Following the guide is mostly ok ; A word on something I completely forgot about :

When you use a graphical installer, it will both assist in creating / deleting / reorganizing partitions, then at formatting them or not, 
then in assigning their roles as "root", "home", or "swap" and so on ; I never realized those where completely independent actions, and that you
can partition or not, format or not, and, assign partitions with fstab later on independently.

==READ THE Fine MANUAL

(Assuming you have a thumbdrive ready and working)

Use F12 on Fatitude to get to the Choose Your Boot Media at startup
Load correct keymap :

# loadkeys fr-latin1

Network interface probably gonna be wlan0 ; in doubt, do ip link

Use iwctl to connect to the wireless network

[iwd]# station wlan0 scan
[iwd]# station device get-networks
[iwd]# station device connect SSID
[iwd]# exit
# ping archlinux.org

# timedatectl

Check partitions architecture :

# fdisk -l

Only format your root partition to install a fresh system on it. Add swap if you have swap:

# mkfs.btrfs -f /dev/sda6 (the -f option is to override former btrfs subvolumes)
# mkswap /dev/sda8

'

Mount the filesystems youre going to use on the /mnt folder of your live system:

# mount --mkdir /dev/sda2 /mnt/boot/efi
# mount --mkdir /dev/sda7 /mnt/home
# mount /dev/sda6 /mnt/
# swapon /dev/swap_partition

Yes, but

- No need to partition if there's no need to! (esp EFI) You'll run into a permissions nightmare on your /home, but that's better than loosing data :

 When the /home partition is mounted to /mnt/home at 'pacstrap' time, just chmod -r 777 the entire contents of the previous /home folder ; 
 when you make your new user, be sure to give it another name.

- Only format your system / partition (or root partition) with makefs.<type of filesystem>.

- It's ok to mount the EFI partition to /boot/efi and not simply /boot so as to not fill that small partition with everything in /boot, especially numerous kernels

 On my fresh install, the EFI partition is 260MB which is a factory default - and my /boot partition is already 268MB ; 
 ergo, it wouldn't fit, with just 4 kernels + the windows stub

Default install through pacstrap needs a lot more stuff, you'll probably want

- base-devel linux-lts os-prober pacman-contrib git grub efibootmgr

- grep rsync nano tar git iwd less - snapper ?

- gdm gnome networkmamager gedit - or any of your login manager and desktop environment of choice

- bluez bluez-utils usbutils git go zip wget

- firefox vlc smplayer gimp calibre

When you chroot in, it's normal for os-prober to not see the M$ partition, even if it is mounted ; you should re-run os-prober, and re-run grub-mkconfig, when you did reboot into the actual, fresh system.

don't forget to enable some systemd services, duh

- gdm.service

- NetworkManager.service

- bluetooth.service

with

 systemctl enable <name of unit>.service

If you are already in your graphic environment and instead need it to be enabled and start immediately (like for network), run

 systemctl enable --now <name of unit>.service

And make a basic user

Then create a basic user with

   useradd -m -G %wheel <name of user>

Add it to sudoers with

   EDITOR=nano visudo

Now you can reboot. Have you installed some network software? Have you enabled a graphic shell ? That's the core needs for a functional, fresh install to be tuned further as needed.

Set up aur or install flatpak for dropbox and ungoogled-chromium ; add python-gpgme for dropbox.

Other Housechores

Uncheck the os-prober-false at the bottom of /etc/default/grub ; generally speaking, tweak the grub file to your liking and re-run grub-mkconfig
Add the user to sudo with EDITOR=nano visudo
setup keyboard in gnome 
setup keyboard in GDM with localectl set-x11-keymap fr

Enable tap to click in gnome
setup wiregard

Good luck with btrfs, and snapper, and snap-pac, and grub-btrfs, and don't forget to hack mkinitcpio as described. Then try your luck with

# snapper rollback --ambit classic <snapshot number to rollback to>

The pyhton script snapper-rollback doesn't work for me, asks for some cquota definition that is said to be damageable to performance on the root partition ; note that I nevertheless blindly imputed some commands to enable quota, rescan them and such. sources suse and oracle.

AND IF YOU FAIL...

 Just re-do the whole install thing ; it is better to loose 20 minutes re-doing it than spending 20 days fixing it

For reference, and in memoriam of failing to remember one of the basics of building a Linux system, my current fstab (mysteriously auto-generated somehow) :

 # Static information about the filesystems.
 # See fstab(5) for details.
 
 # <file system>                               <dir>    <type>   <options>                                                          <dump> <pass>
