There are two basic ways of creating a new partition. The first is through Disk Management from within the Vista operating system itself or, alternatively, there is a way of creating a new partition using the Vista DVD.
By default Windows Vista can create 3 Primary partitions on a drive. If you create a fourth partition this will be created as a Logical or Extended partition.
To create a new partition using the Vista CD proceed as follows:
1/ Switch on your PC
2/ Quickly insert the Vista DVD into your CD/DVD-ROM drive
3/ A message will appear asking you to 'Press any key to boot from CD/DVD
4/ Press any key
5/ A black screen will now appear with a progress bar along the bottom. The legend say's 'Windows is loading files'
6/ After the files have been loaded the Language screen will appear.
7/ Select your language from the list and press Next
8/ At the Installation screen press the Install Now button
9/ The product key window will now open
10/ Type your product key number into the available box and then press OK
11/ The End user Licence Agreement now appears. You 'must' accept this to continue
12/ The next screen to appear is 'Where do you want to install Windows'
13/ At the bottom of this window you will see an option marked Drive options (Advanced), click on this option
14/ In this Window select 'unallocated space' from the list of partitions and then click New
15/ A size box will now appear under the New option
16/ Type the size of the new partition into this box (or simply accept the default), then click the Apply button
17/ The new partition will now be created.
