Hello, I want to change my laptop to linksys.
And if you mean Linux, what distribution? Theres quite a few out there, Ubuntu being one of the most popular ones.
If you've never used Linux before, and/or want both instead:http://lifehacker.com/5403100/dual+boot-windows-7-and-ubuntu-in-perfect-harmony
But what Windows OS do you have? just type in dual boot ubuntu and <insert windows version here> into google there are amples amount of guides out there.
