Ubuntu18.04挂载错误后修复

由于操作失误,把硬盘挂载到了/home,导致系统启动失败,用Ubuntu的安装U盘进入Try,然后输入以下命令:

sudo gedit ./etc/fstab

发现fstab文件是这样的:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda2 during installation
# /boot/efi was on /dev/sda1 during installation
#UUID=ECDD-DE35  /boot/efi       vfat    umask=0077      0       1
/swapfile                                 none            swap    sw              0       0
UUID=8f30f29b-b06a-4e21-b789-4f048c53e065 /home  ext4 errors=remount-ro 0 1

这明显不对,硬盘的挂载点应该是/而不是/home,将/home改成/.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda2 during installation
# /boot/efi was on /dev/sda1 during installation
#UUID=ECDD-DE35  /boot/efi       vfat    umask=0077      0       1
/swapfile                                 none            swap    sw              0       0
UUID=8f30f29b-b06a-4e21-b789-4f048c53e065 / ext4 errors=remount-ro 0 1

保存,重启,成功进入了系统.
