Okay so I've got my customized boot.wim, directory structure correct, made sure everything is x86, and I'm using the command line  oscdimg -n -lWINPE_EN_DVD -bc:\winpe_x86\etfsboot.com c:\winpe_x86\ISO c:\winpe_x86\winpe_x86.iso which completes successfully but upon trying to boot with the ISO (wasted two discs so far before deciding to virtualize it): CDBOOT: Couldn't find BOOTMGR.  Scouring the internet, I could not find any fixes.  Anyone run into this?  Using the latest ADK.

Hi,

Referring to the article below, you may need to remove lWINPE_EN_DVD in you command for test.
