hi every one.... I am a "BIG" fan of MSFN. I just want to know that can we install windows xp "UNATTENDLY" without having Cd-rom and floppy. I mean just by using the Previously Backuped I386 folder and some initial booting device like Usb Memory..... i am aware of all the complications of windows xp unattended installation i have been searching from the last two months but did not find any direct artical for this situation.......... Plz Let me know !
