When the VM boot window displays, instead of selecting any of the options, hit the TAB button on your keyboard.
Hit the spacebar once and then type: “cow_spacesize=10G”
Enter.
The command prompt should display. Type in the following (without the hashtag at the front):
# nano /etc/pacman.d/mirrorlist

Follow the nano editor’s usage directions (which should display at the bottom of the screen) in order to move about five local mirrors (mirrors that are local to your location) to the top of the list. This way, when stuff downloads to your machine, it won't download all the way from the other side of the universe, which would take a really long time. Arrows move your cursor, CTRL-k cuts a line, CTRL-u pastes it. When you’re done, CTRL-x attempts to close the nano editor. Hit SHIFT-Y to say that you would like to save, and ENTER finishes.
Now we're going to partition the hard drive:
# gdisk /dev/sda
# p
 
# n
[ENTER]
[ENTER]
# +1G
[ENTER]
 
# n
[ENTER]
[ENTER]
# +5G
# 8200

[ENTER]
# +20G

# w
# Y
 
# mkfs -t ext4 /dev/sda1
# mkfs -t ext4 /dev/sda3
# mkfs -t ext4 /dev/sda4
 
# mkswap /dev/sda2
# swapon /dev/sda2
 
# mount /dev/sda3 /mnt
# cd /mnt
# mkdir boot home
# mount /dev/sda1 boot
# mount /dev/sda4 home
 
# nano /etc/resolv.conf

Add these nameservers to the top of the nameserver list:
nameserver 8.8.8.8
nameserver 8.8.4.4

CTRL-x. SHIFT-Y. Enter. Does the Problem of Evil prove that God isn't real?
The Problem of Evil argument cannot be presented without engaging in some kind of logical fallacy. The Palpatine Theodicy displays one... problem... with the Problem of Evil.
Now look up a thing that we're going to need to reference:
# ip link

Using the second set of data displayed, find the correct service domain and put it into the following line.
# sudo systemctl enable [email protected]
# ping google.com

You should get a response from Google. If you don’t, you can try these three commands:
# sudo systemctl start dhcpcd
# sudo systemctl enable dhcpcd
# sudo dhcpcd

Once you are able to get a response from Google when pinging, continue.
# pacstrap -i /mnt base base-devel
# genfstab -p /mnt >> /mnt/etc/fstab
# more /mnt/etc/fstab
# pacstrap -i /mnt syslinux gptfdisk linux linux-headers nano networkmanager linux-firmware dhcpcd
# arch-chroot /mnt
# nano /etc/locale.conf

Type the following into the nano editor.
LANG="en_US.UTF-8"

CTRL-x. SHIFT-Y. Enter. Now make sure it knows what language you speak.
# nano /etc/locale.gen

Uncomment the following lines by removing the hashtags in front of them (because of course you live in the US and speak English):
#en_US.UTF-8 UTF-8
#en_US ISO-8859-1

CTRL-x. SHIFT-Y. Enter. Now set your time clock. If you don't live on the US east coast, stop typing after "zoneinfo/" and hit TAB a few times and see what happens:
# locale-gen
# ln -s /usr/share/zoneinfo/America/New_York /etc/localtime
# nano /etc/hostname

Type in the one-word, lowercase name of your VM. It can be absolutely anything you want, but you should probably make it something meaningful. Maybe “archlinux”. I’m going to assume you used “archlinux” and show you how to set up your hosts file if you did. If you didn’t, set up the hosts file with the name you actually used.
CTRL-x. SHIFT-Y. Enter. How could time itself start?
The Author Analogy easily explains many difficult questions about life, the universe, theology, religion, philosophy, epistemology, and the reality we find ourselves in.
Now change the hosts file.
# nano /etc/hosts

Type in the following with your VM name to the nano editor.
127.0.0.1 localhost
127.0.1.1 archlinux.localdomain archlinux

