This is gonna be first time I typed in a forum, omfg. The OS disc that you bought! Just load it into DOS mode and repair it!
Well..You're pretty much screwed then until you either find the cd, or buy a new one. Repair install won;t work without it.
for a single missing file any type of the same version shoulkd work. xp --- disc works w/ xp home and mce.

Did you try the way HydrogeN said. And yes you can buy a Windows Xp disk. Hp is the type of computer core it is built on Windows xp is the operating system And if that doesn't work, just try reformatting your pc.
