I like to capture my thick/hybrid WIM files with SCCM capture ISOs. The big problem with this is that MDT doesn’t like WIM files with multiple indexes. The symptom is that MDT appears to import the WIM, but NO OSes are added to the Deployment Workbench. To fix this you must delete the 1st index from the WIM before performing the import into MDT.
WIM with 2 indexes:
Command to delete the 1st index:
dism /delete-image /imagefile:7x64Pro-2016Jul20.wim /index:1
/BG
You are my hero! Thank you thank you thank you!!!!!
