Dell XPS 13 更换主板后,硬盘无法访问

我在 Dell XPS 13 上安装了双启动设置,安装了 Windows 10 和 Ubuntu 18.04。主板坏了,戴尔更换了主板。和往常一样,这破坏了我的 grub 设置。我按照通常的方式继续操作,从 USB 驱动器启动到 ubuntu,然后尝试安装我的 linux 分区,但现在我的硬盘不可见。

我想知道我的问题是否是由于我原来的驱动器上的 Windows 分区不知何故被破坏了。在更换主板之前,我无法从 grub 菜单进入它。更换主板后,我也无法进入 Windows 10。我可以进入 dos 提示符,告诉我 windows 仍然以某种形式存在,但我无法让 windows 自我修复。

以下是从屏幕运行的常用命令的输出try ubuntu

来自:( sudo fdisk -l 我看到的只有 /dev/sda,也就是 USB 驱动器)

同样,gparted只显示 USB 驱动器,没有硬盘驱动器。

无奈之下,我尝试重新安装 ubuntu,但甚至无法做到这一点:唯一可见的驱动器是 USB 驱动器 /dev/sda。

如能提供任何帮助我将非常感激。
