Hi I'm trying to create a reverse integration windows 7 professional disc with SP1, ie9 and .net 4. I have 2 retail versions of windows 7 home premium. I am using this disc to install and then ctrl+ shift + f3, install the updates, run dism, reset to system oobe, I use : imagex /compress maximum /flags BUSINESS /capture E:\ “C:\Win7\SP1\sources\install.wim” “Professional x64 SP1” I made a mistake in using my normal /flags HomePremium on the first disc. I create a .iso with oscdimg, burn it, it works fine and boots into the windows setup program, but then says I have no image to install. I thought the problem could have been in Autounattend.xml as I still had : <cpi:offlineImage cpi:source="wim:/sources/install.wim#Windows 7 Home Premium" xmlns:cpi="urn:schemas-microsoft-com:cpi" /> but I changed it to Professional but made no difference (isn't it just an internal label?) (does it need to be Professional x64 SP1? as thats what I wrote in imagex) I just remembered my laptop did come with a professional disc so I could use that, but I'm curious as to why it doesn't work with a home premium disc, it should contain every version of windows 7 shouldn't it? Regards Mike
