How do I run Ubuntu from the desktop ISO image?
Solution 1:
Right click on the ISO file and, if available, look at the options under "Open with". You should see an alternative program such as "Windows Disc Image Burner" (depending on which version of Windows you are using).
Alternatively, download "ImgBurn" which is a free ISO writing application which will allow you to burn this image to disc avoiding the problematic installation of "Sonic RecordNow!".
Solution 2:
The recommended way to install Ubuntu is from a USB drive, CD, or DVD. If you have a newer computer which is capable of booting off of a USB drive, you can follow these instructions to create a bootable Ubuntu USB drive using Pen Drive Linux.
If you do not have access to a USB drive, or your computer cannot boot off of one, you can create a bootable CD or DVD, which will work on almost all computers. Follow these instructions to create a bootable CD or DVD on Windows.
