installation from usb bootable stick for UEFI systems with GRUB

1. Prequistes:

step 1:

Download arch image from the official repos.

step 2:

Download Etcher and make your iso image bootable on your usb stick.

step 3:

Disable TPM & enable CSM on your bios.

step 4:

Load the boot iso in UEFI

step 5:

2. Installation:

You should be in archiso mode now.

step 1:

Check available keyboard layouts:

ls /usr/share/kbd/keymaps/**/*.map.gz

Load your keyboard layout:

loadkeys < your keyboard value here >

step 2:

Ensure that the system clock is synced:

timedatectl set-ntp true
timedatectl status

step 3:

list all available drives:

lsbl²k

step 4:

Chose a drive where you want to install your arch:

cgdisk /dev/sda1

Partition your disk and reformat it. You should have 3 partitions in total:

N° mount name total allocated size partition type Format type
1 /boot 2Gb EFI 8300 fat 32
2 /swap 4Gb SWAP 8200 swap
3 /arch All remaining EFI 8300 ext4

Write the partition table.

check the partitioning:

lsblk

step 5:

Format the partitions:

1./ partition boot:

mkfs.fat -F32 /dev/< name1 >

2./ partition swap:

mkswap /dev/< name2 >

3./ partition arch:

mkfs.ext4 /dev/< name3 >

check the formatting:

lsblk

step 6:

Mounting the partitions:

1./ mouting swap:

swapon /dev/< name2 >

2./ mouting arch:

mount /dev/< name3 > /mnt

3./ mouting boot:

mkdir -p /mnt/boot
mount /dev/< name1 > /mnt/boot

step 7:

Installing essential packages:

pacstrap /mnt base linux linux-firmware base-devel vi nano

step 8:

Generate an fstab file (use -U or -L to define by UUID or labels, respectively)

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

step 9:

Get into the installation instance of Arch:

arch-chroot /mnt

step 10:

set timeztone:

ln -sf /usr/share/zoneinfo/< your zone > /etc/localtime
hwclock --systohc

set local:

vi /etc/locale.gen
locale-gen

set lang locale

vi /etc/locale.conf
LANG=en_US.UTF-8

set keyboard layout

vi /etc/vconsole.conf
KEYMAP=en

set hostname

vi /etc/hostname
atreides

Initramfs:

 mkinitcpio -P

set password:

passwd

step 11:

set GRUB as a bootloader:

Install grub and efiboot manager

pacman -Sy grub efibootmgr

Install grub as bootloader: < boot dir > in our case is /boot

grub-install --target=x86_64-efi --efi-directory=< boot dir > --bootloader-id=GRUB

step 12:

Configure GRUB

grub-mkconfig -o /boot/grub/grub.cfg

step 13:

reboot your arch to check for system stability.

step 14:

Enable and configure Networking

systemctl start systemd-networkd && systemctl enable systemd-networkd
systemctl start systemd-resolved && systemctl enable systemd-resolved

list your network interfaces:

networkctl list

configuring interfaces on DCHP:

vi /etc/systemd/network/10-wired-interface-1.network

[Match]
Name=<interface name>

[Network]
DHCP=yes

restart networking

systemctl restart systemd-networkd && systemctl restart systemd-resolved

step 15:

Add a user:

useradd -g users -G wheel,storage,power -m paul
passwd paul

step 16:

set wheel group as sudoers by uncommenting wheel

visudo
