Acer Aspire 5 上的 Windows 更新后无法启动 Ubuntu

  • 772

在上次 Windows 更新（Windows 11 Home 24H2）后，我无法在 Ubuntu（24.04）上启动。我搜索了一些建议从启动修复磁盘启动（我这样做了）并使用启动修复的答案，但没有用。它没有显示“推荐修复”按钮，只有“创建摘要”按钮。摘要粘贴在下面。

编辑 1：这是我的磁盘信息。第一个是 1TB HD，我在其中保存视频文件、音乐、照片和一些备份。

以下是摘要。我使用 Acer 网站提供的 zip 文件更新了固件。

我尝试按照有关如何重新安装 grub 的分步指南进行操作，甚至害怕弄乱一切，但它也没有用。当我尝试挂载主分区时，它返回

mount: special device /dev/sdb2 does not exist

编辑 2：我尝试了这里写的前 2 个解决方案：a) 如果我按下 shift + esc，它会将我带到一个 sudo 不起作用的屏幕；b) 启动修复不起作用。正如我之前所说，它没有显示“推荐修复”按钮，只有“创建摘要”按钮。在高级选项中，它也不显示“修复 GRUB”选项；c) Windows 和 Ubuntu 都在 UEFI 上，但我不明白该怎么做；d) 我禁用了休眠和快速启动，但无法重新安装 GRUB。它一直告诉我/dev/sdb2不存在。我真的需要擦除我的 ssd 并重新安装吗？

编辑 3：我在启动修复磁盘终端上使用以下命令尝试了此解决方案：

sudo apt --fix-broken install

但它什么也没返回。然后我尝试

sudo update-grub

信息是

error: failed to get canonical path of '/cow'.

至少最后一个是有趣的。

我可以正常使用 Windows，甚至可以使用名为 Diskinternals Linux Reader 的软件访问 Ubuntu 上的文件，但我真的很想再次使用 Ubuntu。我只使用 Windows 玩游戏和一些在 Wine 上无法运行的应用程序，但我对 Linux 世界也非常陌生。如果有遗漏，请告诉我。
