Here are the steps I used to install Omarchy in dual boot with Windows (inspired by https://www.youtube.com/watch?v=9jTk3K3ExaI):
- Use iwctl to connect to wifi
sfdisk /dev/nvme0n1-> make 1 EFI partition (nvme0n1p4 - 1G), 1 Linux partition (nvme0n1p5 - remaining space)- Format
mkfs.vfat -F 32 /dev/nvme0n1p4
mkfs.btrfs /dev/nvme0n1p5
- Create subvolumes (not sure if optional or mandatory). Do NOT create a subvolume for snapshots, it will raise errors during archinstall.
