[italian] Non credo proprio... [/italian] No way, not really welcome on international fora... Hmmm, check THOROUGHFULLY the FAQ's: http://www.msfn.org/board/index.php?showtopic=116766 we are sure that it is NOT FAQ #8, but what about the others? Where does the source come from? Is it OEM/nlited/modified? Best test would be to FORGET (for the moment) about USBmultiboot and try WinsetupfromUSB: http://www.msfn.org/board/index.php?showtopic=120444 and see if the result is the same.... jaclaz the source is a winxp sp2 , i don't know if is it OEM/nlited/modified , how i can see that? i go to view the faq's , tomorrow i try the winsetupfromUSB thx for all
