A "Ghost" version of Windows XP is not a standard installation disk. Instead, it is a compressed "image" created using Norton Ghost (often version 11.x) that contains a pre-installed instance of Windows.
The phrase “self contained” meant the ISO didn’t just boot Ghost; it contained a compressed WINXP.GHO file inside the ISO itself. You didn’t need a second CD. One disc held both the cloning environment and the operating system image. Windows XP Ghost -self contained bootable iso- - Xander
