Windows отсутствует в меню GRUB [дубликат]

7

Когда я включаю компьютер, я вижу GRUB и загружаюсь в Ubuntu. Но я не могу загрузиться в Windows, потому что я не вижу его в GRUB.

Я попробовал как загрузку, так и sudo update-grub безрезультатно. Вероятно, стоит упомянуть, что BIOS использует UEFI для управления загрузкой.

У меня Ubuntu 12.10 и Windows 7 установлены где-то на одном диске.

Почему MBR на / dev / sdb?

Это вывод bootinfoscript:

Просто выполните %код% и sudo update-grub . И это должно быть сделано.
В случае, если ваша Windows находится на sudo update-initramfs -u , команда /dev/sda1 должна содержать sudo update-grub (немецкая локализация)

У меня была аналогичная проблема в Ubuntu 12.04 LTS. Запустите sudo update-grub . Вы также можете проверить Boot Repair .

Я установил Windows 7 и потерял grub как-то. Переустановил его на диск 10.10, используя этот v в терминале.

    sudo mount /dev/sda4 /mnt
    sudo grub-install --root-directory=/mnt /dev/sda

, тогда окна не появятся в grub, поэтому я загрузился в Ubuntu и

    sudo update-grub

он подумал о min, а затем возвратил найденные окна 7 (загрузчик) на / dev / sda (или что-то в этом роде), а затем вернулся «done», и я перезапустил его и зафиксировал его.

попробуйте обновить grub изнутри операционной системы, в которой есть интернет (idk, если это связано, я не пытался обновлять grub без Интернета)

удачи !!
