I have one operating system installed on my pc
I want to uninstall it and install linux
How should I start?
I would recommend Ubuntu also. It is the best of the "beginner friendly" distros in my opinion.
If you are currently using Windows, you do not have to remove Windows to install linux. You can set up a dual boot system. This will allow you to choose whether you want to boot linux or Windows when you start your computer. I have Ubuntu, Slackware, and Windows XP on the computer I am using now.
Here are 2 great websites for getting started with Ubuntu, and setting it up as a dual boot system:
Of course, you can also remove Windows if you want to and use only linux. It is your choice. Linux is all about freedom of choice.
