I have ubuntu 16.04 installed.. whenever I boot the system and try to run ubuntu, busy box pops up. I do a manual check ---fsck -yf /dev/sda12--- and then reboot.. now the ubuntu boots properly but then after few minutes i am not able to save/write anything on ubuntu(says the the disk is read only) nor can i open my other partitions which i was able to access few minutes ago. I again restart my system and the same busybox appears. The cycle goes on and on. What should i do.. is my hard drive completely corrupted?

  • See my recent answer to askubuntu.com/questions/1019790/… and see if it applies to your situation. – heynnema Mar 31 '18 at 17:55
  • I have already done that.. also i did not install any windows driver – Mohit Kurani Apr 1 '18 at 10:54
  • What kind of primary disk do you use... hard disk or SSD? Open the Disks application and look at the SMART data to see if you're having a hardware problem. Do any of your other installed OS's have a problem also? – heynnema Apr 1 '18 at 12:31
  • A mistake from my side.. i did not run the command in recovery mode but in the normal mode... everything works perfectly now... thanks for the help, you are great :D – Mohit Kurani Apr 1 '18 at 15:20

Update #1: running fsck in recovery mode fixed the problem. I document this here to give the complete answer.

Lets first check your file system for errors.

To check the file system on your Ubuntu partition...

  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery mode
  • choose Root access
  • at the # prompt, type sudo fsck -f /
  • repeat the fsck command if there were errors
  • type reboot

If for some reason you can't do the above...

  • boot to a Ubuntu Live DVD/USB
  • start gparted and determine which /dev/sdaX is your Ubuntu EXT4 partition
  • quit gparted
  • open a terminal window
  • type sudo fsck -f /dev/sdaX # replacing X with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot
  • Thank you for share the solution it really helped me lots. Suddenly some directory was showing mount system/file system is read-only. I rebooted and it has fallen into initramfs – Ankur Loriya Dec 5 '18 at 7:41
  • This helped a lot after I shrank my root Ubuntu 18.04 partition – Juan C. Roldán Apr 20 '19 at 6:28

first, run the command


then check the number of partitions

it will look like

/dev/numve2: UUID="kksgasjhgdjh36876" TYPE="ext4" PARTUUID="bdmdmd7-iuuyuy-89jlh" /dev/numve4: UUID="kksgasjhgdjh36876" TYPE="ext4" PARTUUID="bjjlo-iuuyuy-89jlh"

now just run the command for all partitions:

fsck /dev/numve2 -y
fsck /dev/numve4 -y

after done for all partition just run :


and choose ubuntu it will work!!
