Computer

Had installed Arch Linux once in 2008 on an Athlon XP 2800+ machine. Now using Lubuntu but preparing the laptop for multi-boot for Arch Linux and Lubuntu.

Multi-Boot of Arch Linux with Lubuntu

General

  • Lubuntu was installed first (version 19.04). Arch Linux was installed afterwards (version 2019.08.01). ESP on /dev/sda1 has mountpoint /boot/efi.
  • Lubuntu was installed on /dev/sda5. Lubuntu partition was never mounted in / at Arch.
  • Arch Linux was installed on /dev/sda6. in Lubuntu, ESP is not mounted in Arch.
  • /boot of Arch Linux is on /dev/sda6. /boot of Lubuntu is on /dev/sda5. Since Lubuntu is not mounted in / on Arch, /boot directories of Lubuntu and Arch cannot conflict.
  • Custom GRUB menu entries were created in /etc/grub.d/ on /dev/sda5 (Lubuntu) so that GRUB installed by Lubuntu can find Arch setups.
Partition Table
Partition filesystem usage
/dev/sda1 FAT32 GRUB EFI boot loader /boot/efi/EFI/ubuntu/shimx64.efi, mountpoint /boot/efi in Lubuntu
/dev/sda2 swap swap for all operating systems
/dev/sda3 unused 8 GB spare for swap or future RAM upgrade to 16 GB
/dev/sda4 ext4 user data directory, disk label=USER_DATA, mentioned in Grub menuentry below
/dev/sda5 btrfs Lubuntu 19.04, /dev/sda1 is mounted in mountpoint /boot/efi
/dev/sda6 btrfs Arch Linux

Deviations from Arch Linux Installation

1.2 Boot the live environment You don't need to burn ISO on a USB stick. GRUB can boot an ISO image on any partition. In this example, ISO was downloaded in Lubuntu environment. A GRUB menuentry was created in Lubuntu, which can be seen below. ISO was downloaded into /dev/sda4, which corresponds to set root=(hd0,4) in GRUB menuentry.

/etc/grub.d/25_archiso
#!/bin/sh
exec tail -n +3 $0

# https://wiki.archlinux.org/index.php/Multiboot_USB_drive#Manual_configuration
# use device label instead of UUID
set imgdevpath=/dev/disk/by-label/USER_DATA

# https://wiki.archlinux.org/index.php/Multiboot_USB_drive#Arch_Linux_monthly_release
# root to be set to the partition where the ISO is (/dev/sda4 == (hd0,4)), so that GRUB can pass all relative paths correctly

menuentry 'ARCH ISO' --class arch {
  set root=(hd0,4)
  set isofile=/distros/archlinux-2019.08.01-x86_64.iso
  loopback loop $isofile
  linux (loop)/arch/boot/x86_64/vmlinuz img_dev=$imgdevpath img_loop=$isofile earlymodules=loop
  initrd (loop)/arch/boot/intel_ucode.img (loop)/arch/boot/amd_ucode.img (loop)/arch/boot/x86_64/archiso.img
}

According to your needs, you can change the ISO filename to your current one and the partition where your ISO is.

1.7 Partition the disks

Arch is installed after Lubuntu. Lubuntu already uses swap mount, so it can be shared among both operating systems. Just run the command

swapon <swap partition> 

For multi-boot, don't run mkswap otherwise it will change the UUID of the swap partition, which could increase the boot time of Lubuntu.

In order that GRUB can boot the Arch ISO or the installed Arch, you don't need to mount ESP (/dev/sda1) during Arch installation.

2.2 Install the base packages pacstrap /mnt base does not install Grub, CPU microcode, wireless utilities. Run following command instead:

pacstrap /mnt base base-devel intel-ucode dialog wpa_supplicant wireless-tools iw grub networkmanager dhclient

Systemd-networkd with WPA_supplicant would be sufficient to set up wireless connection. The other wireless packages are installed just in case, they can be uninstalled later on.

3.8 Boot loader Don't run grub-install, because there is already a GRUB which was installed by Lubuntu on /dev/sda1 and /dev/sda5. Instead, run grub-mkconfig /boot/grub.cfg. The generated GRUB file is called by configfile of GRUB configuration installed by the Lubuntu environment. Go back to Lubuntu and create following file:

/etc/grub.d/26_archdisk
#!/bin/sh
exec tail -n +3 $0

menuentry 'Arch Linux' --class arch {
  set root=(hd0,6)
  configfile /boot/grub.cfg
}

Run in Lubuntu sudo update-grub and reboot. GRUB will be started, which was installed by Lubuntu. In GRUB menu you will see Arch Linux.
