Someone could explain the structure of an esd file which contains multiple volume images?

Thanks

Hello all. Just to let everyone know. I decided to just go ahead and upgrade my 8.1 Pro to 10 yesterday. All went well and it, of course, it activated.

Now to make an ISO to to fresh install > Does/would the new Media Creation Tool Performed within the OS create the same ISO as would the ESDtoISO tool?

Media creation creates the setup media with a single index, compressed install.esd
Other then that, and unless you actually need an install.wim
there is no difference between the method used to create ISO

... if you select to create a USB install media. Selecting the ISO alternative creates a traditional install media with install.wim instead of install.esd.

Thanks for responding, gents. :)

So what you are saying, Kari, is that Media Creation Tool only uses a compressed ESD only when creating a USB ISO, correct?

The way I understand it is that ESD has a far more efficient compression ratio than WIM, which is old compression technology. Yes?

If so, then the Media Creation Tool uses the ESD file to make a fresh install ISO when made from within the upgraded OS as I just performed from 8.1 Pro to 10 Pro.

If that all be true, will it install everything > My docs, pics, favorites, Win32 programs, Store apps, and the likes? Or is there a "Save everything" option when fresh installing using this ISO starting from within the OS one wants to fresh install?

This is only a small, basically meaningless difference. In fact, both the USB and ISO created with Media Creation Tool use the compressed ESD format but if you select to create ISO instead of USB, the file extension used is WIM instead of ESD.

Both files, install.esd on USB media and install.wim on ISO image are exactly the same, only difference being the file extension.

Whatever media you use to install, USB or ISO, the installed Windows is exactly the same.

Thanks for your thorough and expedient reply, Kari. Much appreciated. :)

In short, to do this, I should run the following commands

Code:

dism.exe /Apply-Image /ImageFile:"esd_File_Path>\install.esd" /Index:<Index_Number> /ApplyDir:"<Temp_Dir>"
rmdir /s /q <Temp_Dir>
dism /Quiet /Capture-Image /ImageFile:<Capture_Wim_Dir>\install.wim /CaptureDir:<Temp_Dir> /Name:"container" /Compress:max /CheckIntegrity
dism /Export-Image /SourceImageFile:<Capture_Wim_Dir>\install.wim /SourceIndex:1 /DestinationImageFile:<Windows_Files>\install.wim /compress:recovery /CheckIntegrity
del <Capture_Wim_Dir>\install.wim

for each volume image of Windows that I would. At this point, I should have the install.wim. Right?

Now, I can not understand how can I get the other files which make the DVD.

Someone could help me?

Thanks

Note

I have today updated the tool used in tutorial with current, valid encryption keys (version 6.7 of the script). It now works with every build up to Build 10525 released today, letting you to create a bootable ISO image from the install.esd file downloaded from Windows Update, to be used as mounted virtual drive for in-place upgrade or when burned to DVD or USB Flash Drive for a clean install.
