Okay, |Root |--PRO1 |--SETUP |--XP |--PRO |PRO1.dat |other necessary files I use Win2k SP4, BartPE and XP Pro SP2 for it. When i try to make a new cd/dvd using all the files from the already working dvd, it asks me to insert 2nd installation disk in drive a: during the installation procedure; same happens when I try to make a different dvd using the files from ROOT but moving them over to an other partition. I use CDShell. Can I provide any further information that might be useful? PS: The disk00* files exist in the boot folder, but why should they change or dissapear when moving the folder? Thanks again for trying to help me, perhaps its just something ridiculous but I can't find it....
