Hello together first let me thank myselfidem for this great thread. it helped me alot creating my autounattend.xml. I'm having two last issues, i can't resolve: I have an x86/x64 AIO wimfile, at the start of the setup, i'm asked, which os i like to install, but whatever i chose, setup picks always the diskconfiguration from x86. :/ Everything else is working fine. depending on my choice the correct os is installed. the 2nd issue is, that setup says, that the partition could not be prepared, after selecting the drive to install windows to. (i'm not sure, if setup already should ask me, on which disk i like to install windows - the option is set to "onError".) After clicking ok (the only available button) on the messagebox, setup restarts the system and the partitions are created as i want them to. -.- My autounattend.xml is attached to this post i got one more question: is it possible to tell setup to use D: for the windows-swap file and E: for programs? at the moment i'm changing these settings step by step after setup completes, but it would be great to implement those settings directly into the setup, so that the windows-programs (and features) are directly installed to that drive. thanks so far for reading! Kind regards BaBa Autounattend.xml
