# Arch Linux wiki for Dell XPS 15 9550
# https://wiki.archlinux.org/index.php/Dell_XPS_15_(9550)

### INTRODUCTION
#   A simple dual-boot UEFI installation for Arch Linux without any file system encryption.
#   Assumes that Windows has already been installed beforehand
#   Follows the official installation guide: (https://wiki.archlinux.org/index.php/installation_guide)
#   Uses rEFInd boot manager as the UEFI boot manager (https://wiki.archlinux.org/index.php/REFInd)

### 1. DOWNLOAD TO USB
#     a. Download the official Arch Linux ISO from https://www.archlinux.org/download/
#     b. Copy to a USB drive
#        Windows users: use Rufus with default settings in ISO mode (https://rufus.ie/)

### 2. BIOS SETTINGS
#     a. Disable secure boot on XPS 15
#     b. Ensure that the NVMe SSD is set to AHCI mode instead of RAID
#     c. Boot from the USB

### 3. PRE-INSTALLATION
#     a. Set keyboard layout if necessary. Defaults to US keyboard layout.
        ls /usr/share/kbd/keymaps/**/*.map.gz # list available keyboard layouts
        loadkeys $LAYOUT # loads keyboard layout -- replace $LAYOUT with layout
#     b. Connect to WiFi
        wifi-menu # (verify internet connection by pinging wiki.archlinux.org or google.com)
#     c. Update system clock
        timedatectl set-ntp true
#     d. Disk Partitioning
        fdisk -l # Find the main disk drive for partitioning
        cgdisk $MAIN_DISK_DRIVE # e.g. cgdisk /dev/nvme0n1
        # example partitioning for dual-boot setup on a 512GB SSD
        # swap - about 8GB     - hex code 8200 (for Linux swap)
        # root - about 64 GB   - hex code 8304 (for Linux x86-64 root(/))
        # home - about 100 GB  - hex code 8302 (for Linux /home)
        # rest of drive already taken up by Windows install
#     e. Format and initialize partitions
        mkfs.ext4 $ROOT_PARTITION # e.g. /dev/nvme0n1p1
        mkfs.ext4 $HOME_PARTITION # e.g. /dev/nvme0n1p2
        mkswap $SWAP_PARTITION    # e.g. /dev/nvme0n1p3
        swapon $SWAP_PARTITION
#     f. Mount the file systems
        mount $ROOT_PARTITION /mnt
        mount $HOME_PARTITION /mnt/home
        mkdir -p /mnt/boot/efi
        # Mount the boot EFI partition. This is the drive partition that shows up with EFI label from fdisk -l
        mount $EFI_PARTITION /mnt/boot/efi

### 4. INSTALLATION
#     a. Install to mounted partitions
        pacstrap /mnt base base-devel zsh vim git efibootmgr refind-efi dialog wpa_supplicant
#     b. Generate fstab
        genfstab -U /mnt >> /mnt/etc/fstab
        # Ensure that the fstab contains declarations in /mnt/etc/fstab
#     c. Enter the new system with chroot
        arch-chroot /mnt /bin/bash # use bash in chroot
#     d. Setup system clock and timezone
        ln -sf /usr/share/zoneinfo/REGION/CITY /etc/localtime # set time zone
        # e.g. ln -sf /usr/share/zoneinfo/America/Los_Angeles /etc/localtime
        hwclock --systohc # generates /etc/adjtime for UTC
#     e. Localization
        # uncomment en_US.UTF-8 UTF-8 and other locales in /etc/locale.gen, then run:
        locale-gen
        echo LANG=en_US.UTF-8 >> /etc/locale.conf
        echo LC_ALL=C >> /etc/locale.conf
#     f. Hostname
        echo $HOSTNAME > /etc/hostname
#     g. Recreate initramfs (if necessary)
        mkinitcpio -p linux
#     e. Set root password
        passwd
#     f. Add a real user (use /bin/zsh for shell)
        useradd -m -g users -G wheel -s /bin/zsh $USER_NAME
        passwd $USER_NAME # set user password

### 5. REFIND-EFI SETUP
##  NOTICE: When refind-install is run in chroot, /boot/refind_linux.conf is populated with kernel options from the live USB, not the one on which it is installed.
##          The below steps are to install refind and fix the boot parameters
#     a. Run refind-install script
        refind-install
#     b. Edit refind_linux.conf in /boot/ folder
        # ensure that /boot/refind_linux.conf has the correct entries
        # e.g.
        #      "Boot using default options"     "root=UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX rw add_efi_memmap"
#     c. Exit chroot
        exit
#     d. Unmount and reboot to new system (remember to unplug the USB)
        umount -R /mnt
        swapoff -a
        reboot

### 6. NEW SYSTEM SETUP
