We would learn here how to completely uninstall any Linux OS from PC through Windows.

This is a procedure that envolves to steps->

(i) Delete Linux Partition
(ii) Remove Linux OS from EFI System Partition

You must be thinking what is EFI System Partition?
The EFI system partition (ESP) is a partition on a storage device that is used by computers adhering to the Unified Extensible Firmware Interface (UEFI). When a computer is booted, UEFI firmware loads files stored on the ESP to start installed operating systems either windows or Linux(ubuntu/fedora/mint).

Let’s get started with the uninstallation procedure->

(i) Log on to Windows OS in Admin mode.
(ii) On the left-corner windows icon right click.
(iii) Here you will see options like

(iv) Open Disk Management
(v) Delete the Partition which does not have a letter (like (C:)) or is not a NTFS partition and is greater than 1GB.
(vi) Now you have successfully completed the first Step.
(vii) Ubuntu/Fedora(Linux OS) is deleted but on restarting your pc you will still see the grub option so we need to uninstall Linux OS from EFI System Partition too.
(viii) Now open the Command Prompt (Admin) ( shown in the options image above ).
(ix) Follow these commands->
Note the line after ‘#’ is just to explain the command

>NOTE:- Restart your PC and the drive X: mounted EFI partition disappears again.

CONGRATULATIONS
Linux OS is now completely uninstalled.

Install Programs in Windows 10

There are so many programs that you can install in your Windows 10 PC to help you perform a given task. These applications come from different providers, but the installation process is generally the same.

If you don’t know how to uninstall a program in Linux, we are going to help you out. Maybe a program is causing an error or you just want some free space on your PC. One way or another, one should know how to remove a program in

However, one thing we should know about Linux is that there are not just one way to uninstall (or install, for that matter) packages. It will differ depending on the version we are using.

Systems and package managers

The first thing we need to know when it comes to uninstalling a program in Linux is:

• what is a package system?
• what is a package manager?
• what system and package manager does my Linux use?

However, one thing we should know about Linux is that there are not just one way to uninstall packages.

A package system is a specific format in which software is packaged, distributed, and installed on our system. The package manager is, of course, the program responsible for installing, updating, and uninstalling the software.

Thus, different ‘families’ of distributions share the package system (and tend to share the manager as well); thus, those based on Debian (like Ubuntu and derivatives) have apt as format and apt-get as manager, those based on RedHat (like CentOS, Fedora, and derivatives) have rpm as format and usually have yum as manager (although Fedora uses a ‘fork’ called dnf), and those based on Arch (like Manjaro) use the tar format and the pacman manager.

How to uninstall a program in Linux?

All popular Linux distributions have some graphical tools capable of helping us to use the package manager without the need to enter commands in text mode. In fact, one of these tools is usually installed as standard, but there are also alternative options.

For example, in Ubuntu, we have the ‘Software Center’, which allows us to manage both APT and Snap packages, but we also have the option of installing Synaptic, the traditional graphical package management tool of Debian and all its derivatives (and which only manages APT packages).

The name and the exact operation of these graphical managers differ from one distribution to another.

Let’s say Synaptic graphical manager is running on Ubuntu. We just have to use its internal search engine to find the package we want to uninstall and tell Synaptic to uninstall it.
