如何在GRUB2菜单中添加新的操作系统引导条目？
我对Linux很陌生，但在过去的几天里，我已经把它自己给了它一个机会。 我正在尝试一些不同的发行版，只是为了感受不同的版本，这是唯一真正让我挂断的东西。
我从Windows 7开始，然后我安装了Ubuntu 13.10（运行正常），然后我安装了Linux Mint。 但是，我没有办法启动Linux Mint，这就是我想要实现的目标。 我的目标是在启动时出现的Grub2菜单上有一个Linux Mint菜单项，以配合Ubuntu和Windows 7菜单项（以及我尚未使用的其他一些菜单项，如Advanced Ubuntu Options子菜单，以及memtest菜单条目）。
如果需要任何此类信息，请参阅GParted分区表中的一些信息，以及bootinfoscript输出的部分信息：
从GParted获取的分区信息和描述：
-
/dev/sda1是一个101.94 MiB主分区，其fat16文件系统标志为“diag” -
/dev/sda2是一个11.29 GiB主分区，带有ntfs文件系统，标志为“boot”，标签为“RECOVERY”。 根据/boot/grub/grub.cfg，这是Windows 7加载器所在的位置。 我没有从当前的Grub2菜单启动到Windows 7的问题。 -
/dev/sda3是一个275.12 GiB主分区，带有ntfs文件系统，标签为“OS”。 这个分区包含我最初在Windows上制作的所有文件，虽然有些文件是使用Ubuntu程序保存的（到目前为止，在操作系统中编辑文件没有任何问题，但如果出于某种原因这是不好的，请告诉我）。 -
/dev/sda4是一个171.01 GiB扩展分区。 此分区当前已安装。 除了Ubuntu 13.10和Linux Mint 16的逻辑分区外，它还包含交换分区：-
/dev/sda5是带有ext4文件系统的58.79 GiB逻辑分区，其中包含Linux Mint 16的安装。在GParted中，它表示此文件系统的挂载点是/。 这是唯一具有非空挂载点条目的分区。 我不知道该怎么做，而且我目前还不知道如何启动Linux Mint 16的方法。 -
/dev/sda6是一个19.56 GiB分区（我相信它被认为是主要的？）和“linux-swap”文件系统。 这是在我安装Ubuntu时自动创建的，但当我在尝试安装Linux Mint 16时遇到一些问题时，我手动增加了大约10 GB的大小。据我所知，Linux Mint 16目前已成功安装，但我不知道不知道怎么像我之前说过的那样启动它。 此分区当前已安装。 -
/dev/sda7是一个带有ext4文件系统的36.41 GiB逻辑分区，其中包含Ubuntu 13.10。 Ubuntu 13.10工作得很好，这就是我目前正在编写这个问题的内容。这个分区目前正在安装。

这是bootinfoscript输出（它很长，包括grub.cfg文件以及已在此处发布的sudo fdisk -l信息 – 但由于字符限制，有些必须省略）：

我不确定这个分区设置是否良好，因为我无法创建额外的主分区（最多4个），但我想，因为Ubuntu可以从扩展分区内启动，所以Linux Mint也应该能够所以我将Linux Mint添加到与Ubuntu（位于/dev/sda5 ）相同的扩展分区中的分区，但是在其自己的逻辑分区/dev/sda7 。
在/boot/grub/grub.cfg文件中，有几个menuentry单元。 如果从Grub2菜单启动Linux Mint的正确方法是为Linux Mint添加一个menuentry块，那么我想知道如何做到这一点。 如果有更好的方法让每个操作系统都有一个启动选项，请告诉我！
我在这里看到了一个类似的问题，但它似乎有点不同，因为用户没有在同一个扩展分区中包含两个操作系统分区，我不想只是在黑暗中拍摄并可能打破一些重要的事情意外地。
如果需要我在这里没有提供更多信息，我会密切关注这一点，所以请立即告诉我，我会尽我所能为您提供所需的任何信息。
非常感谢您的帮助！
您可以尝试使用update-grub来查看是否会检测到Linux Mint。 这应检查以确定安装了哪些操作系统。
或者，您可以尝试启动现场USB（或LiveCD）并运行install-grub /dev/sda了硬盘驱动器的install-grub /dev/sda 。 这将重新安装GRUB，并应再次检查其他操作系统。
