As it seems, you have not much experience in the boot topic of linux, it can became more difficult for you as it is. I dont know how much you have done with linux already.
You have to say what distribution you want to try. The boot process can be slightly different from distro to distro. As this is not the correct Linux forum for booting other than Plop Linux, I will give you just a few instructions. When you want to have it detailed, you have to post in the forum for the Linux you want to use or investigate by yourself. Alright?
