How to uninstall software in linux

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
How to uninstall software in linux
(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.

Installing new programs to facilitate the accomplishment of various tasks in Windows 10 is not something that users do frequently. Also if some applications are not working correctly or you no longer need them, it is always healthy to uninstall them from your computer. Windows 10 provides various methods through which users can add or remove programs to or from their computer system. Below are the ways through which you can install or uninstall programs in Windows 10.

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.

  • To install a program you need to have the installation file in a disk, flash drive or downloaded and saved in your computer hard disk.
  • For instance, to install Microsoft Office, access the executable file and double-click on the file to start the installation.

  • If asked whether to allow the program to make changes to the computer, click “Yes” to continue.
  • Allow Windows to extract the installation files and launch the installation wizard.

  1. Before you start installing a program, it is important to check whether your system features meets the system requirements for the particular version of the program.
  2. Installation process differs from one program to the other but in most cases, the procedure is plug and play.
  3. The installation process may take seconds to a few minutes depending on the size of the program, but installation can run in the background as you continue working on your PC.

Uninstall Programs in Windows 10

For some reasons, you may want to remove an application from your PC. Windows 10 allows you to do so in two simple ways:

Method 1: Uninstall Programs from Windows Settings

  • Open the Windows settings and then go “Apps” settings.
  • Select “Apps and features” on the left-side pane and scroll down the page to find the program you want to install from the program list.
  • Click on the program and then the “Uninstall” button.

  • Click “Yes” to confirm the action – allow the program to make changes to the computer.
  • The uninstallation wizard will open. Follow the plug and play instructions to continue with the process.
  • Click “Finish” to complete the uninstalling the program.

Method 2: Uninstall Programs from the Control Panel

  • Search for “Control Panel” press the “Enter” key to open.
  • Navigate to “Uninstall a program” found under the programs category.
  • This will open a list of programs installed in your PC. Choose the program you want to remove.
  • Then click on the “Uninstall” option located at the top of the list. Select “Yes” when asked whether you really need to remove the program.

How to uninstall software in linux

  • The removal process will start and you can see the progress.
  • Follow the instruction keenly to completely and safely remove the program.

Windows Vs Mac

On Mac, the installation file will not be an executable .exe file. Mac installer file is a disk image file with .dmg extension. You can simply extract the file like a zip archive and use the application. However, some developers offer installer package which needs to be installed similar to Windows 10 programs.

The uninstallation process is also simple on Mac. You can simply drag and drop the app to trash to delete it from your computer. Learn more on installing and uninstalling apps on Mac.

Conclusion

From time to time, you will need to install or uninstall programs in Windows 10. Luckily, the installation and uninstallation process is similar for almost all application, and you can follow the above simple steps to add or remove any program on your PC.

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?

How to uninstall software in linuxHowever, 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.

How to uninstall a program on Debian and Ubuntu?

If we use Debian, Ubuntu, Linux Mint, Elementary Linux, Kali Linux, PopOS! or similar, we will only have to enter the following command in the terminal (and then enter our ‘root’ password):

sudo apt-get remove [package-name]

How to uninstall a program on Red Hat?

If we are using Red Hat or CentOS, we only need to enter the following command in the terminal (and then enter our ‘root’ password):

sudo yum remove [packagename]

If, on the other hand, we use Fedora Linux:

sudo dnf remove [packagename]

How to uninstall a program on Arch Linux?

We will only have to enter the following command in the terminal (and then enter our ‘root’ password):

Uninstalling programs on Windows is usually straightforward but inefficient. We always recommend you download a portable app whenever possible – What Is a Portable File and Why You Should Always Use Them.

TIP : Hard to fix Windows Problems? Repair/Restore Missing Windows OS Files Damaged by Malware with a few clicks

To simplify the process, we recommend you use an uninstaller to be sure the program is entirely uninstalled, including leftover files, registry entries, and more.

Uninstalling an application in Windows is slightly different depending on your Operating System, but you can find each in your Settings or Control Panel from the Start Menu.

Windows 10

Click on Start > Settings > Apps. Scroll down and click on the app you want to remove. Click on Uninstall.

Windows 7, 8, Vista

Click on Start > Control Panel > Programs or Uninstall a program. Double-click on any program to start the uninstaller.

Uninstalling Browser Extensions

There are many web browsers available, but the big three include Google Chrome, Mozilla Firefox, and Microsoft Edge.

