################################### Details ####################################
# CURRENTLY WIP 
# This script is for installing a minimum install of arch to a computer. This
# script has been tested by the originator of the code to work in a Virtual
# Machine (VM). The goal is to have the system boot back into Arch with only a
# terminal so user can run another script to install everything else they need.
# While the script will auto download the scripts to do this it will also auto
# download a script for the user to install a basic graphical user interface
# (I3) and that script will not be required to be ran for a complete install.

##### Begin code to start install #####
# most of this code is copy pasted from old code and needs to be converted to match the style above in layout
# and UI for the user

### Verify the boot mode
if [ -d "/sys/firmware/efi" ]
then
	echo -e "${UEFI}UEFI boot ${NOTE}mode${CLER}"

echo -e "${NOTE}Checking for internet Connection:${CLER}"

else
	echo -e "${EROR}NOT CONNECTED${CLER} Please check your connection and try again"

	exit 1

### Partition, format, and mount the harddrives based on BOOT mode
if [ $BOOT = "UEFI" ]
then
	#sdX1 boot(512MiB)|SdX2 root(whats left after sdX1 or sdx3)|sdX3 swap(4GiB)
