Hello I am a new user so hello!! My setup that I have been creating for months are made via Nlite and personal scripting via batch files, I have created a unattend for the following: * Windows XP Home OEM SP3 * Windows XP Home Retail SP3 * Windows XP Home Upgrade SP3 * Windows XP Pro Corp SP3 * Windows XP Pro OEM SP3 * Windows XP Pro Retail SP3 * Windows XP Pro Upgrade SP3 * Windows XP Media Centre SP3 Now I have created them all with there seperate ISO's. With my unattend setup it installs: - All windows update to date (Slipstreamed with SP1/SP2/SP3) - .net framework packages - Office 2007 with SP1 and SP2 (unattended) - Video/Audio codecs - Zonealarm /AVG - Windows Plus! Media Edition - Registry files to correct the keyboard currency location etc... - Runs Disk Clean up - Runs Defragmentation (Note: Windows XP Media Centre was so hard to do because of that rollup 2 thing, but i by passed all that and it all works with sp3 and all updates and everything ) So all the above is processed unattended, so i put the ISO image via VMWARE or on disk on a pc , put it in , leave for for a hour or so and it does all of that on its own. So, seems really good? I havent got a problem with it , however the problem starts when I merge all editions on 1 disk, I following MagicIsos guide on creating a multiboot ( http://www.magiciso.com/tutorials/miso-create-multi-os-cd.htm ) I can get the menu up and working, when it boots when i click on a OS version it loads, then it loses all the unattend to it! It asks me to format the disk etc.... what have I done wrong or what havent I done? I have extracted the boot file from each OS ISO image, I have done the correct folder/file structure, edited the setupldr file to point to the I386 (renamed) in the CD drive also the txtseup.sif, I just dont get it! It works fine on its own ISO images but when i try do a multiboot it loses the unattend? Please can someone help?
