How do I resize root partition
I need to resize root as there is not enough space left in the partition. At present I am not able to install new package nor update ubuntu. I tried sudo apt-get clean and emptying trash but it does not make significant space.
I have dual boot system (windows-7 and Ubuntu 14.04 LTS) with two Internal hard drive. Where Windows is installed in /dev/sda and Ubuntu is installed in /dev/sdb. I tried to resize root using Gparted but it does not allow. Please let me know the steps of using Gparted for resizing root. I want to transfer space from "/home" to "/".
df -h

Thank you
You do not have /root partition. You probably want to increase size of your / partition.
You will have to boot from liveCD to resize these partitions.
It must be safe, because you have a separate /boot partition, otherwise /etc/fstab may need to be updated with new UUID and/or grub reinstalled.
In your case you need to shrink your /home, which is /dev/sdb7, then move your swap partition right, then extend your / (/dev/sdb5) right.
You can do it with a mouse. Just drag partition's sides left or right.
This may take a lot of time.
