First need to partition your disk to allow UEFI setup. Use fdisk to setup the required partitions. Make sure you use the disk for the machine you are using.
fdisk -l
# Partition the drive (Your drive might be different)
fdisk /dev/sda
# Create GPT partion table
g

# Set the size for EFI partion

# Check that the partion looks correct and is bootable
fdisk -l
# Format the EFI file system
mkfs.fat -F32 /dev/sda1
# Create logical volumes
pvcreate --dataalignment 1m /dev/sda2
vgcreate volgroup0 /dev/sda2
lvcreate -l 100%FREE volgroup0 -n lv_root
# Add the device management module to kernel
modprobe dm_mod
# Make sure the volume group shows up
vgscan
# Make the volume group active
vgchange -ay
# Format the volume
mkfs.ext4 /dev/volgroup0/lv_root
# Mount the volume
mount /dev/volgroup0/lv_root /mnt
# Create the /mnt/etc directory and update fstab
mkdir /mnt/etc
genfstab -U -p /mnt >> /mnt/etc/fstab
# Install ArchLinux
pacstrap -i /mnt base git
# Finally, change to root in the new system
arch-chroot /mnt
After creating the partions and accessing new system clone this project into your new system so you can use the convenience scripts
