You are Welcome!
If you still want to dual boot Win's XP with Ubuntu Linux you can.
You just need to shrink your Win's XP partition first; than install Ubuntu--
During the installation you will be prompted by a 'partition manager'
Make sure you write down your Win's partitions so you know what they look like when the Ubuntu partition manager shows you them so you don't change them. Use the free space to create your partitions for Ubuntu.
If that's hard to understand just right click on 'Control Panel"
Than right click on 'Disk Management' than shrink your Windows partition.
Have a good weekend!
