12.04 只能从重启或实时 USB 重启启动 - 绝望

  • 772

我只能通过首先从我的 live USB 启动并在 grub 中更改启动驱动器来启动到 Ubuntu。即，不是从硬盘安装。引导后通过更改 BIOS 中的磁盘优先级重新引导是完美的。

在这个问题的整个历史过程中，我遇到了各种错误：Out of disk，“未知文件系统”（我当前的错误）。我尝试通过重新安装 GRUB、使用boot-repair重新安装 GRUB 和其他几种方法来修复它，但没有结果。感谢上帝，您不需要经常关闭 Ubuntu。

下面是结果fdisk -l

    1.)Try Ubuntu从 Live CD中选择

    2.) 启动引导修复。

    3.) 点击Advanced option

    4.) 转到GRUB options选项卡

    5.) 勾选out-of-disk选项

    6.) 点击Apply

    重启系统。

    如果这不起作用sudo apt-get install grub2，请在系统启动时从终端尝试，然后使用Grub-customizer将其放置在/dev/sda1. 在 Ubuntu 14.04 中安装 Grub Customizer 来管理你的 Grub Bootloader

  2. 可能发生了什么

    GRUB 可能已安装在您的 U 盘上。

    我该如何（可能）修复它？

    1. 输入 Ctrl + Alt + T
    2. 类型sudo apt-get install grub2

    如果这不起作用，请告诉我，因为我想再次尝试提供帮助。
