13.04 - How can I create one more partition?

• sda1 -> Windows XP


• sda2 -> Windows 7


• sda3 -> Data Partition

I have created 4 primary partitions, I have 7xx GB left, how can I create one more partition?

To most "logical" thing you can do is:

1. Expand your 4th and last Primary Partition (sda4) which is an
   Extended Partition (which merely serves as a container for Logical Partitions) so as to include the unallocated space at the end.


2. Then create another Logical Partition (or more) at the end of sda4.

However, you can only do this if and when the Extended Partition is (i.e. sda5 and sda6 are) not mounted.

Therefore, I would suggest you use an Ubuntu (or any other Linux, e.g. Parted Magic) Live CD/DVD/USB to boot your computer for this purpose.
