You can boot Windows from CD using BartPE, but you have to include all the drivers needed by your computer, all what is needed by your applications and the applications itself. Probably you will need to edit your Windows installation CD setup file (is a text file). Not all Windows CD work with BartPE, some are crappy.

The problem of booting Windows from CD is that you cannot install anything because Windows is on a CD and you cannot write to the registry dat files, the document and settings folder and program files folder, all are read only in the CD. You are only able to install programs that have all contained in a zip file and don't use the registry or use for nothing important.

Stupidity also evolves!
