"fsck退出状态代码4“后，选择启动Ubuntu

Question

当我打开我的计算机时，它会进入Ubuntu界面，并询问我想要引导什么：

Ubuntu
Advanced system options for ubuntu 
Windows boot manager (on /dev/sda1)
System setup

当我引导到“Ubuntu”选项时，它只显示一个命令提示符，它运行一些命令：

[   3.075355] sd 4:0:0:0 [sdb] No Caching Mode page found 

[   3.075388] sd 4:0:0:0 [sbd] Assuming Drive cache: write through

/dev/sdb2 contains a file system with errors, check forced

  Inode 2766781 extend tree (at level 2) could be narrower. IGNORED.

Inode 3938804, end of extent exceeds allowed value

 (Logical Block 387, physical block 19229549, Len 1)

/dev/sbd2: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.

(i.e., without -a or -p options)

fsck exited with status code 4

The root filesystem on dev/svb2 requires a manual fsck
BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3.2) built-in shell (ash)

Enter ‘help’ for a list of built in commands.
(initramfs)

这是我唯一的一台电脑，我对Linux不太了解。

耽误您时间，实在对不起!

Answer 1

我想出来了，我只需要跑

e2fsck -C0 -p on /dev/sdb2 

(因为我是用微sd卡运行的)

Answer 2

我用：

e2fsck -fy /dev/sda1