Google Chrome:
Right-click on the extension and click on Remove from Chrome. If the extension is hidden, click the three dots in the top right corner and click on More tools > Extensions. Click Remove next to any extensions you’d like to uninstall.

Mozilla Firefox:
Right-click on the Add-on and click on Remove extension. If you don’t see your Add-ons, click the three lines in the top-right corner and click Add-ons > Extensions. Click on the three dots next to the Add-on you want to remove and click on Remove.

Microsoft Edge:
Right-click on the extension and click on Remove from Microsoft Edge. If you don’t see your extension, click on the three dots in the top right corner and click Extensions. Click on Remove under the extension you want to remove.

Uninstalling Android Apps

Click and hold the app’s icon and drag the app to your trash.

Summary

This article describes how you can remove the Linux operating system from your computer, and install a Windows operating system. This article also assumes that Linux is already installed on the hard disk using Linux native and Linux swap partitions, which are incompatible with the Windows operating system, and that there is no free space left on the drive.

Windows and Linux can coexist on the same computer. For additional information, refer to your Linux documentation.

More Information

To install Windows on a system that has Linux installed when you want to remove Linux, you must manually delete the partitions used by the Linux operating system. The Windows-compatible partition can be created automatically during the installation of the Windows operating system.

IMPORTANT: Before you follow the steps in this article, verify that you have a bootable disk or bootable CD-ROM for the Linux operating system, because this process completely removes the Linux operating system installed on your computer. If you intend to restore the Linux operating system at a later date, verify that you also have a good backup of all the information stored on your computer. Also, you must have a full release version of the Windows operating system you want to install.

Linux file systems use a “superblock” at the beginning of a disk partition to identify the basic size, shape, and condition of the file system.

The Linux operating system is generally installed on partition type 83 (Linux native) or 82 (Linux swap). The Linux boot manager (LILO) can be configured to start from:

The hard disk Master Boot Record (MBR).

The root folder of the Linux partition.

The Fdisk tool included with Linux can be used to delete the partitions. (There are other utilities that work just as well, such as Fdisk from MS-DOS 5.0 and later, or you can delete the partitions during the installation process.) To remove Linux from your computer and install Windows:

Remove native, swap, and boot partitions used by Linux:

Start your computer with the Linux setup floppy disk, type fdisk at the command prompt, and then press ENTER.

NOTE: For help using the Fdisk tool, type m at the command prompt, and then press ENTER.

Type p at the command prompt, and then press ENTER to display partition information. The first item listed is hard disk 1, partition 1 information, and the second item listed is hard disk 1, partition 2 information.

Type d at the command prompt, and then press ENTER. You are then prompted for the partition number you want to delete. Type 1, and then press ENTER to delete partition number 1. Repeat this step until all the partitions have been deleted.

Type w, and then press ENTER to write this information to the partition table. Some error messages may be generated as information is written to the partition table, but they should not be significant at this point because the next step is to restart the computer and then install the new operating system.

Type q at the command prompt, and then press ENTER to quit the Fdisk tool.

Insert either a bootable floppy disk or a bootable CD-ROM for the Windows operating system on your computer, and then press CTRL+ALT+DELETE to restart your computer.

Install Windows. Follow the installation instructions for the Windows operating system you want to install on your computer. The installation process assists you with creating the appropriate partitions on your computer.

Examples of Linux Partition Tables

Single SCSI drive

Multiple SCSI drives

Single IDE drive

Multiple IDE drives

Also, Linux recognizes more than forty different partition types, such as:

FAT 16 > 32 M Primary (Type 06)

FAT 16 Extended (Type 05)

FAT 32 w/o LBA Primary (Type 0b)

FAT 32 w/LBA Primary (Type 0c)

FAT 16 w/LBA (Type 0e)

FAT 16 w/LBA Extended (Type 0f)

Note that there are other ways to remove the Linux operating system and install Windows than the one mentioned above. The preceding method is used in this article because the Linux operating system is already functioning and there is no more room on the hard disk. There are methods of changing partition sizes with software. Microsoft does not support Windows installed on partitions manipulated in this manner.

Another method of removing an operating system from the hard disk and installing a different operating system is to use an MS-DOS version 5.0 or later boot disk, a Windows 95 Startup disk, or a Windows 98 Startup disk that contains the Fdisk utility. Run the Fdisk utility. If you have multiple drives, there are 5 choices; use option 5 to select the hard disk that has the partition to be deleted. After that, or if you have only one hard disk, choose option 3 (“Delete partition or logical DOS drive”), and then choose option 4 (“Delete non-DOS partition”). You should then see the non-DOS partitions you want to delete. Typically, the Linux operating system has two non-DOS partitions, but there may be more. After you delete one partition, use the same steps to delete any other appropriate non-DOS partitions.

