# Installing Arch

### Load pt keys with:

loadkeys pt-latin1

### Make sure it is in UEFI. To do this write: 

ls /sys/firmware/efi/efivars

### If there are results everything is nice.

### Establish network connection, maybe use cable for this one, a lot easier, configure the wireless:


timedatectl set-ntp true

### To list partitions, use: 

fdisk -l

### There needs to be:
### - A /mnt/boot or /mnt/efi with 260-512 MB;
### - A /mnt which is the entirety of the device;
### - A swap, make it around 1.25* of RAM, that should do it (a lot of varying opinions on this);

### Check what is the drive you are going to install Arch on, and run:

fdisk /dev/sdX

### Where X is the name of the partition, then wipe the partitions that you want delete by entering 'd' and then deleting the respective partition.  

### To create a new partition write 'n', let the number of the partition be default, the starting point be default, and for the size you can write '+#X', where X is the format (G for gigabytes, M for Megabytes), and # is the number of MB or GB for the partition.

### If fdisk asks you to override the signature, choose Yes.

### Create a partition of 512M for the /mnt/boot/efi, a partition for the SWAP, and another for the /mnt. 

### Now we need to actually make the partitions usable, so we use:

mkfs.ext4 /dev/sdXY (where XY are the partitions created for /mnt/boot/efi and /mnt partitions)

## Important! If you have an EFI system, create the boot partition with:

mkfs.fat -F32 /dev/sdXY 

mkswap /dev/sdXY && swapon /dev/sdXY (where XY is the partition created for the swap file)

### Now we need to mount the partitions using

mount /dev/sdXY /mnt/boot/efi
mount /dev/sdXZ /mnt/

### where XY is the partition for the boot and XZ is the root partition.
### Now just make sure everything is setup nicely running: 

lsblk

### Now to install Arch!

pacstrap /mnt base base-devel linux linux-firmware (more programs you want to install)

### Now that we have Arch Linux installed, we need to generate our file system tab, stored in /etc/fstab. For this we run: 

genfstab /mnt >> /mnt/etc/fstab

### Let's hop into our Arch Linux installation: 

arch-chroot /mnt

### Nice, we're getting there. Now to install GRUB

pacman -S grub (and efibootmgr if you have UEFI)

### All that's left is installing and configuring grub.

grub-install /dev/sdX (not sdXY, the file system, and not the partition)

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

### Setup a password using: 

passwd

### Setup locale:

nano /etc/locale.gen

(uncomment locale you want, like en_GB things)

nano /etc/locale.conf 

(add LANG=en_GB.UTF-8) 

locale-gen

nano /etc/vconsole.conf 

(add KEYMAP=pt-latin1, change it to whatever keymap you want)

### Timezone information 

ln -sf /usr/share/zoneinfo/ZONEOFYOURCHOOSING /etc/localtime

### Now setup hostname 

nano /etc/hostname 

(add a single word to be your hostname)

nano /etc/hosts

(add this, and replace myhostname with the word you wrote above)

127.0.0.1	localhost
127.0.1.1	myhostname
::1		localhost ip6-localhost ip6-loopback

### Configure a NetworkManager

sudo pacman -S networkmanager
sudo systemctl enable NetworkManager

### Arch is installed! Exit your arch-chroot by entering 'exit', and then do 'umount -R /mnt' to unmount all partitions.

### Reboot, and then in the new Arch Linux install do: 

useradd -m -g wheel username (change this to what you want)

passwd username 

### Now edit the /etc/sudoers file and uncomment the %wheel statement

### Edit the /etc/pacman.conf, and uncomment multilib

### Now exit, log into your user and setup basic folder structure: 

cd ~

mkdir Documents Downloads Music Games Pictures Desktop 

sudo pacman -S git 

### Then clone this repo, and after this, I made a script to automate everything :) and run the archFullSetup, and you're good to go!
