Some of us might have encountered files ending with the extension .iso.This simply means it's a disc image file and needs to be burnt to a disc or (you extract the files in them using Win-image or Winrar).
You can burn a disc image from the
command prompt interface by passing the proper parameters.
To start burning a CD or DVD ISO file immediately from command prompt, simply type in:
isoburn /q drive:\file.iso
For example: isoburn /q c:\en_windows_7_ultimate_x64_dvd_X15-65922.iso (Note for command prompt)
Ensure the disc you want to write to has enough or more storage size than the size of the file you want to burn.
Alternatively,Windows 7 and 8 includes a free image burning utility called the
Windows Disc Image Burner that allows you to quickly write CD and DVD
As shown in the image, you can pass only the ISO file location and click the Burn button within the utility.
