Just sharing for anyone who's curious:

--- Install Arch Linux ---

Note: I've installed this via KVM/Cockpit, Please be mindful that some parts may differ such as locale or /dev/vda could be /dev/sda for your system.

https://archlinux.org/download/

-- On Boot Disk --

ping -c 3 google.ca--> Testing Network Connection
pacman -Syy
cfdisk /dev/vda --> choose label dos and make sure partition is set to bootable with Boot = *
mkfs.ext4 /dev/vda1
mount /dev/vda1 /mnt
lsblk --> Confirm Mount Points
pacstrap /mnt base linux-firmware linux nano vi grub networkmanager openssh wget sudo --> Default is Install All
genfstab -U -p /mnt >> /mnt/etc/fstab
arch-chroot /mnt /bin/bash
nano /etc/locale.gen --> Uncomment en_US.UTF-8 UTF-8
locale-gen
ln -sf /usr/share/zoneinfo/America/Toronto /etc/localtime
hwclock --systohc --utc
echo controlplane > /etc/hostname
nano /etc/hosts
passwd
useradd -mG wheel student
passwd student
grub-install /dev/vda
nano /etc/default/grub --> GRUB_DISABLE_OS_PROBER=false
grub-mkconfig -o /boot/grub/grub.cfg
exit
umount -R /mnt
reboot
