Whatever you say against Ubuntu, you can’t just make it less popular. It is the most popular Linux distribution. Many companies rely on this distribution. I personally use it on my laptop and in my servers. Normally people use windows, and when it comes to Linux it becomes a whole other matter. If someone use Ubuntu but later he wanted to install install latest windows or old alongside Ubuntu, he may face problem as loosing Ubuntu. That is what i am gong to explain “Ubuntu Recover Procedure”.
