Ubuntu啓動後進入GNU GRUB Version 2.02

Question Description：
電腦中裝Windows10和Ubuntu18.04,啓動Ubuntu後沒法正常進入，停留在GUN GRUB界面。

Solution:
一、Enter *Ubuntu
二、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.

三、編寫以下命令，fsck /dev/sdax並給出Y控制檯是否要求修復的東西：

(initramfs) fsck /dev/sda1 -y
