我的台式电脑双启动 Ubuntu 18.04 和 Windows 7 时遇到了这个问题。Windows 运行良好，但我选择 Ubuntu 却出现了这个问题。
You are in emergency mode.
这是我的/etc/fstab文件：
# /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/sda7 during installation
UUID=ce0f60ea-7a52-4e22-9934-bf523b0a64db / ext4 errors=remount-ro 0 1
# /home was on /dev/sda8 during installation
UUID=9eaf47d2-a746-4da7-bc0d-6a7fc1bb5224 /home ext4 defaults 0 2
# swap was on /dev/sda6 during installation
UUID=a230235a-1495-4457-a217-5980939bc9b3 none swap sw 0 0
如何解决这个问题，请帮忙吗？
