Не может установить город: ошибка во время установки

Я пытался установить город, и я получил ошибку.

Я использовал следующие команды:

sudo add-apt-repository ppa:n-muench/burg
sudo apt-get update && sudo apt-get install
sudo apt-get install burg burg-common burg-emu burg-pc burg-themes burg-themes-common

Пока здесь все не пошло прекрасное, но после следующей команды я получаю ошибку:

aneal@ubuntu:~$ sudo burg-install /dev/sda3 && sudo update-burg

/usr/sbin/burg-setup: warn: Attempting to install GRUB to a partition instead of the MBR.  This is a BAD idea..
/usr/sbin/burg-setup: warn: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
/usr/sbin/burg-setup: error: if you really want blocklists, use --force.

Теперь я думаю, что не могу перезапустить. Я предполагаю, загружаюсь ли я, я получу спасение личинки, и я знаю, как преобладать над этим, моя проблема состоит в том, как установить город в MBR теперь.

И то же - результат с sda2.
