Firstly let me say thanks for the tool..! I have figured out all the options and created, packed (took 80mins using 6.21) Used poweriso to create an iso, removing the autounattend.xml before doing so and then tested the iso install using VMware V7. Now the install goes well, however when i attached a USB flash drive and attempt to install using the autounattend.xml it stalls after 1st reboot at the completing install phase, looks to be about 70% done. My question is what in the autounattend.xml sample that Max provided, would stall the install... cos i'm stuck.. ? Another question, icreated a multiinstall XP install based on the unattended sif file leaving out computer, Prod key and user name so that they could be added during install to personalise the install (repair shop) can the autounnattend be used to do the same thing or must the fields be filled in otherwise the xml answer file fails.. ?
