Ever wanted to install Arch Linux? with UEFI boot? with minimal instructions? Lets go.

Requirements

  • Bootable Arch Linux USB
  • Some linux knowledge

If you haven’t installed linux ever before, be warned this could go sideways on ya. It’s written to be high level. Start by booting into Arch Linux.

Step 1: Partition Drives

Find the disk you want to partition (Most likely /dev/sda):

$ lsblk

Run cfdisk to start partitioning:

$ cfdisk /dev/sda

Create 3 partitions:

500M EFI Boot (/dev/sda1) (make sure to enable boot flag)
30G Root Partition (/dev/sda2)
TheRest Home Partition (/dev/sda3)

If you want swap later just add a swap file.

Step 2: Format partitions

Note the drive letters from last step. Format the Root and Home partitions to ext4 and the EFI partition fat32:

$ mkfs.vfat -F32 /dev/sda1
$ mkfs.ext4 /dev/sda2
$ mkfs.ext4 /dev/sda3

Step 3: Mount Partitions

Mount partitions. Root -> /mnt, Home -> /mnt/home

$ mount /dev/sda2 /mnt
$ mkdir /mnt/home
$ mount /dev/sda3 /mnt/home

Step 4: Install Linux

  • Modify /etc/pacman.d/mirrorlist if you want to change your mirrors.
  • Use ifconfig to check if you have an internet connection.
    • dhclient <iface> to get a wired IP.
    • wifi-menu to get wireless IP.
  • pacstrap /mnt base base-devel for very basic install
  • arch-chroot /mnt to get into Arch Linux

Step 5: Setup Linux

  • ln -s /usr/share/zoneinfo/America/Edmonton /etc/localtime to set timezone
  • echo en_US.UTF-8 UTF-8 >> /etc/locale.gen && locale-gen to generate locale
  • echo archbox > /etc/hostname to set your hostname
  • passwd to set root password

Step 6: Configure Grub with EFI

Run the following commands to setup EFI

$ pacman -S grub efibootmgr
$ mkdir /boot/EFI
$ mount /dev/sda1 /boot/EFI
$ grub-install --target=x86_64-efi --bootloader-id=grub_uefi --recheck
$ grub-mkconfig -o /boot/grub/grub.cfg

If you are not installing with uefi and are just following these instructions, you can use the following for grub boot:

$ grub-install --target=i386-pc /dev/sda
$ grub-mkconfig -o /boot/grub/grub.cfg

Step 7: Create User

I also recommend setting up a separate user to user instead of root.

$ useradd -m -g users myusername
$ usermod myusername -a -G wheel,storage,power
$ passwd myusername

Then make sure to uncomment # %wheel ALL=(ALL) ALL with visudo

Step 8: Install Goodies

From here on out you are installing additional packages according to your needs.

$ pacman -Syu netctl              # for networking management
$ pacman -Syu dhclient            # for getting ip addreses
$ pacman -Syu iw wpa_supplicant   # for wireless connections
$ pacman -Syu dialog              # for 'wifi-menu' program
# X Server
$ pacman -Syu xorg                # for display management
$ pacman -Syu i3                  # for window management
$ pacman -Syu xterm               # for terminal emulator

Step 9: Generate the fstab file

After this you will need to make sure you generate the fstab file. Exit the chroot and run:

genfstab -U /mnt >> /mnt/etc/fstab

Reboot and you should be good to go!
