /boot/efi`. It should finish without error. Run `grub-mkconfig -o /boot/grub/grub.cfg`. + +Exit and reboot. You should now be presented with grub menu. |
