“A laptop that runs a variant of the Linux open source operating
system such as Ubuntu, openSUSE, Fedora, Red Hat or Mandriva. While
a Linux laptop can be purchased with Linux already preinstalled, in
many cases a user will need to purchase a laptop that doesn’t have
an operating system preinstalled or a laptop with a version of the
Windows operating system and then install Linux on top of it.“In the latter case, both Windows and Linux can reside on the
same machine in what is known as a “dual-boot” scenario. PC
manufacturers that offer pre-installed Linux laptop computers range
from the well known like Dell and HP to less familiar companies
like System76, ThinkPenguin and LinPC.“See Linux and operating system terms in Webopedia, and learn
