"fsck exited with status code 4" after choosing to boot Ubuntu

  • 772

When I turn on my computer, it goes into the Ubuntu interface and asks me what I want to boot into:

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

When I boot into the “Ubuntu” option, it just shows a command prompt that runs a few commands:

[   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)

This is my only computer and I don’t know much about Linux.

Thanks for your time!

  1. I figured it out, I just had to run 

    e2fsck -C0 -p on /dev/sdb2

    (since I was running it from a micro-sd card)

  2. I got it done by using:

    e2fsck -fy /dev/sda1
