Create an ISO image from a CD on Ubuntu
There a few good reasons to convert a CD ROM to an ISO image. With an ISO disc image, you can have an exact backup of important software, or use it to quickly install an operating system using virtualization software like VirtualBox. To create an image, simply enter this command in a terminal window:
sudo dd if=/dev/cdrom of=~/nameofimage.iso
This will save an ISO image named
nameofimage.iso in your home directory. I recently used this command to make an image so I don't have to go hunting for my Windows 7 disc so often.
