As long as you have installed Windows first, Linux can be installed on any free space you have within your hard disk.
What do you mean by Linux 'letting you do everything you want to do'?
Linux is capable of doing 95% of what Microsoft Windows is capable of doing as a home computer system.
However, Linux is capable of doing 100% of what Microsoft Windows can do as a business desktop.
The 5% that Linux lacks when compared to Windows is that of superior graphics enhancement programs (mainly used in Gaming); however, they have special Codec's that can be installed to solve this problem.
Linux is enjoying a favorable press for the most part. This comes from the fact that Linux has proven to be tremendously stable and versatile operating system. When it is used, in companies or home, it almost never shuts down or crashes! Thus considered to be very desirable for many people throughout the world.
As more and more people realize this fact, they start switching to Linux
