启用 Windows 10 升级后恢复数据和 Linux 分区

启用 Windows 10 升级后恢复数据和 Linux 分区

我的笔记本电脑上有双启动 Windows 8 和 Ubuntu,并且有一个 NTFS 数据分区。

强制迁移到 Windows 10 后,我的计算机在 grub 救援模式下重新启动,并且我能够在 ubuntu 或 Windows 上启动。

error: no such partition.
Entering rescue mode...
grub rescue>

因此我尝试在实时 USB 上使用启动修复功能重新安装 grub,但是没有作用并且我的计算机现在直接在 Windows 上启动...

当前分区信息(bootInfo):

Disk /dev/sda: 512.1 GB, 512110190592 bytes
255 heads, 63 sectors/track, 62260 cylinders, total 1000215216 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes

Partition  Boot  Start Sector    End Sector  # of Sectors  Id System

/dev/sda1    *          2,048       718,847       716,800   7 NTFS / exFAT / HPFS
/dev/sda2             718,848   208,764,927   208,046,080   7 NTFS / exFAT / HPFS
/dev/sda3         826,302,464 1,000,214,527   173,912,064   5 Extended
Invalid MBR Signature found.
/dev/sda5     ? 1,524,864,998 5,236,647,937 3,711,782,940  c0 CTOS
/dev/sda6     ? 5,092,567,351 8,619,976,874 3,527,409,524  c5 DRDOS secured Extended
/dev/sda4         208,764,928   826,302,463   617,537,536   7 NTFS / exFAT / HPFS

/dev/sda5 ends after the last sector of /dev/sda
the logical partition /dev/sda5 is not contained in the extended partition /dev/sda3
/dev/sda5 overlaps with /dev/sda6
/dev/sda6 ends after the last sector of /dev/sda
the logical partition /dev/sda6 is not contained in the extended partition /dev/sda3

/dev/sda1 -> MBR(分区已正确识别)

/dev/sda2 -> OS windows(分区已正确识别)

/dev/sda3 -> 扩展分区

-> /dev/sda5 逻辑 Ubuntu 分区(可能是 /)

-> /dev/sda6 逻辑 Ubuntu 分区(可能是 /home)

在 gparted 上,我看到 /dev/sda3,但没有显示逻辑分区

/dev/sda4 -> NTFS 数据分区

在 gparted 上,当我尝试挂载该分区时出现以下错误(在 Windows 上也无法挂载该分区...):

Unable to detect file system! Possible reasons are:
- The file system is damaged
- The file system is unknown to GParted
- There is no file system available (unformatted)
- The device entry /dev/sda4 is missing

我现在要做什么才能恢复我的 NTFS 数据和 Linux 分区?

谢谢您的帮助(抱歉我的英语不好)。
