Установленная Ubuntu на разделе HD с Vista, но не загружается

После попытки Ubuntu с Живого CD я решил установить его. Я разделил HD, где моя установка Vista путем уменьшения его на Vista, и я оставил пространство пустым, не форматируя его; затем я использовал живой CD для установки Ubuntu (12.04), которая, казалось, завершалась прекрасный.

При начальной загрузке не происходит никакой запрашивающей стороны GRUB, и Vista регулярно загружается, тогда как от ее управления дисками оснащают вакуум, который я оставил (16 ГБ) был занят разделом Ubuntu и подкачкой' один.

С этим существует 4 основных раздела, хотя был также еще один, я забыл размонтироваться прежде, чем установить (виртуальный CD).

Результаты с bootinfoscript следующие:
