Ubuntu启动后进入GNU GRUB Version 2.02

Question Description：
电脑中装Windows10和Ubuntu18.04,启动Ubuntu后无法正常进入，停留在GUN GRUB界面。

Solution:
1、Enter *Ubuntu
2、exit

BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
Enter ‘help‘ for a list of built-in commands.

(initramfs) exit

/dev/sda1: 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 v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
Enter ‘help‘ for a list of built-in commands.

3、编写如下命令，fsck /dev/sdax并给出Y控制台是否要求修复的东西：

(initramfs) fsck /dev/sda1 -y
