如何修复主引导记录 (MBR)

fdisk 输出 1.75Tb 英特尔

我的外部备份磁盘，不是双启动系统

mix@mix-Latitude-E5530-vPro:~$ sudo fsck /dev/sdc
fsck from util-linux 2.39.1
e2fsck 1.47.0 (5-Feb-2023)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdc

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>

Found a dos partition table in /dev/sdc

请指教

答案1

您可能使用旧的引导加载程序 LiLo 来修复 mbr。

安装：

sudo  apt-get install lilo

跑步：

sudo lilo -M /dev/sdc mbr
