Not as simple as telling you how to install Linux as that.
Is your hardware supported by Linux? (Should be but always nice to check it out first)
Did you download this or buy it? If you bought it they come with instructions. If you downloaded it you can get instructions from the web.
Have you ever installed Linux or played with Linux before?
Depending on the answer for the above question. If yes, Well do you want to dual boot? partition a HDD? Do you know how to configure the lilo? Is it to be a single boot?
I'm not saying you wasted your time asking the question or that Linux is so hard to use, it's easy and nice when you know how. Also fun
We need more details with your question though to help and give the best answer for you. Like do you want help installing Linux from scratch? Or are you just having some problems at some stage of the install? Hardware Specs may be needed to help solve the question.
