Doing a manual partition for dual boot with windows, partition type does not have btrfs available.
Drive is nvme0n1, currently have 6 gpt partitions p1 through p6, 2 efi - windows and /boot/efi - 2 ntfs windows stuff, 1 ext4 for /boot and a 16.8mb unformatted data I'm afraid to delete, and 721gb of free space.
