我最近买了一个 Verbatim 1TB 的 USB 外置硬盘，并尝试安装全新的 Ubuntu 14.04 64 位。我的笔记本电脑中还有一个 320GB 的内置硬盘，里面装有 Windows 7。所有安装过程都很顺利，我在外置硬盘上创建了 3 个分区：Ubuntu 的 ext4 和 swap 分区以及数据的 ntfs 分区。我将 Ubuntu 放在第一个分区上。当我尝试启动系统时，问题出现了。我可以看到 GRUB 菜单上列出了 Ubuntu 和 Windows 7，但没有一个条目起作用。当我突出显示其中任何一个时，按 Enter 键，GRUB 菜单就会消失，屏幕变成紫色，什么也没发生。无论我选择 Ubuntu 还是 Windows 7，系统都无法启动。我做错了什么？请帮帮我。问候。Marcin PS。这是我的 grub.cfg 文件：
