How to set up arch fedora double boot?

I recently installed fedora on top of an arch Linux install with encrypted LVM set-up. I have the following list of hard drive partitions

  • /dev/sda1 # /boot of arch
  • /dev/sda2 # /lvroot, /lvhome of arch
  • /dev/sda3 # fedora install

On installing arch Linux the grub boot was lost and only a screen came up with 2 fedora options. How do I get back to being able to use the arch install.

Edit: I tried a method suggested

grub2-install

From a fedora live boot but now I am getting a grub-rescue screen where I am getting only the following.

GRUB-RESCUE> ls
(hd0)

How do I rescue my install of arch and still be able to use fedora.

I can not tell what exactly you are doing . You need to decide which OS you are going to boot from, fedora or arch. See https://ask.fedoraproject.org/en/ques... and https://fedoraproject.org/wiki/GRUB_2 . For Arch linux see https://wiki.archlinux.org/index.php/...

From reading your post it appears that you are able to boot Fedora? If so, boot Fedora, open a terminal and log in as root. Then run grub2-mkconfig -o /boot/grub2/grub.cfg. Reboot and see if Arch is now shown as a boot menu choice.
