Thanks, but i know to do it. I need install windows xp on msdos because i want include diferents operative systems in one CD o DVD. I have done one thing similar to Hiren's bootcd ( bootcd with many applications included ) then i cannot use the boot of windows xp CD, i have to use msdos installation. I already have a unattende installation of windows 98 and i have not problems. In windows XP i can automatize the second part of installation and the third part (GUI installation). Part One i Boot from bootcd (cdrom drivers are loaded) and i execute the followinb batch file. @echo off smartdrv.exe winnt /s:%cdrom%:\i386 /u:%cdrom%:\unattended.txt (The files are copied to hard disk and i have press enter to continue (REAL PROBLEM) Part Two --------> Press F2 to.... , Press F6 to install RAID...,.... Files are copied to hard disk from hard disk. Here the restart is unattended. Part thee---------> GUI installation. Fully unttended. The problem is than i only can automatize the part two and three, althoug the part one, at end of the files copy, i have press "enter" to answer what i am prompted ("The part based on msdos has finished, press enter to continue installation [ NOT UNATTENDED ] I think that it is not posible, but perhaps i could be surprised by somebody . I hope that you know what i really want to do. Thanks you very mucy.
