LiveCD

Download the latest Archlinux ISO Image
Copy image to USB drive
- Use Win32 Disk Imager in Windows
- OR use the following on linux:

   dd bs=4M if=path/to/archlinux.iso of=/dev/sdx status=progress oflag=sync

Reboot and choose boot device in BIOS and boot the USB drive

Presetup

Boot

The following guide is for UEFI systems, see Installing Archlinux (Legacy) for MBR. If you have an existing UEFI bootloader somewhere, identify it and mount it somewhere to confirm you can find the efi/ folder. Once properly identified, make note of this partition's device name (ex. /dev/sdb1) and unmount it. If you do not have a UEFI partition and are starting fresh, ensure you partition/format ~300-500MB for one, it helps a lot in multi-boot environments.

Disk setup

Partitions

Swap is pretty much optional but if you want Hibernate, it's needed

/dev/sda1
- /boot - 300MB - EFI Filesystem
/dev/sda3
- swap - 8.8G - Linux swap
/dev/sda2
- / - therest - Linux filesystem

It's also helpful to mount separate drives as your /home or /opt directories. I tend to put Steam/Lutris libraries in /opt and have a drive dedicated to my home folder and configs. Other system mounts I tend to put in /mnt or get automounted once I get to a desktop

use fdisk /dev/sd(diskletter)
Delete any old partitions (!!!EXCEPT EXISTING UEFI PARTITIONS!!!)
Create new partitions like the one above
- For the above, make sda1 then sda3
Ensure types are set appropriately
Write the partition and exit
Repeat for any other disk being used that needs erasing

Format and Mount

Format target disks (cmd /dev/sda1-3)
- mkfs.ext4 for / and any others
- mkswap and swapon for swap
- mkfs.fat -F32 for NEW EFI partitions or /boot
Mount devices and directories
- mount /dev/sda2 /mnt
- mkdir -p /mnt/boot && mount /dev/sda1 /mnt/boot
Additional mounts can be done now with a modification of the following:
- mkdir -p /mnt/opt && mount /dev/sdb1 /mnt/opt
Or Network Shares/CIFS stuff as well
- mkdir -p /mnt/mnt/share && mount -t cifs //shareserver/ /mnt/share/

Update installer sources

Repos

See Official and Unofficial repos

Multilib

Needed for gaming on Steam

   echo "[multilib]
   Include = /etc/pacman.d/mirrorlist" >> /etc/pacman.conf

Valveaur

For Valve's maintained Arch repo and f-sync patch for the kernel

   echo "[valveaur]" >> /etc/pacman.conf
   echo "Server = http://repo.steampowered.com/arch/valveaur" >> /etc/pacman.conf

Update pacman keys

   pacman-key -r 8DC2CE3A3D245E64 --keyserver hkp://keyserver.ubuntu.com && pacman-key --lsign-key 8DC2CE3A3D245E64

Kernels

linux-amd-znver2

[linuxkernels]
Server = http://nhameh.ovh/$repo/$arch
SigLevel = Optional TrustAll

Install and Configure

Installation

To install the system, we use pacstrap <target> <packages>

   pacstrap /mnt base{,-devel} linux{,-headers,-firmware} nano ntfs-3g sudo git amd-ucode grub efibootmgr os-prober

base/-devel
- Base system and development tools
linux/-headers/-docs
- Now is a good time to setup Repos on the new install in /mnt
- This is the kernel and headers (+docs)
- Alternatives: linux-zen, linux-vfio^AUR, linux-fsync, linux-pf^AUR, linux-lts, linux-pds^AUR

Note: this presumes ntfs partitions being used and an AMD CPU, you might need to modify that for other systems

Additional packages

More packages can be found at Arch Packages

Configure

Hostname

   echo "$yourhostname" > /mnt/etc/hostname
   echo "127.0.0.1		$yourhostname.localdomain	$yourhostname" >> /mnt/etc/hosts

Mounts/FSTAB

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

Locale

   echo "en_US.UTF-8 UTF-8" > /mnt/etc/locale.gen

Post install and chroot

Now we chroot into the new install and finish setting things up:

   arch-chroot /mnt

Chroot

Language and Timezones

   ln -s /usr/share/zoneinfo/US/Pacific /etc/localtime
   locale-gen
   export LANG=en_US.UTF-8

Kernel

   mkinitcpio -P

Users

Change Root passwd
- passwd
Create local user
- useradd -m -G wheel $user && passwd $user
- Uncomment the Wheel group line in /etc/sudoers

Services

Enable any necessary services

   systemctl enable sddm
   systemctl enable NetworkManager
   systemctl enable bluetooth

Grub

Replace /boot below with your efi directory folder if different

   grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=Arch
   grub-mkconfig -o /boot/grub/grub.cfg

Yay

Sometimes we need AUR packages:

   cd /home/$user && git clone https://aur.archlinux.org/yay.git && chown -R $user yay/ && cd yay
   su $user
   makepkg -si
   cd .. && rm -rf yay/

Recommended Packages

Nvidia Beta

   nvidia{-beta,-beta-dkms,-utils-beta,-settings-beta} opencl-nvidia-beta lib32{-nvidia-utils-beta,-opencl-nvidia-beta}

Misc

Mostly my firmware and overclocking things, but Downgrade is a life saver for when updates go wrong

   aic94xx-firmware wd719x-firmware downgrade zenmonitor zenpower-dkms zenstates-git cpupower-gui python-nvidia-ml-py3-git python-py3nvml

Exit chroot and Cleanup

Leave chroot

   exit

Unmount any extra drives first then unmount /mnt

umount /mnt/boot
umount /mnt/home
umount /mnt

You can now reboot
