Cooperative Linux may also define as co Linux. It is one of the software which is used to run both Microsoft windows and the Linux kernel similarly at the same time on the same machine. The same binary format which is used in Linux is also used in Co Linux. It can be load and run an existing unchanged Linux at the same time with the host OS. Co Linux is a system that consists of a Windows kernel driver, a Linux kernel and some user space daemon programs. Co Linux is not an emulator or a virtual machine.

To download and install the co Linux we must need mainly a Winrar tool, which is used to run Co Linux. The main advantage of Co Linux is it is portability. Using Co Linux we can move root file system to another host after that we can restart.Co Linux is very quite easy to install and configure. But the main demerit is it may some crash the entire machine.
