Creating an .iso file from a .wim file

To create a bootable media by using a .wim file, you need to convert it to an .iso file first.

To create a PE image (.iso file) from the resulting .wim file:

1. Depending on your version of Windows AIK or Windows ADK, do one of the following:
   • In the Start menu, click Microsoft Windows AIK, right-click Windows PE Tools Command Prompt, and then select Run as administrator.
   • In the Start menu, click Microsoft Windows AIK, right-click Deployment Tools Command Prompt, and then select Run as administrator.
   • In the Start menu, click Windows Kits, click Windows ADK, right-click Deployment and Imaging Tools Environment, and then select Run as administrator.
2. Run the Copype.cmd script to create a folder with Windows PE files. For example, from a command prompt, type:

   copype amd64 C:\winpe_x64

   To create x86 WinPE, type x86 instead of amd64.

3. Replace the default boot.wim file in your Windows PE folder with the newly created .wim file (for example, AcronisBootablePEMedia.wim). If the AcronisBootablePEMedia.wim file is located on c:\, then:

   For WinPE 3.0, type:

   copy c:\AcronisBootablePEMedia.wim c:\winpe_x64\ISO\sources\boot.wim

   For WinPE 4.0 or WinPE 5.0, type:

   copy "c:\AcronisBootablePEMedia.wim" c:\winpe_x64\media\sources\boot.wim

4. Use the Oscdimg tool. To create an .iso file, type:

   oscdimg -n –bc:\winpe_x64\etfsboot.com c:\winpe_x64\ISO c:\winpe_x64\winpe_x64.iso

   Alternatively, to make the media bootable on both BIOS and UEFI computers, type:

   oscdimg -m -o -u2 -udfver102 -bootdata:2#p0,e,bc:\winpe_x64\etfsboot.com#pEF,e,bc:\winpe_x64\efisys.bin c:\winpe_x64\ISO c:\winpe_x64\winpe_x64.iso

5. Burn the .iso file to a CD by using a third-party tool, and you will have a bootable Windows PE disc with Acronis True Image.
