Ubuntu – Creating a new partition by resizing /dev/sda1


I have the partitions in my computer(11.10) as follows.

  • /dev/sda1 mountpoint-root(/) flags-boot 148GB
  • /dev/sda2 1GB
  • /dev/sda5 1GB

I have 70GB free space on /dev/sda1. I want to create a 10GB partition here to keep my documents because I'm planning to install 12.04.

When I try to do it with GParted Partition Utility it doesn't let me unmount /dev/sda1 in order to resize it and create a new partition.

Please give me suggestion on what to do.

  • GParted doesn't let you unmount the /dev/sda1 partition because Ubuntu is running on /dev/sda1. You can download GParted LiveCD from http://downloads.sourceforge.net/gparted/gparted-live-0.18.0-1-i486.iso . Burn it to a CD and boot with it. Now you can resize any partitions because every one of them is unmounted. Hope this helps :)
