Bâshrat as per your feedback, I followed the link (Check the sticky, section #2.) and tried to make the unattended cd. I used the drivers via cd method (Pyron's method) for installing my Sony VAIO Laptop drivers. I followed the process for adding drivers to the CD and replaced the setup.ex_ file and added the others as per the guide. However, while running the setup, I get an error saying: Cannot copy setupORG.exe. I am given the option to either retry or skip the file. Even after retrying, the file does not get copied and if I skip the file and let the installation continue, after reboot I get another error saying "cannot find setup.exe" and the computer reboots. I have tried this method twice for creating the cd from scratch, however I get the same error. Although as told by you, I have made the unattened cd to install drivers via the Winnt.Sif file (OemPnPDriversPath method), I would be more interested to install the drivers via the cd. Also I would try to install windows xp and drivers through Winnt.Sif. I hope it works and the the following error would be removed: "Files that are required for Windows to run properly have been replaced by unrecognised version. To maintain system stability Windows must restore the original version of these files. Insert SP2 CDROM now." Could you possibly shed some light why the setupORG.exe is not being copied to the HDD with other files. Regards, Graveyard.
