I need to Perform a Repair Installation of XP but every discussion of how to do this that I have seen requires that one boots from an XP CD. I don't have an XP CD and have never seen one. I must have set up and configured a dozen XP boxes but I have never seen an XP CD, the machines have always come with the OS installed and no CD. what's a person to do? Is there anyway to do a repair installation without the CD? I believe there is an equivalent of an installation disk on a separate partition of the machine but have no idea of how to access it. It is an HP Pavilion, btw. Any ideas will be gladly and humbly appreciated.
