![如何向 GRUB2 菜单添加新的操作系统启动项?](https://linux22.com/image/846994/%E5%A6%82%E4%BD%95%E5%90%91%20GRUB2%20%E8%8F%9C%E5%8D%95%E6%B7%BB%E5%8A%A0%E6%96%B0%E7%9A%84%E6%93%8D%E4%BD%9C%E7%B3%BB%E7%BB%9F%E5%90%AF%E5%8A%A8%E9%A1%B9%EF%BC%9F.png)
我对 Linux 还很陌生,但过去几天我决定尝试一下。我尝试了几个不同的发行版,只是为了感受一下不同的版本,这是唯一让我感到困惑的事情。
我先从 Windows 7 开始,然后安装了 Ubuntu 13.10(运行完美),然后安装了 Linux Mint。但是,我没有办法启动 Linux Mint,而这正是我想要实现的。我的目标是在启动时出现的 Grub2 菜单上有一个 Linux Mint 菜单项,与 Ubuntu 和 Windows 7 菜单项一起使用(还有一些我尚未使用过的菜单项,如高级 Ubuntu 选项子菜单和内存测试菜单项)。
如果需要任何此类信息,以下是来自 GParted 分区表的一些信息以及部分输出bootinfoscript
:
来自 GParted 的分区信息和描述:
/dev/sda1
是一个 101.94 MiB 主分区,采用 fat16 文件系统,带有“diag”标志/dev/sda2
是一个 11.29 GiB 的主分区,采用 ntfs 文件系统,带有“启动”标志和“恢复”标签。根据/boot/grub/grub.cfg
,这是 Windows 7 加载程序所在的位置。我从当前的 Grub2 菜单启动 Windows 7 没有任何问题。/dev/sda3
是一个 275.12 GiB 的主分区,带有 ntfs 文件系统,标签为“OS”。此分区保存了我最初在 Windows 上创建的所有文件,尽管有些文件已使用 Ubuntu 程序保存(到目前为止,跨操作系统编辑文件没有出现任何问题,但如果出于某种原因出现问题,请告诉我)。/dev/sda4
是一个 171.01 GiB 的扩展分区。此分区当前已挂载。它包含交换分区,以及 Ubuntu 13.10 和 Linux Mint 16 的逻辑分区:/dev/sda5
是一个 58.79 GiB 的逻辑分区,具有 ext4 文件系统,其中包含 Linux Mint 16 的安装。在 GParted 中,它显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,而且我目前也不知道如何启动当前所在的 Linux Mint 16。/dev/sda6
是一个 19.56 GiB 分区(我相信它被认为是主分区?),带有“linux-swap”文件系统。这是我在安装 Ubuntu 时自动创建的,但在尝试安装 Linux Mint 16 时遇到一些问题时,我手动将其大小增加了约 10 GB。据我所知,Linux Mint 16 目前已成功安装,但我不知道如何像我之前所说的那样启动它。此分区当前已安装。/dev/sda7
是一个 36.41 GiB 的逻辑分区,文件系统为 ext4,其中包含 Ubuntu 13.10。Ubuntu 13.10 运行良好,我目前就是在它上面写这个问题的。此分区当前已挂载。
这是bootinfoscript
输出(它很长,包括文件grub.cfg
以及sudo fdisk -l
已经发布在这里的信息 - 但是由于字符限制,有些信息必须省略):

我不确定这个分区设置是否好,因为我无法创建额外的主分区(最多 4 个),但我想既然 Ubuntu 可以从扩展分区内启动,那么 Linux Mint 也应该可以,所以我将 Linux Mint 添加到与 Ubuntu 位于同一扩展分区(在/dev/sda5
)的分区中,但在它自己的逻辑分区中/dev/sda7
。
文件中/boot/grub/grub.cfg
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 添加菜单项块,那么我想知道该怎么做。如果有更好的方法让每个操作系统都有一个在启动时启动的选项,也请告诉我!
我看到了一个类似的问题这里但情况似乎有点不同,因为该用户的同一个扩展分区内没有包含两个操作系统分区,而且我不想只是在黑暗中射击并可能意外破坏一些重要的东西。
如果需要我未在此处提供的更多信息,我会密切关注,因此请立即告诉我,我会尽力为您提供所需的任何信息。
非常感谢您的帮助!

您可以尝试update-grub
看看它是否能检测到 Linux Mint。这应该会检查安装了哪些操作系统。
或者,您可以尝试从 Live USB(或 LiveCD)启动并grub-install /dev/sda
在安装硬盘的情况下运行。这将重新安装 GRUB 并再次检查其他操作系统。
