ubuntu16.04的系统，前一天用的还好好的，今天开机就变成这样，我也看不懂啥意思。然后这是第二次出现这种情况了。第一次出现这种情况的时候我是重装系统。但是这次我的电脑里有自己以前做的一些东西。我不想让这些东西没了。请各位大神指点我应该怎么修复这个情况。只能重装系统吗？

0. 可能原因很多 優先檢查 硬盤分割 或 其 superblock

1. 使用 Ubuntu Live CD/DVD/USB 開機
登入 試用桌面 把下面指令 複製 貼進終端機 執行
1-1. sudo fdisk -lu /dev/sd*
1-2. sudo parted -l print
把結果全部直接 選取/複製/貼上來
不要摘錄 以免遺漏重要訊息
不要擷圖 方便回文直接引用你貼上來的資料 方便你閱讀

提示上说了/dev/sda1坏了，需要手动跑fsck

如果你没强制关机的话，注意你的硬盘

也就是说是硬盘的问题了？

没看懂什么意思［尴尬］

使用 Live USB 登入 試用桌面 功能之一 是 Recovery 功能
因為顯示文字說要檢查 fsck 你的分割區
而要檢查分割區 最好是在分割區 卸載時
試用桌面 提供 全部分割區 都是 卸載 的環境

我已经按照你说的方法执行了这些命令,出来一堆数据,我也不知道啥意思.然后我该怎么做呢.?

他说让你把输出的东西全部复制上来，不要截图

另外还建议直接用disks utility查看一下磁盘的SMART
可以参考

512 / 512的硬盘，这硬盘有年头了吧

恩。。是的呢，我这台是笔记本，是2010年买的，而且中间还修理过，换过硬盘，也不知道是什么硬盘。
因为第一次接触linux，刚入门就拿旧机子来试水。嘿嘿～

谢谢指点，但是为什么都是英文，我的天。看不懂。～～

可按照链接中的说法，安装 smartmontools 并用 smartctl 查看各类健康指标
登入 LiveCD / LiveUSB
连接网络
sudo apt-get install smartmontools
sudo smartctl -a /dev/sda
