几乎每次我尝试启动 Ubuntu 时，都会出现如下所示的紧急模式屏幕：
我尝试了列出的所有选项，但都无济于事。经过多次随机重启和/或强制关机后，我成功启动了 Ubuntu。我该如何解决这个问题？
我的 fstab 如下所示：
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda1 during installation
UUID=73afa7f9-6262-495e-b6a3-deda059da829 / ext4 errors=remount-ro 0 1
# /home was on /dev/sda5 during installation
UUID=68294dbf-0922-49bb-9cf6-2b1fd89b45f8 /home ext4 defaults 0 2
# swap was on /dev/sda6 during installation
UUID=750b0356-acad-4889-b95e-b9dd73f4151a none swap sw 0 0
我目前正在运行 17.04。但在旧版本中也遇到了同样的问题。
结果fdisk -l是：
