Burn a CD or DVD from an ISO file Applies to Windows 7

An ISO file, also called a disc
image, is a single file that’s a copy
of an entire data CD or DVD. When
you burn a CD or DVD from an ISO
file, the new disc has the same
folders, files, and properties as the
original disc. The most common
way to get an ISO file is to
download it from a website. For
example, you might download and
then use an ISO file to update
software on your computer.
You can burn a disc image file,
which often has either an .iso
or .img file name extension, to a
recordable CD or DVD by using
Windows Disc Image Burner.
Whether you can burn it to a
recordable CD, DVD, or Blu‑ray
Disc depends on your disc burner
and the type of discs it can burn,
the size of the disc image file, as
well as the device on which you
plan to use the disc.
1. Insert a recordable CD, DVD, or
Blu‑ray Disc into your disc burner.
2. Open Computer by clicking the
Start button , and then clicking
Computer.
3. In Windows Explorer, find the disc
image file, and then double-click
it.
4. If you have more than one disc
burner, from the Disc burner list
in Windows Disc Image Burner,
click the burner that you want to
use.
5. (Optional) If you want to verify
that the disc image was burned
correctly to the disc, select the
Verify disc after burning check
box.
If the integrity of disc image file is
critical (for example, the disc
image file contains a firmware
update), you should select this
check box.
6. Click Burn to burn the disc.
