Windows 7: How to convert a windows WIM file to a ISO file

How to convert a windows WIM file to a ISO file

I am trying to find a way to take a WIM file from WDS, and convert it to an ISO image, so that I can use the ISO to install into VMware machines. I've read the many posts on how to convert a discover.wim to an ISO, but this doesn't work for what I'm trying to do.

Any suggestions on how to get a captured WIM converted to an ISO?

Thanks,
Pakka77

what OS is in the WIM? It might be easier to redownload as an iso image.

You might want to try using Windows AIK . oscdimg will allow you to create an iso from an .wim file. It will gather all the files and put it into an iso. I know it works cause that is what I do to install and test on vmware.

Command: oscdimg.exe –bC:\expandedSetup\boot\etfsboot.com –u2 –h -m -lWIN_EN_DVD C:\expandedSetup\ C:\Windows 7.iso

Most of the Images are windows 7, but they have a bunch of 3rd party applications added to them, that we are trying to add into the eventual ISO. So when the new VM is made it comes with the OS and 5 to 10 standard applications like (Office, etc.) already installed. Cuts way back on the build time if we can shortcut it a bit by taking the WIM that has that information in it and make it an ISO for new VMs.

Yes that will create the iso from the wim file " install.wim " it will take all the files needed to create the iso for you. Then you just need to burn it onto a disc. Or what you could do is download UltraIso . Add the files you want and save it as an iso. I do that as well.

The -m option doesn't appear to be working It is also not listed in the /? file for OSCDIMG when I try and convert my 6.6gb image it comes back and says its larger then 4GB and errors out. Any suggestions around that? Is it possible that ADK is causing issues with the AIK command?

Well I uninstalled Win8 ADK, and ran a Repair of AIK, for no change. The -m function does not appear to be part of the oscdimg.exe command structure any longer. Which appears to limit my ISO image size to 4GB. Does anyone have any additional suggestions? Vistaking's suggestion would work except for the size issue, as I was able to use it for a smaller ISO.



Thanks,

In addition to VistaKing's excellent suggestion, have you looked at SysPrepping the setup install before imaging and then just applying the image which takes about 20 minutes? SysPrep to move HD to another computer

Looking at this link Oscdimg Command-Line Options it does state that there is a -m switch which Ignores the maximum size limit of an image. Try this switch " -maxsize:4096 " without the " -m " switch.

VistaKing had the answer to my question, save one item I didn't think to provide. I didn't have the -m option and was unable to get past the 4GB size limit, because I was using AIK version 1, Not the most current version... I'm now able to break the Limit with no problems.

Thanks again, for all the help.