CTRL-x. SHIFT-Y. Enter. Now update some things and change some stuff:
# syslinux-install_update -i -a -m
# cd /boot/syslinux
# cp /usr/lib/syslinux/bios/menu.c32 .
# cp /usr/lib/syslinux/bios/vesamenu.c32 .
# cp /usr/lib/syslinux/bios/chain.c32 .
# cp /usr/lib/syslinux/bios/hdt.c32 .
# cp /usr/lib/syslinux/bios/reboot.c32 .
# cp /usr/lib/syslinux/bios/poweroff.c32 .
# cp /usr/lib/syslinux/bios/libutil.c32 .
# cp /usr/lib/syslinux/bios/libcom32.c32 .
# mkinitcpio -p linux
# passwd

Type in the new password for the root account (not your regular user account) for the new Arch Linux VM. Then we'll do more cool stuff:
# exit
# cd /
# umount /mnt/boot
# umount /mnt/home
# swapoff /dev/sda2
# umount /mnt
# sgdisk /dev/sda --attributes=1:set:2
# reboot

Let the system reboot. When it’s complete, it will ask you to log in. Log in as "root."
# root

Type in the root password that you created a couple of steps ago. Now update your mirrorlist again:
# nano /etc/pacman.d/mirrorlist

Move the local mirrors to the top of the list again.
CTRL-x. SHIFT-Y. Enter. Then edit your nameservers again:
# nano /etc/resolv.conf

Add these nameservers to the top of the nameserver list:
nameserver 8.8.8.8
nameserver 8.8.4.4

CTRL-x. SHIFT-Y. Enter. Then look up that thing again:
# ip link

Using the second set of data displayed from that command above, find the correct service domain and put it into the following line.
# sudo systemctl enable [email protected]
# ping google.com
# dhcpcd
# ping google.com

# useradd --home-dir /home/profe --create-home profe
# passwd profe
# nano /etc/sudoers

	Once the nano editor opens, find the line that reads:
	root ALL=(ALL) ALL

	Under that line, add the following line just like it:
	profe ALL=(ALL) ALL

	CTRL-x. SHIFT-Y. Enter. Now do some more stuff:
# exit
# ip link show
# sudo systemctl enable [email protected]
# sudo nano /etc/resolv.conf.head
	Add these nameservers to the empty text file:
	nameserver 8.8.8.8
	nameserver 8.8.4.4
	CTRL-x. SHIFT-Y. Enter. Now install a bunch more stuff and then reboot:
	
# sudo pacman -S xorg-server xorg-xinit xorg-apps
# sudo pacman -S xorg-iceauth xorg-sessreg xorg-xcmsdb xorg-xbacklight xorg-xgamma xorg-xhost xorg-xinput xorg-xmodmap xorg-xrandr xorg-xrdb xorg-xrefresh xorg-xset xorg-xsetroot mesa-libgl xterm
# sudo pacman -S xf86-video-vesa
# sudo pacman -S xfce4 xfce4-goodies sddm
# sudo reboot
# ping google.com

TESTING GUI...
# sudo pacman -S xorg-twm xorg-xclock
# startx
# exit

Install some more stuff and restart:
# sudo pacman -S ttf-liberation noto-fonts ttf-roboto ttf-anonymous-pro
# sudo pacman -S ttf-hack ttf-inconsolata noto-fonts-emoji powerline-fonts
# sudo pacman -S adobe-source-code-pro-fonts ttf-fira-mono ttf-fira-code
# sudo pacman -S ttf-ubuntu-font-family ttf-dejavu ttf-freefont
# sudo pacman -S ttf-droid terminus-font ttf-font-awesome
# sudo pacman -S gnome gnome-extra
# sudo systemctl enable gdm
# sudo reboot

Open terminal again manually in your GUI. Install some important apps:
# sudo pacman -S chromium
# sudo pacman -S firefox
# sudo pacman -S opera
# sudo pacman -S flashplugin
# gsettings set org.gnome.desktop.wm.preferences button-layout ":minimize,maximize,close"

Still in the terminal, clean up some font cache problems:
# sudo rm /var/cache/fontconfig/*
# rm ~/.cache/fontconfig/*

Now install Parallels Tools so you can copy between your operating systems and so you can share directories and stuff. Parallels Tools just worked right for me first try, so I will just link to another source for instructions for installing Parallels Tools.
In the future, to run a full system update, do this in the terminal:
# pacman -Syu
