在将 linux 安装到 macbook pro 6,2 (2010) 上作为单启动系统时，我在 live usb 上使用 linux 安装程序时收到以下错误：“执行‘grub-install /dev/sda’失败。这是一个致命错误。”我之前“成功”安装了 mint，但它崩溃了，大概是因为视频问题。我根本不想在机器上安装 mac os。似乎 sda 上有一个用于 grub 安装的 EFI 分区（我假设这是 grub 的安装位置？）。我运行了“bootinfoscript”，结果如下。任何想法都值得赞赏。谢谢：

检查您的设置：系统设置->软件更新->检查所有 Ubuntu 软件->其他软件->已检查 Canonical 合作伙伴。
打开终端 CTL + ALt + T
更新设置sudo apt-get update && apt-get upgrade
检查所有包 ->sudo apt-get -f install
安装新内核sudo apt-get dist-upgrade
更新你的 grub->sudo update-grub
重启 ->sudo reboot
