| you can use fdisk -l in the terminal to see the partition list.
if you have the partition as /dev/hda1 or something
type fdisk /dev/hda
or if its something else like /dev/sda1 or /dev/hdc1 or anyother
type the name without the number
in fdisk as fdisk /dev/sda and so on.
then typing p will list you the same partitions
see which is the partition you want to delete and note its patition no.
type d which will ask you for partition no.enter it
enter w to write partition table.
enter q to quit
then type partprobe on the terminal to reload the partition into linux or just restart your system.
If this is too complex for you, dont try it .
Instead you can opt for GParted, a gui partition editor.
you can install it using
apt-get install gparted
PS: all these should be done as root or using sudo |