After the partitions are deleted, you can create partitions and install the operating system you want. You can only create one primary partition and an extended partition with multiple logical drives by using Fdisk from MS-DOS version 5.0 and later, Windows 95, and Windows 98. The maximum FAT16 primary partition size is 2 gigabytes (GB). The largest FAT16 logical drive size is 2 GB. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:

105074 MS-DOS 6.2 Partitioning Questions and Answers
If you are installing Windows NT 4.0 or Windows 2000, the Linux partitions can be removed and new partitions created and formatted with the appropriate file system type during the installation process. Windows allows you to create more than one primary partition. The largest partition that Windows NT 4.0 allows you to create during installation is 4 GB because of the limitations of the FAT16 file system during installation. Also, the 4-GB partitions use 64-KB cluster sizes. MS-DOS 6.x and Windows 95 or Windows 98 do not recognize 64-KB cluster file systems, so this file system is usually converted to NTFS during installation. Windows 2000, unlike Windows NT 4.0, recognizes the FAT32 file system. During the installation of Windows 2000, you can create a very large FAT32 drive. The FAT32 drive can be converted to NTFS after the installation has completed if appropriate.

If you are looking for a quick solution to your problem, I would recommend that you ask for help in the forum for the Linux distro that you are using.

The command sudo apt-get –purge remove foxit should do the trick, but I am no Linux expert, so you should ask those who know Linux inside out before you take recourse to terminal commands.

How to uninstall software in linux

Most of us are dual booting operating system in our computers, means installing two operating systems in separate partition instead of using VMware or VirtualBox. Mostly people installs Linux-Windows combination in dual boot system. And always messes up during uninstalling either one of this OS from their system. In this article we will show you how to uninstall Linux or Windows from dual boot system.

Most of the users use Windows version of OS in their systems, but there are some nerds who want both Linux and Windows. And after a couple of months, some of them wanted to switch to a single operating system, either Linux or Windows and most of them always break their boot sequence while uninstalling Linux or Windows. For those guys this tutorial will help, actually uninstall Linux or Windows from dual boot system is not that difficult. So let’s start :

Uninstall Linux And Keep Windows:

First method for those who wants to stick on regular Windows version and like to uninstall Linux OS from their system.

  • First go to “Start Menu” and search for “Disk Management” and open up the Disk Management tool or you can simply hit “Windows key + R” to open Run dialogue box and type “diskmgmt.msc” to open Disk Management tool.
  • Next find out your Linux partition. It won’t be labeled since Windows doesn’t understand the Linux file system, so you’ll need to figure out which one it is by size and where it is on your hard drive.
  • Before moving to next step make sure you choose right partition. Now right click on Linux partition and choose “Delete Volume“. This will delete the partition from your hard drive, leaving free space.
  • Now you can see the deleted partition in green color labeling “Free Space“. Next, locate the Windows partition near the newly available free space, right-click it, and select Extend Volume. Extend the partition so that it takes up all of the available free space. Any free space on your hard drive will remain unusable until you assign it to a partition.
  • Yes you uninstall Linux from your system but its boot loader persists. So insert your Windows recovery media and boot from it. Choose “Repair Your Computer” go to “Troubleshoot” and then enter into Command Prompt. Type the following command:
  • And this will remove or uninstall Linux bootloader and replace it with Windows.
  • Reboot your computer and you should find that it boots directly into Windows, with no Linux partition to be found.

Uninstall Windows And Keep Linux:

This one is for those nerds who like to be a full-time Linux user or who hate Microsoft and their spying paid operating system. Mostly process varies with distros but the common method as follows :

  • Insert a live CD or USB for your Linux distribution and start up its partition manager (like Gparted). Find your Windows partition in Gparted’s menu—it’ll be listed as an NTFS drive.
  • Right-click on that Windows partition and choose “Delete” from the menu. Your machine may have other Windows-related partitions as well, like “System Reserved” and recovery partitions. If you want, you can delete these as well (but make sure you have recovery discs handy if you’re going to delete a recovery partition).
  • Right-click on your Linux partition and choose “Resize/Move“. Resize it so it takes up the rest of the now-free space on your drive.
  • Click the “Apply All Operations” button in the toolbar to perform the selected tasks. It may give you a warning saying that your computer may not boot, but with most Linux installations this shouldn’t be a problem (though if it is, check out this article to fix it). This process may take some time, so let it be!
  • When it finishes, you should have a hard drive with nothing but Linux on it. Your boot menu will still have some Windows entries, and it’ll work fine if you leave them there, but if you want to clean things up, just open up a Terminal in Linux and run:

So this is how to uninstall Linux or Windows from dual boot system. If you are stuck during any process feel free to seek out our help by commenting below.

