Test + SSH
network OK ?
ping -c3 archlinux.org
Install SSH
pacman -Sy pacman -S openssh vim /etc/ssh/sshd_config
#PermitRootLogin prohibit-password
PermitRootLogin yes
passwd
systemctl start sshd
Now we can connect from the network
Disk partitions

# gdisk /dev/nvme0n1 -l GPT fdisk (gdisk) version 1.0.10 The protective MBR's 0xEE partition is oversized! Auto-repairing. Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. Disk /dev/nvme0n1: 500118192 sectors, 238.5 GiB Model: KXG6AZNV256G TOSHIBA Sector size (logical/physical): 512/512 bytes Disk identifier (GUID): A49CF274-51B4-4CBF-BE13-5195151DBF6E Partition table holds up to 128 entries Main partition table begins at sector 2 and ends at sector 33 First usable sector is 34, last usable sector is 500118158 Partitions will be aligned on 2048-sector boundaries Total free space is 205869677 sectors (98.2 GiB) Number Start (sector) End (sector) Size Code Name 1 2048 206847 100.0 MiB EF00 EFI system partition 2 206848 239615 16.0 MiB 0C01 Microsoft reserved ... 3 239616 250570751 119.4 GiB 0700 Basic data partition 4 250570752 292513791 20.0 GiB 0700 Basic data partition 5 498378752 500115455 848.0 MiB 2700
The goal is to make a 16GB swap partition and the btrfs root:
gdisk /dev/nvme0n1
SWAP
Command (? for help): n
Partition number (6-128, default 6):
First sector (34-500118158, default = 292513792) or {+-}size{KMGTP}:
Last sector (292513792-498378751, default = 498378751) or {+-}size{KMGTP}: +16G
Current type is 8300 (Linux filesystem)
Hex code or GUID (L to show codes, Enter = 8300): 8200
Changed type of partition to 'Linux swap'
BTRFS root
Command (? for help): n
Partition number (7-128, default 7):

Hex code or GUID (L to show codes, Enter = 8300):

Save
Command (? for help): w Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING PARTITIONS!! Do you want to proceed? (Y/N): Y OK; writing new GUID partition table (GPT) to /dev/nvme0n1. The operation has completed successfully.
