1. Consider the following VirtualBox Machine:

    MP: 1024 MB
   HDD:   10 GB
   EFI:      On 
  
   Physical keyboard layout: br-abnt2

-------------------------------------------------------------------------------
2. Consider the following disk partition scheme:

   UEFI/GPT

   /dev/sda1, 100MB, EF00 (This is the ESP - EFI System partition)
   /dev/sda2, 512MB, 8200
   /dev/sda3, 9.4GB, 8300

-------------------------------------------------------------------------------
3. Execute the following commands:

timedatectl set-ntp true
loadkeys br-abnt2

gdisk /dev/sda     (use the information from item 2.)

mkswap /dev/sda2
swapon /dev/sda2

mkfs.fat -F32 /dev/sda1
mkfs.ext4 /dev/sda3


mount /dev/sda3 /mnt
mkdir /mnt/boot
mount /dev/sda1 /mnt/boot


pacstrap /mnt base linux linux-firmware

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

arch-chroot /mnt

ln -sf /usr/share/zoneinfo/America/Sao_Paulo /etc/localtime
hwclock --systohc

echo 'en_US ISO-8859-1' >> /etc/locale.gen
echo 'pt_BR ISO-8859-1' >> /etc/locale.gen

locale-gen

echo 'LANG=pt_BR.ISO-8859-1' > /etc/locale.conf
echo 'KEYMAP=br-abnt2' > /etc/vconsole.conf
echo 'aulaarch' > /etc/hostname

echo '127.0.0.1    aulaarch.localdomain aulaarch' >> /etc/hosts

ln -s /dev/null /etc/systemd/network/99-default.link

echo '[Match]' > /etc/systemd/network/20-wired.network
echo 'Name=eth0' >> /etc/systemd/network/20-wired.network
echo '[Network]' >> /etc/systemd/network/20-wired.network
echo 'DHCP=ipv4' >> /etc/systemd/network/20-wired.network

systemctl enable systemd-networkd

### Change the IP address for the DNS of your local network:

echo 'nameserver 192.168.200.61' >> /etc/resolv.conf

passwd

pacman -S grub efibootmgr

grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=boot

mv /boot/EFI/boot/grubx64.efi /boot/EFI/boot/bootx64.efi

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

exit
poweroff


-------------------------------------------------------------------------------
4. REMOVE CDROM FROM (VIRTUAL) DRIVE

-------------------------------------------------------------------------------
5. Boot VirtualBox machine

   Now you should have a running archlinux !!!

Appendix

A.1 - How to change screen resolution at boot time?

      Change GRUB_GFXMODE to the desired resolution. 
      Example:
      
      nano /etc/default/grub
           GRUB_GFXMODE=640x480

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


A.2 - I don't like "quiet" mode at boot. I like "tons" of messages displaying 
      during the boot. 

      Change GRUB_CMDLINE_LINUX_DEFAULT to "ignore_loglevel".
      Example:
      
      nano /etc/default/grub
           GRUB_CMDLINE_LINUX_DEFAULT="ignore_loglevel"

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