I need some help to create a recovery image or recovery partition in Linux operating system. I have a old laptop that works on ubuntu. Now we do not have any cd or dvd that we received with it. I have a windows laptop on the other hand which has a factory partition. In-case of error we can restore that very easily. The story in Linux is very different. There is nothing inside. Is there a way I can create a disc or partition for future purpose. I need help but not able to locate any stuff related to that.
