MDT 8450 will not split WIM to support UEFI FAT32. I have used a third party tool to split the WIM but cannot get the MDT deployment wizard to see the new SWM files. I have changed the Operatingsystems.xml, LTIApply.wsf and the Unattend.xml files by changing the .wim extension to the .swm file extension.
What else do I need to change or is all the posting I have read is in correct or the .swm file extension is not supported.
Your are also missing a selection for MDT 8540 and earlier versions. WHY????
