 The problem is that the D: drive doesn't have an operating system and doesn't have an OS boot loader, so you can't boot from it. You could run the XP install program from the D: drive, but I think (someone catch me on this if I'm wrong) that would simply overwrite/upgrade the existing 0000 installation, stil leaving you with a garbaged installation--further confused and complicated by being upgraded. A fresh, from-scratch install of an OS has to be done from some boot medium. Which leads me to ask, how did the 0000 get installed on the laptop in the first place? This one's a toughie.
