Re: Converting WIM to ISO

[Casey R DeBord <debordcr () UNK EDU>]

I think I understand what you are doing wrong.  You must boot into WinPE 
environment.  You can't make the WIM file itself bootable the same way you 
can make a WinPE image bootable.  You'll have to boot into WinPE and then 
call upon that wim file from within winPE.

What I would do is mount the WinPE image and move the universitybase.wim 
file into the file structure of the winpe wim file, or boot.wim.  Then 
when you load into WinPE, the unversitybase.wim file will be accessible in 
the virtual file structure it creates.  I did this with some lab machines 
that I had student workers deploy.  This way they didn't need to 
authenticate to the network to deploy it for me.    I then just created a 
batch file that applied the image by typing a simple "startdeploy" command 
or something similar.  They could then walk away and retrieve the dvd 
after the machine had restarted.  But again, your limited to the filesize 
of your media.

If that still doesn't make much sense I'd do some more checking on 
modifying or customizing your WinPE image.  Essentially you're just 
putting a wim inside of a wim so you can access the wim after you've 
booted from the first wim.  : )

Hope this helps(and makes sense!)

I can also send you the rest of that guide I wrote if you'd like.  Just 
let me know.

Basically a discover image is used to boot a machine into windows PE 
mode.  What I want to do is create an ISO with an image I created. The 
image is in WIM format. I want to convert this 4 gig customized image into 
I ISO so I can put it on a DVD and carry it out to remote locations and 
install my customized image from the DVD. Currently my customized image is 
in WIM format on the deployment server. How do I covernt that WIM to an 
ISO?   I followed the steps below (you had sames steps I tried) but the 
ISO wont boot. I get the following error….
 
FILE: \windows\system32\boot\winload.exe
 
Status: 0xc0000001
 
Info: The selected entry could not be loaded because the applications is 
missing or corrupt
 
 
These are the steps I took to create this ISO that doesn’t work. 
 
1.       Installed Windows 7 on a machine and customized it
2.       Sysprep /oobe /generalize /reboot
3.       PXE boot to Capture image and pushed it to the deployment server
4.       Tested the deployment process with the image and it works great 
deploying over the network
5.       Log into the deployment server and exported the image to the 
c:\univeristybase.wim
6.       Opened a Deployment tools command prompt and ran the following:
a.       Cd C:\Program Files\Windows AIK\Tools\PETools
b.      CopyPE x86 C:\Winpe
c.       Copy /y c:\universitybase.wim c:\Winpe\ISO\Sources
d.      Cd C:\Program Files\Windows AIK\Tools\PETools
e.      Oscdimg –n -m -bc:\winpe\ISO\boot\etfsboot.com c:\winpe\ISO 
c:\universitybase.iso
 
 
When I try and boot from universitybase.iso I get  the following error:
 
FILE: \windows\system32\boot\winload.exe
 
Status: 0xc0000001
 
Info: The selected entry could not be loaded because the applications is 
missing or corrupt

Nathan, 

I'm not sure what you mean with "Discover" and "captured", sorry If I'm 
totally off base.   I've created bootable winPE images for a cd and a 
thumbdrive if that is what you are asking.  If the image is small enough, 
you can also include that image onto the same cd/dvd or thumbdrive without 
"discovering" anything over a network connection. 

Here is an excerpt I wrote for my Technology Coordinators here on campus. 
Hopefully it will help you: 
While you were in c:\winpe you might have also noticed another folder 
named “ISO”. This is where we can make that WIM file into something we can 
use. Inside the c:\winpe\iso folder is a file called boot.wim. Rename it 
to boot.old and move it out of there. This boot.wim file is a backup of 
the default WinPE image we just edited. Now, copy the winpe.wim file from 
c:\winpe into c:\winpe\iso and rename it to boot.wim.

Now we can use our iso creating tool to make use of edited boot.wim file.

Oscdimg –n –h –bc:\winpe\etfsboot.com c:\winpe\iso c:\winpe\winpe.iso

This command tells etfsboot.com to find the boot.wim file and create an 
iso out of it. The –n allows for longer filenames, the –h allows it to see 
hidden files, and the –b makes it bootable. After this process completes, 
you’ll have a bootable iso file named winpe.iso. Burn this image to CD to 
make a bootable WinPE disc.

I have taken it a step further and placed the contents of that iso onto a 
thumbdrive to allow me to quickly edit the contents without being forced 
to burn cd’s. The final ISO will be about 200mb. 

If you're ask about a live os where you can simply boot into the OS, I'm 
not sure that is possible.  At least I haven't done it.

We are using Windows Deployment Server to deploy base images across 
campus.  I some cases I need to have the base image installed on devices 
not directly connected to our network.  I would like to take this base 
image and convert it into an ISO. I am having a little trouble figuring 
out how to do this. 
  
1.       Basically I need to convert a .WIM capture image to a bootable 
.ISO 
  
I some documentation at Microsoft using PETools in the AIK; however, it 
appears to be limited to creating ISO’s of “Discover” images not 
“captured” images. I tried to use this documentation to create my ISO of 
the captured image but it doesn’t work. 
  
I’m reaching out for some help, if anybody has some information on how to 
accomplish this task, I would be grateful. 
  
V/R, 
  
GIBBY
