Hi everyone,
I am using Centos 6 machine.In order to understand my machine I have been following one of the book for Centos. Today, unfortunately I have added LABEL=/home /home ext3 defaults,usrquota,grpquota 1 2 in /etc/fstab then I reboot my machine but to my surprise it didn't boot instead black screen appeared.
I also opened /etc/fstab using VI editor but I couldnot erase my entry in /ec/fstab as it is read onlyfile.

Thanks & regards ,
Sangeeta

Boot to runlevel 1 or runlevel 3 (and login as root) to edit fstab.

Hi thanks for your reply. As I turned on my machine I get black screen showing following messages.

Giving root password ,I also tried to delete my entry in /etc/fstab using vi editor but it didn't allowed me.
Do you mean that I need to run boot loader to edit /etc/fstab.

After you get the root shell prompt, you need to remount the root filesystem read/write:Then you can use an editor to change /etc/fstab. When you exit from the shell, the system will reboot.

hi,
Thank you .I just followed you then my machine starts to reboot. Now I am able to carry my regular jobs. It's a big relief to me.
