Trying to reformat an old latitude laptop to use at my home.  Latitude D610

Gone through reformat until says DO NOT PRESS ANY KEY FROM THIS POINT

I have reformated other computers so I am perplexed as to why I cannot get this one to reformat; although, I have never reformated a laptop before

When the process gets to installing windows, it states that the file is corrupted.  This is the disc that came with the latitude

xp home edition service pack 2

Now I do not even have a computer that will work at all

I really need some advice.....
