Question: I am interested in using Ubuntu for the fist time, so I went to the Ubuntu download page (<https://www.ubuntu.com/download/desktop>), to get the download file. When the file downloaded he file, it appeared in WinRAR, so I cannot burn the file to a DVD. Can anybody point me in the right direction as to how to burn this file to a DVD when the file appears as a WinRAR file? Any help would be great appreciated. Thanks :)

Answer: 
It's not actually a RAR file, it's just that WinRAR wants to open ISOs.

**This happens when both of these two conditions are true:**

1. Windows is configured to *Hide extensions for known file types*, which is the default.

2. WinRAR is installed, and configured to open ISO images.

Open WinRAR, and Click `Options > Settings > Integration` untick the ISO box, as shown above.

**Next,**

Right-click on the downloaded file, and in the context menu go `Open With > Windows Disc Image Burner.`

Insert a blank DVD, choose to verify the image after burning, and hit burn.

Done! :)
Try: do right click on downloaded iso, open with appropriate cd burner app 

or 

You can do that from pendrive too , download rufus portable app from [rufus.akeo.ie](http://rufus.akeo.ie) , attach pendrive a, open this app and select your downloaded iso file.
