About the problem: No root file system is defined

To better understand the problem, we will first briefly know the root file system, then the causes of this problem.

What is the root file system?

Basically, the root file system is the file system which is placed on the same partition on which the root directory is located. This is the file system that all other file systems are attached to when starting or starting the system. To find out more, a partition is a theoretically independent section of a hard disk drive (HDD). A file system is a directory hierarchy which are used to organize the files on a computer system. He is also known as a directory tree. When you are on Linux and other Unix-like operating systems, the directories start with root directory, which also contains a series of subdirectories. Each subdirectory also contains other subdirectories. A variation of this definition is the component of any directory tree on a single partition or disk.

How does the root file system work?

Only the root file system is available when a system is started in single user mode. Single-user mode is a method of starting a damaged system with very limited capabilities. repairs can be done for her. Once repairs are complete, other file systems on different partitions can be mounted on the root file system to restore full functionality. The directories on which they are mounted are called mounting points. The root file system should generally be small because it contains critical files. A small, rarely modified file system is less vulnerable to corruption. A corrupted root file system will usually indicate that the system is becoming not bootable of Hard disk, and must be started by special options like Boot disk.

What is the cause of the problem with the rootless file system?

You have not learned enough about the root file system and its tributaries. We will now go further to know the cause of this problem. This error usually appears during installation Ubuntu or other Linux distributions. Most of the users who suffered from this error reported that they were trying to install Ubuntu. You should now ask yourself why this error message appears specifically when you try to install Ubuntu. I will erase your request.

There is 3 major causes of this problem. They are as follows:

1. You forgot to create a valid account Linux Partition.
2. You are unwittingly trying to use a Windows partition (FAT or FAT32) install Ubuntu, but this requires a Linux partition.
3. A Linux partition exists but you have NOT defined root partition ("/"), and you must set it to install Ubuntu or other Linux distributions.

You must have caught your fault now. This error usually occurs with Ubuntu because people do not have much information about Linux and its partitions. We will now move to the solutions of this problem.
