Downloaded windows 7, how to burn an iso image to my cd?
Use a CD burning program, like the free and excellent ImgBurn. When you run it, select "Write Image File to Disc" and it will ask you to browse for the .iso. Note that Windows 7 is a DVD image, NOT a CD image. I hope this helps.
Burn it on a DVD, since that’s what the instructions say.
No, you will need to burn it to a DVD. You can use ImgBurn to do so.
The free Windows Server 2003 Resource Kit Tools (which are also supported on Windows XP) include
cdburn.exe, command-line DVD and CD burning programs.
If you're on windows: CDBurnerXP - fast, easy and free: http://cdburnerxp.se/download.php
On Mac: Disk Utility handles itself pretty well
On Linux: I use Brasero
You need a DVD or thumb drive.