Is there a way remove every bit of NI software from a computer?

The Windows uninstall application apparently leaves NI artifacts behind. Even though no NI software remains in the list of installed programs the next time I try to install NI software the NI installer recognizes that some pieces are already there. I get messages saying a newer version is already installed. Then the installation fails.

Will I have to reinstall the entire system to clean it up?

I read the procedure. It’s pretty complicated and hasn’t been updated to address Windows 7 specifically.

Since I have a deep and abiding fear of the registry I may prefer to format the drive and start over. Even though it means reinstalling a ton of other stuff I don’t want NI ghosts haunting me in the future.

Thanks for confirming my suspicion of how messy the process is.

PS: Shouldn’t professional software clean up after itself? In most neighborhoods people are required to remove any poop their pet leaves on someone’s lawn.

Seeing there are various ways to install on Ubuntu. What are the various ways to uninstall items?

Which ways always work? How can I be sure something was uninstalled?

How to uninstall software in linux

11 Answers 11

If the application has been installed via the package manager, all you have to do is run

That should always work. If the terminal isn’t what stirs your tea, you could open System → Administration → Synaptic Package Manager, search for the package you want to remove, click on the checkbox next to it and select “mark for removal”. Once you click “Apply”, the package should be removed. There’s of course also the Ubuntu Software Center. It’s pretty much the same thing as Synaptic. Just search for the application name and click the “Remove” button.

Sometimes applications can be split up into multiple packages (for example, many games have a separate package for their music). To make sure that you uninstall all related packages AND configuration files, you can type

or -in Synaptic- “mark for complete removal” instead of just “mark for removal”.

As for applications that have been manually compiled and installed, there’s not always a single way to remove them. The best thing to do is consult the README/INSTALL file that accompanied the source package – if one exists.

How to uninstall software in linux

The software centre: find the package, click remove

How to uninstall software in linux

Synaptic : the same

How to uninstall software in linux

apt-get:

aptitude:

It’s important to note that when you install things, they often depend on other packages. When you fire off apt-get remove

it doesn’t remove the automatically-installed applications by default. This is often safer (if you’re temporarily removing something like ubuntu-desktop) but this can mean you end up with a load of cruft.

aptitude will automatically remove things (as well as having a nice interactive command line interface)

You can also search for cruft in synaptic using the “local or obsolete” filter under the status section.

Here’s a rundown of the possible ways:

If the package has been installed via a package manager, you can remove it with one of the tools provided with this purpose:

  • dpkg –remove : the most basic command-line tool. Avoid.
  • apt-get remove or aptitude remove : these are the standard command-line tools. Aptitude is slightly preferred: it’s a bit more sophisticated. E.g., it can keep a log file of all package operations.
  • synaptic : GUI tool accessible through the GUI menu under “System/Administration”. Supports all features, a very nice program generally.
  • software center : even nicer GUI than synaptic . This is a better, updated version of the old “Add/Remove Programs”

All these get the job done. You can start with the most user-friendly (Software Center) and continue to aptitude, if you need certain features or install or remove programs very frequently.

Note that these operations remove the bulk of the program while sometimes leaving “configuration files” in locations such aus /etc/apache2. Most software doesn’t have configuration files there; some server software (“daemons”) do. In all but a few cases, keeping these configuration files will do no harm. If you want to remove everything, including configuration files, then you can use the “purge” operation. For aptitude, the command line is “aptitude purge.” (Tommy’s explication above of “purge” is not accurate. The “remove” operation, just like “purge”, deletes all dependencies that were pulled in with the original program.)

If the program tells you the package has been removed, you can be sure that the files are gone. Sometimes packages installed as a matter of dependency are not removed immediately. They will be eventually deleted, at a subsequent run.

As to software installed from other channels (typically compiled from source), you’re mostly forced to remove the files installed manually. They are often located somewhere in /usr/local . Some software provides shortcuts such as “make uninstall”. Don’t count on it, though. More often than not, the cleanest solution is to use the version provided through Ubuntu’s repositories, which can be uninstalled cleanly.
