Unmount disk to delete partition

**Unix'EM** · 16-10-2009

Hello, I have an old computer with 40 GB hard disk and there are two paritions on my computer. I need to delete the second partition and create new partitions of 10 GB each, but i cannot delete the partitions it says unmount partition. Please help...

You cannot delete a partition that is mounted, you have to unmount the partition first, and when it is successfully unmounted, delete it... To unmount a partition, open terminal and type :

Code:

sudo unmount disk/partition

EG :

Code:

sudo unmount /dev/sda3

Hope this helps...

Use GParted to unmount, delete, create partitions. Its is a user friendly tool that deals with Hard disk and operations on it. To downloaded GParted open terminal and type :

Code:

sudo apt-get install gparted

Then run GParted and it will guide you...
