Hello members

Can any one explain to me a step by step guide on how to mount root directory in r/w mode using a live cd.
I would like to use my root directory in a r/w mode but i do not know how to achieve that by using a bootable live CD…

Thank you

Hi

By using the below command you can remount your filesystem

#mount -o remount,rw /

if you want to troubleshoot your linux machine using live cd then follow the below link and get rid of grubinstall

Enter in to rescue environment by typing linux rescue at the installation boot prompt. 3). Mount the root partition. #chroot /mnt/sysimage 4). Reinstall the GRUB boot loader, where /dev/sda is the boot partition. #/sbin/grub-install /dev/sda #grub2-install --force /dev/sda Reboot the system.
