I recently installed Ubuntu on a new hard drive. I did not perform any partitions during installation. After the installation and upgrade, I tried to partition the drive in which ubuntu was installed.
File System: ext4
I am not able to create another partition from this one. Is it possible to do it or should I have to live with one BIG partition????
The option to resize this partition is greyed out.
What happens if I try to unmount this partition???
