恢复 Ubuntu - 需要帮助

恢复 Ubuntu - 需要帮助

几周前,我在 Windows 10 的同时安装了 Ubuntu。昨天启动笔记本电脑时,我看到:

error: unknown filesystem.
Entering rescue mode...
grub rescue>

我从 USB 启动并按照本手册所述执行 grub 修复: https://help.ubuntu.com/community/Boot-Repair

启动修复启动信息摘要:http://paste.ubuntu.com/26476661/

修复 grub 后,我重启了电脑,没有给出选择操作系统的选项,但 Windows 自动启动并进行了长时间的更新!再次重启,只有 Windows 启动(即使我按住左 Shift 键)。从 USB 启动并在终端中输入sudo fdisk -l

我不记得 Ubuntu 安装在哪个分区 sda4 还是 sda5,但无论如何,据我所知 Ubuntu 消失了?

这是运行后的输出sudo blkid(如果有帮助的话)。

有人可以帮我恢复 Ubuntu 上的文件(主要是 .pdf 书籍和一些 python 脚本 .py)吗?
