In the console use df -h to list drives and mount locations. The 2 that where just made should be mounted on /target/ and /target/boot/efi/ umount both of the partitions then mount /dev/sda2 /mnt/choose the /dev/•••• drive that was mounted on /target/ cd mnt/then ls to check for @rootfs, next mv @rootfs @, then btrfs subvolume create @home Use these commands for an SSD

mount -o noatime,compress=zstd,subvol=@ /dev/sda2 /target/
mkdir -p /target/boot/efi/
mkdir -p /target/home
mount -o noatime,compress=zstd,subvol=@home /dev/sda2 /target/home
mount /dev/sda1 /target/boot/efi/

Next edit fstab, most likely with nano editor nano /target/etc/fstab. Edit the UUID with btrfs, should be the first one. Replace defaults,subvol=@rootfs with noatime,compress=zstd,subvol=@ then use CTRL+k to cut then CTRL+u twice to create a second UUID, add home to the mount point and at the end of subvol=@ now press CTRL+o to save, then CTRL+x to exit.
