Creating Bootable Windows 7 DVD from Electronic Digital Distribution Files

Last week I purchased Windows 7 Professional through an online store where they let me download my copy as  an electronic digital distribution.  The downloaded files were not a single ISO image but consisted of 3 files: Win7-P-Retail-en-us-x86.exe, setup1.box, and setup2.box.  This was annoying because I had to take the files and create a bootable ISO image which can be burned onto a DVD myself.

Creating Bootable Windows 7 ISO image

1. Place the downloaded files (Win7-P-Retail-en-us-x86.exe, setup1.box, and setup2.box) in the same directory e.g C:\Win7Pro.
2. Run the Win7-P-Retail-en-us-x86.exe executable to extract and unpack the installation content.  A new directory will be created C:\Win7Pro\expandedSetup which will contain all the Windows 7 setup files.
3. Download the Oscdimg CD/DVD Premastering Utility and copy it into the directory C:\Win7Pro
4. Open the command prompt and run the following command:
   C:\Win7Pro\oscdimg.exe -bC:\Win7Pro\expandedSetup\boot\etfsboot.com -u2 -h -m -lWIN7PRO C:\Win7Pro\expandedSetup\ C:\Win7Pro\Win7Pro.iso

   

When the command has finished, a bootable Windows 7 UDF format ISO image (Win7Pro.iso) will be created in the directory C:\Win7Pro directory which can be burned into a DVD.  The ISO image can also be used to create a bootable USB drive with the Windows 7 USB/DVD Download Tool.
