First of all thank you guys for your help... I've found out how to skip those two steps In the winnt.sif I've inserted: [Data] AutomaticUpdates = Yes (it skips the screen to configure the automatic updates) [Display] BitsPerPel = 32 XResolution = 1024 YResolution = 768 VRefresh = 75 AutoConfirm = 1 (it skips the question to fix the resolution at first boot after the installation) But I have another problem now!!!!! It doesn't change the resolution to 1024x768... and I have 640x480!!!! Any help on that? Thank you!!!!!
