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?
Lets first check your file system for errors.
For Ubuntu 17.10 or older...
#
prompt, typesudo fsck -f /
fsck
command if there were errorsreboot
For Ubuntu 18.04 or newer... (or if the above steps don't work for you)...
terminal
window by pressing Ctrl+Alt+Tsudo fdisk -l
sudo fsck -f /dev/sdXX
, replacingsdXX
with the number you found earlierfsck
command if there were errorsreboot
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:
after done for all partition just run :
and choose ubuntu it will work!!
