Hi,
First, get a listing of your current partition scheme, type the following command:
# fdisk -l.
Output:
Device Boot Start End Blocks Id System
/dev/hdb1 * 1 2432 19535008+ 83 Linux
/dev/hdb2 2433 2554 979965 82 Linux swap / Solaris
/dev/hdb3 2555 6202 29302560 83 Linux
/dev/hdb4 6203 9733 28362757+ 5 Extended
/dev/hdb5 6203 9733 28362726 83 Linux
From above output I have two hard disks:
=> /dev/hda - 20 GB
=> /dev/hdb - 80 GB
Let us assume that you want to remove a partition from /dev/hdb disk. Type the following command:
# fdisk /dev/hdb
Output:
The number of cylinders for this disk is set to 9733.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)[/color]
Command (m for help):
Now type p command to list partition:
Command (m for help): p
Output:
Disk /dev/hdb: 80.0 GB, 80060424192 bytes
255 heads, 63 sectors/track, 9733 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Now let us say you want to delete /dev/hdb3 (3rd partition). Type the d command to delete a partition:
Command (m for help): d
Partition number (1-4): 3
It will prompt you for the partition number. Type 3:
Verify that partition deleted:
Command (m for help): p
Now save the changes and exit to shell prompt. Type the w command:
Command (m for help): w
Reboot the system.
Thanks
