我最近使用 WUBI 安装了 Ubuntu 14.04，安装后启动时显示错误：
Serious errors were found while checking the disk drive for /.
有三个选项：
press [I] to ignore, press [S] to skip mounting and press [M] to mount manually.
按下 后I，它显示/tmp无法安装并且我的 Ubuntu 无法启动。
在升级的“安装”阶段出现电源故障。再次启动后报如下错误：
init: udevtrigger main process (420) terminated with status 1
init: udevtrigger post-stop process (428) terminated with status 1
init: udevmonitor main process (419) killed by TERM signal
The disk drive for / is not ready yet or not present
Continue to wait; or press S to skip mounting or M for manual recovery
按 M 会给我以下消息：
Root filesystem check failed.
A maintenance shell will now be started.
CONTROL-D will terminate this shell and reboot the system.
当我启动 Ubuntu 时，我收到了这个错误：The disk drive for /tmp is not ready yet or is not present!我尝试跳过挂载，但它像命令提示符一样出现。
请帮我。
