someone said comment(#) the error partition on /etc/fdisk but what if the partition is your root partition
note these things if you have a problem
a.
login as how login gives you access to your system
b. #mount -n -o remount,rw /
c. #e2fsck -p /dev/hda3 (here hda3 my root )
d. if it does not work
e. #fsck /dev/hda6 (respond +ve for all the questions i.e. default answer)
f. Neglect any last message and just reboot
g. Now it should work in case of hard disk
h. If you have any problem with flash drive it is wise to comment out (#) in /etc/fstab with first executing (b.) as above
Thanks
