带有ubuntu的Windows虚拟机无法启动

我在Windows7 professional上安装了ubuntu虚拟机（不记得确切的版本）；当我尝试启动克隆时，会收到以下消息：

lvmetad is not active yet, using direct activation during sysinit
/dev/mapper/ubuntu--vg-root contains a file system with errors, check forced.
/dev/mapper/ubuntu--vg-root:
Inodes that were part of a corrupted orphan linked list found

/dev/mapper/ubuntu--vg-root: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
     (i.e., without -a or -p options)
fsck exited with status code 4
The root filesystem on /dev/mapper/ubuntu--vg-root requires a manual fsck

BusyBox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands.

 (initramfs)

我试着在谷歌上搜索解决方案，但所有的解决方案都建议使用SUDO并执行一系列操作——但是，我的问题是，我甚至无法在Ubuntu中访问终端！还有其他人面对这个问题并解决了吗

我执行了以下步骤：

  fsck /dev/sda6

  And enter Yes (y) to for each error. 

我重启了，一切都很好

键入fsck/dev/sda1（取决于受感染的驱动器“sda1、sda2等”）

如果出现错误，请重复fsck命令

出现提示时，按“是”

键入重新启动以重新启动系统

只需使用以下2个命令，即可解决问题并使系统恢复正常：

(initramfs) fsck /dev/sda1   //where *sda1* is the drive that complains the issue
(initramfs) reboot

这里提供的答案（第二个答案）解决了我的问题：这是这个问题的正确论坛。与其他答案的解决方案相同。
