No. Any machine that is capable of running Windows 7 is equally capable of running Linux; thus virtually every computer is "Linux ready." Depending on your specific needs, Linux can be run on far less powerful and cheaper hardware than Windows 7 can.
If you would like to install it ON TOP of Windows: Install a virtual machine program (ex. Virtualbox, VMware) Install Linux inside of virtual machine Install it along side (or overwrite) Windows: Reboot computer with Linux install CD/DVD in the disk drive and follow the instructions.
Windows and Linux use device letters to identify each storage device on a computer.
Mac, Windows, and Linux.

instead of windows you can have linux or mac. they are different, but you will know whats best for you when you try them, linux is free to download.but you need an operating system (windows, mac, linux or any other OS) for the computer to work
Yes. There is a Linux port of Virtualbox and it runs Windows as well as any version of VB.
You can't. You could run it on a Linux virtual machine inside windows though.
A Linux, Windows, or a Macintosh.
If by computer systems you mean operating systems, then: 1) Windows 2) Macintosh 3) Linux
with Linux you can run in almost any machine, but you need a minimal requirements and knowledge about the machine a example people cant run Linux in some cell phone has the power to run Linux but can´t because it is hard to get the information about the processor
There are no wild computer viruses that affect Linux. Oh wait, there was RST.b. If you need to, you can run certain windows viruses under Linux with wine.
Yes, you can. It's called dualbooting. I guess with Linux you mean a Linux Distribution like Ubuntu? Check the related link if you want to know how.
