Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would not act on the boot.

答案1

  1. 从 Ubuntu Live CD 启动并选择尝试而不安装。
  2. 从键盘打开终端 ctrl + alt + T 或单击键盘上的窗口，然后在搜索框中输入终端
  3. 在终端中输入fsck /dev/sda2然后输入，如果需要root则添加sudosudo fsck /dev/sda2

**注意：sda2 是系统运行的位置，要知道它是相同还是不同的数字，请从程序菜单中打开磁盘程序，通过搜索找到终端，然后选择硬盘并单击您将在大小后找到的文件系统分区，设计 /dev/sdX0，其中 x 是字母，0 是数字，写下您将找到的内容而不是 a2、x0...

答案2

让我给你一个更新，Bassem。这是我尝试打开 GParted 的操作。它显示了 2 个分区。

/dev/sda (111.79 GiB) 分区：未分配！文件系统未分配 /dev/sdg (14.92 GiB) 分区：/dev/sdg 文件系统：iso9660 Ubuntu 22.04 LTS amd64

ubuntu@ubuntu:~$ sudo fsck /dev/sda2 fsck from util-linux 2.37.2 e2fsck 1.46.5 (30-Dec-2021) fsck.ext2: 尝试打开 /dev/sda2 时没有此文件或目录 可能不存在设备？ ubuntu@ubuntu:~$ sudo fsck /dev/sda fsck from util-linux 2.37.2 e2fsck 1.46.5 (30-Dec-2021) ext2fs_open2: 超级块中的魔法数字错误 fsck.ext2: 超级块无效，正在尝试备份块... fsck.ext2: 尝试打开 /dev/sda 时超级块中的魔法数字错误

无法读取超级块，或者超级块未描述有效的 ext2/ext3/ext4 文件系统。如果设备有效，并且确实包含 ext2/ext3/ext4 文件系统（而不是交换或 ufs 或其他文件系统），则超级块已损坏，您可以尝试使用备用超级块运行 e2fsck：e2fsck -b 8193 或 e2fsck -b 32768

答案3

Richard 按照这些图片我在你的报告中发现你的分区是 sdg4

1-打开磁盘

2-选择系统分区并将其设备信息复制到设备大小前面

3- 在终端中输入fsck，然后按空格键并粘贴您复制或写入的信息，然后按回车键我认为您fsck /dev/sdg4 可能需要添加 sudo root，因此将输入sudo fsck然后粘贴有关系统分区的设备信息。我认为它会sudo fsck /dev/sdg4

注意：您必须在实时 CD 上“尝试不安装的 Ubuntu”才能在运行已安装的系统上工作，它会说无法卸载它，而且只有系统分区可以通过 FSCK 修复。

您还可以使用 Ubuntu 将硬盘作为从属硬盘放在正在运行的主硬盘上，然后选择字母和数字，在这种情况下，如果没有更多设备，可能会给出 sdb2 而不是 sdb1。

打开磁盘程序
