Không có hệ thống tập tin gốc root Lỗi khi preseising

Tôi đang cố gắng thực hiện cài đặt tự động máy chủ Ubuntu (11.10). Công thức phân vùng của tôi là ở đây:

Tôi luôn luôn kết thúc vì lỗi:

Không có hệ thống tập tin gốc được xác định.

Vui lòng sửa lỗi này từ menu phân vùng.

lỗi_msg

Bằng cách chọn tiếp tục, tôi chỉ nhận được cùng một màn hình.

Nhóm khối lượng và khối lượng logic được tạo thành công. Tôi đã dành gần hai ngày để thử nghiệm và googling. Bây giờ tôi thực sự không biết tôi nên thử cái gì bây giờ. Cảm ơn vì bất kì sự giúp đỡ.

rắc rối là ở dòng này:

  mountpoint { / } .              \

Nó sẽ giống như thế này:

  mountpoint{ / } .              \

Khoảng trống giữa mountpointvà {không được cho là ở đó.

thở dài...
