Why won't bootable CDs work?

[Machina]

Ah, yo guys, gh0st and Ice....
See, just because you can START the CD, and start installing Windows - it does NOT make it bootable.
Right before the acctual installation (aft eru copy the needed files, etc, etc, when the pretty screen comes up) - you will get a i386 ERROR and installation will abort...

The only way to make a working copy is to use NERO and manuall adjust all that stuff...
