Разрешение отклонило: '/var/lib/partman/stopfifo' при попытке установить 14.04 как двойная загрузка с Windows 8

Я пытаюсь установить UBUNTU 14.0.4.1 LTS наряду с окнами 8 к двойной загрузке. Я следовал за этим вопросом и сделал все шаги neccesary, Установив Ubuntu Вместе с Предварительно установленным Windows с UEFI

Спецификации:

• Thoshiba p75-A7100
• Прибыл установленный с Windows 8.

Я сделал это:

• UEFI включен
• Безопасная начальная загрузка отключена

Я пытаюсь установить человечность от живого CD. Установщик застревает в Prepare to Install phase с ниже отслеживания стека в отладке.
