For many people who ordered Windows 7 through online store such as Digital River, the download of Windows 7 ESD installation files is not in a single ISO image format, but as Electronic Software Distribution (ESD) files. Also, if you’re a student who has taken advantage of the crazy upgrade deal from win741.com but instead of ready-to-install ISO of Windows 7, Digital River sent you ESD files. It’s very easy to turn them into an installable ISO. Just follow this quick guide to get Windows 7 bootable ISO image file, which can be burned to a DVD disk for a bootable Windows 7 DVD disc.
- First, make sure that all your downloaded Windows 7 files (the
setup2.box) are in the same folder.
- Then, right-click on each of these files, select Properties, and click on Unblock button to prevent the files from unable to be accessed during the process. Click on OK when done.
- Now, run the
.exeexecutable as an administrator. It will then start to unpack all the files and will create a new folder called
expandedSetup. This folder now has all the necessary files needed to install Windows 7. Exit from Install Windows wizard dialog.
- Now, move the
oscdimg.zip. Extract oscdimg.exe from the downloaded
oscdimg.exeis included in Windows Automated Installation Kit (AIK) as part of WinPE. So if you have that installed, there is no need to download the file again.
- Open an elevated command prompt as an administrator. In Vista you do this by typing
cmdinto your Start Menu and hitting [
ctrl] + [shift] + [enter]. In XP, just type
cmdinto the Run dialogue ([
Windows Key] + [R]or from your Start Menu). Run the following command:
oscdimg.exe —bC:expandedSetupbootetfsboot.com —u2 —h -m -lWIN_EN_DVD C:expandedSetup C:Windows7.isoAbove command assumes that
expandedSetupfolder is located at
C:root directory. If it's not, change so. The
-llabelnamespecify volume label, which can be changed, so do the output ISO file. Also remember that if the path has space, use quotation mark (") to enclose the full path.
- A bootable Windows 7 DVD ISO image in UDF format will be created as
C:or any folder you specified above. Burn the newly created ISO with a CD/DVD burning software such as Nero, ImgBurn, CDBurnerXP, orInfraRecorder In Windows 7, you may burn the ISO image directly from Windows 7 Explorer without third-party software by just right-clicking on the ISO file and selecting burn image. You can also use the ISO image to install Windows 7 using a USB Flash Drive.
