In Windows 7 and Windows 8, you don’t need to get third party software to burn it. Not anymore. The built-in Windows Disc Image Burner will let you burn ISOs onto disc. But not just of Windows. Of any OS.
I’m going to show you how to burn an ISO image — in this case for the purpose of creating an Ubuntu install disc.
First insert a blank CD or DVD into your optical drive.
Right click the ISO file. Click Burn Disc Image.
The Windows Disc Image Burner utility comes up. Select the drive with your blank disc, check Verify Disc After Burning. Click Burn to start the process.
Now wait while the system burns the bootable ISO to your blank disc. The amount of time it takes will vary depending on the speed of your CD / DVD drive and the amount of data being burned.
After burning, Windows will scan the disc and verify there are no corruption issues.
All done! Your CD / DVD tray will open with your disc-bootable version of Windows.
Make sure and label your discs so you don’t lose track of them.
This process is the same in both Windows 7 and 8.
Windows Disc Image Burner isn’t for just creating bootable ISO images. If you convert a DVD to ISO you can use it to burn an unprotected DVD ISO to disc, so you can watch it in most DVD players.
If you download Windows 7 via TechNet or MSDN, it comes as an ISO file that you can and should burn to disc in case of a future emergency.
