Create partition one, leave 2048 sectors blank for the syslinux bootloader, and consuming the rest of the drive.
Create partition 1, leave 2048 sectors blank for the syslinux bootloader, and don't specify an end size, so that it takes the rest of the drive.
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
sgdisk -n 1:2048: /dev/vda
sgdisk --new 1:2048: /dev/vda
</syntaxhighlight>

Now that you have a partition, it will show as /dev/vda1. Format The partition as ext4

Set time Timezone
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime

== Prepraring to Boot ==
Create your initial ramdisk - The initial file system before the real one boots
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
mkinitcpio -p linux
</syntaxhighlight>
</syntaxhighlight>
Install syslinux
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
pacman -S syslinux
</syntaxhighlight>
</syntaxhighlight>
== Prepraring to boot ==
Install syslinux's GPT MBR (Master Boot Record) to the root of MBR. This will sit in the 2048 of reserved space from when we partitioned the drive.
<syntaxhighlight lang="bash">
dd if=/usr/lib/syslinux/bios/gptmbr.bin of=/dev/vda
</syntaxhighlight>
Prepare the /boot folder with syslinux's modules. The .c32 files that ship with syslinux are for systems that use a bios to boot. Symlink the bios modules into syslinux's boot folder.
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
ln -s /usr/lib/syslinux/bios/*.c32 /boot/syslinux/
</syntaxhighlight>
</syntaxhighlight>
Run the syslinux extlinux installer.
* extlinux is the filesystem variant of syslinux
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
extlinux --install /boot/syslinux
extlinux --install /boot/syslinux
</syntaxhighlight>
</syntaxhighlight>
By default, syslinux tries to boot /dev/sda3. Change it to boot /dev/vda1
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
sed -i 's#/dev/sda3#/dev/vda1#' /boot/syslinux/syslinux.cfg
</syntaxhighlight>
</syntaxhighlight>
== Reboot ==
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
exit
reboot
</syntaxhighlight>
</syntaxhighlight>
== Flavor ==
=== When Something Goes Wrong ===
If something goes wrong with rebooting and you end up back on the live cd, you don't need to start over.
Running the following 2 commands will bring you back to your Arch Linux Environment
<syntaxhighlight lang="bash">
<syntaxhighlight lang="bash">
mount /dev/vda1 /mnt
arch-chroot /mnt
</syntaxhighlight>
</syntaxhighlight>
Once you are back in the Arch environment, Check the following:
* You set the bootable flag on the partions
* You setup the syslinux boot loader correctly.
== PS:One Flavor ==
=== Salt ===
Some settings common to most of the computers at PS:One can be applied by running the following commands:
<syntaxhighlight lang="bash">
pacman -S salt-zmq
systemctl start salt-minion
salt-call state.highstate
</syntaxhighlight>
== reboot ==
=== Network Logins ===
Enable Network logins by joining the domain server.
After this command is run, the machine will support network authentication.
<syntaxhighlight lang="bash">
net ads join -U <your user name>
</syntaxhighlight>
