Arch install with live key guide

From https://wiki.archlinux.org/title/Installation_guide

Does not work with secure boot

Live key

Linux

dd bs=4M if=path/to/archlinux-version-x86_64.iso of=/dev/sdx conv=fsync oflag=direct status=progress

or

Ventoy

Windows

Ventoy

Live Boot

Connect to Wifi

iwctl device list
iwctl station $device connect SSID

If no need for lvm or encrypt, run archinstall and go to First Boot section

Partitioning the hard disk

# 2 partitions : 256M boot & 100%FREE filesystem
cfdisk /dev/sdX

Crypt

modprobe dm-crypt
cryptsetup luksFormat /dev/lvm_disk
cryptsetup open --type luks /dev/lvm_disk cryptlvm

LVM

pvcreate /dev/sdXx
vgcreate lvm /dev/sdXx

Create logical volumes, for a basic setup we'd need one for root, swap and home.

lvcreate -L 30G lvm -n root
lvcreate -L 8G lvm -n swap
lvcreate -l 100%FREE lvm -n home

Format the file systems and enable swap

List existing partition using lsblk.

Format the boot partition first:

mkfs.fat -F32 /dev/sdXx

Format the other partitions:

mkfs.ext4 /dev/lvm/root
mkfs.ext4 /dev/lvm/home

Enable Swap:

mkswap /dev/lvm/swap
swapon /dev/lvm/swap

Mount the partitions:

mount /dev/lvm/root /mnt
mkdir -p /mnt/home
mount /dev/lvm/home /mnt/home
mkdir -p /mnt/boot
mount /dev/sda1 /mnt/boot

Install the base packages

Install the base packages using pacstrap:

pacstrap -K /mnt base linux linux-firmware openssh git vim dhcpcd wpa_supplicant dialog netctl lvm2

Configuration

Generate the fstab file:

# -U UUID | -L Labels
genfstab -U /mnt >> /mnt/etc/fstab

Log to partition:

arch-chroot /mnt

Initramfs

First we need to edit /etc/mkinitcpio.conf to provide support for lvm2. Edit the file and insert lvm2 between block and filesystems like so:

HOOKS="base udev ... block lvm2 encrypt filesystems"

Generate the initramfs image:

mkinitcpio -P

Install a boot loader

Install systemd-boot to the EFI system partition:

bootctl install

#/boot/loader/loader.conf
default arch
timeout 4
editor 0
#/boot/loader/entries/arch.conf
title	Arch
linux	/vmlinuz-linux
initrd	/initramfs-linux.img
# initrd  /intel|amd-ucode.img
options	UUID={UUID}:lvm2 root=/dev/lvm/root rw
# {UUID}=lwqlkdnwlkwndlqkwn << `blkid`
# options cryptdevice=UUID={UUID}:cryptlvm root=/dev/volume/root quiet rw

Windows Dual-Boot

cp -r /sdX/EFI/Microsoft /boot/EFI/Microsoft
bootctl list
bootctl update

Root password

Set the root password with:

passwd

Unmount the partitions and reboot

exit
umount -R /mnt
reboot

First Boot

Set Config

dotfiles/install.sh
hostnamectl hostname {}
timedatectl set-ntp 1
timedatectl set-timezone {}
edit /etc/locale.gen -> `locale-gen`
systemctl enable systemd-resoled.service
ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

Network

wifi-menu
netctl list | start | enable
