This is how my hd's look at the moment:
Obviously the first partition on 'Disk 0' is Windows Vista.
The unallocated space on 'Disk 1' is the partition I've made to hopefully install Windows XP.
I have never done this before and do not know where to start. Saying that, if there are any risks involved in doing this I would be more than grateful becoming aware of them.
I have a Windows XP Professional disk from a previous computer, but not a Vista disk as my laptop came with it already on.
I am creating a partition solely to be able to use a program which is not compatible with Vista.
Thank you for any help.
