Ошибки перед запуском grub'a.

[Knes]

Доброго всем времени суток!
Когда запускаю систему (ubuntu 11.04) перед загрузкой grub'а2 появляется 4 строчки текста примерно такого содержания:

Код: [Выделить]

error: no video mod activated
error: no video mod activated
warning: sintax error (missing slash) in 'blac'И дальше предлагает нажать любую кнопку для продолжения, после нажатия которой появляется grub2.
Появилось это после редактирования grub'a по этому ману
https://forum.ubuntu.ru/index.php?topic=74165.0 бекап не делал, на свой страх и риск и оказалось, что зря =\
Помогите привести в нормальный вид загрузку

Я даже менял их на чистые конфиги с установленной виртуальной машины, изменений не было.
Может можно как-нибудь сдефолтить эти настройки или переустановить сам груб?
