If you have never worked with Linux before, then, probably, after installation, everything will seem unusual to you, and you will want to remove this system. We will look at several options for uninstalling Linux.

The easiest way to uninstall a system is to install Windows over Linux by formatting the disk. We will consider this option on the example of Windows 7. At the moment of choosing the type of installation, after accepting the license agreement, you will need to specify the section where the system will be installed. You will need to select "Disk Setup", then select the partitions on which the program to be removed is installed and start formatting the disk. You can keep the existing partitions or divide the disk again. After you install Windows, Linux will be removed from your computer. If you want to install another version of Linux, then you need to act in the same way - partition the disk, delete the old data.

If Windows is installed, then in order to uninstall Linux, you must delete the hard disk partitions that correspond to the system being removed.

How is this process carried out?

Windows must be loaded (log into an administrator account). Next, press Win + R, and then open the "Disk Management" utility by entering "diskmgmt.msc". now you need to select partitions that belong to Linux. Right-click on each of them and delete.

Not only the section is deleted, but also all the information that was stored in it.

Advice

If any important files are stored on the deleted system, then copy them to a flash card, or move them to partitions belonging to Windows.

After the partitions are removed, there will be space that needs to be allocated to the Windows environment. To expand a section, you need to right-click on the required section and select "Expand". Next, indicate the volume by which you want to expand the section. If you do not want to expand the existing partitions, you can simply create new ones.

Boot Loader Repair

After that, the computer needs to be restarted, but Windows will not start. The bootloader was removed along with Linux. This is not an error, but just a consequence of installing Linux in a Windows environment. During installation, you can see that there is a second system, so removing Linux also removes the bootloader. And now it needs to be installed using the Windows installation disc. We connect the disk on which the distribution is stored. Go to the "System Restore" section, where you need to select "Command Prompt". To restore the bootloader, you need to enter two commands:

• To create a boot entry bootrec / fixmbr
• To write the boot sector to the system bootrec / fixboot partition

After each command, you must press the "Enter" key. The bootloader is now restored and the system will start. If you are installing a new version of Linux, you will need to follow the same steps.

Conclusion:

There are several ways to remove the system. The simplest is to install a new one over the old system. If you need to uninstall Linux in a Windows environment, you need to delete partitions that belong to Linux in disk management and redistribute free space on Windows.

Uninstall linux and reinstall Windows

Ubuntu offers the user in general the same functionality as Windows, allowing you to browse the Internet using a browser, receive mail, work with office and graphical applications that are in no way inferior in their capabilities to their Windows counterparts. However, not everyone is ready to migrate to Linux, retraining to work with an unusual operating system and new applications. Experiments on the transition to Linux also do not always suit the users who started them with their results. Also, sometimes you need to remove Ubuntu just to try installing some other Linux distribution, such as Gentoo. So, very often it appears, Ubuntu with or.

In order to remove Ubuntu, you must:

1. Download Ubuntu.


2. Make a backup copy of all important archives and other files, the loss of which may be an unpleasant surprise. Better to put them on some external media, for example, or a drive other than the system drive installed on your Ubuntu.


3. Run the command sudo gedit /boot/grub/grub.cfg


4. In the configuration file that opens, delete the Ubuntu-related lines.


5. Repair the Windows bootloader. This can be done using the Recovery Console by running fixmbr and fixboot c:


6. As a result, after a reboot, the Ubuntu boot option will be absent, and you will be able to boot into Windows (of course, if this operating system is already present as an alternative).

If Windows is not on the computer, then simply install this operating system in the standard way.

To permanently uninstall Ubuntu, format the appropriate disk partition to NTFS after Windows boots. This will free up the previously occupied Ubuntu to accommodate Windows files and folders.

Users who have migrated from Windows to Linux Ubuntu will probably immediately notice the difference in the installation process and uninstall programs. It is because of this that many users are returning to more familiar Windows. But in fact, there is nothing complicated in this procedure.

You will need

• - a computer with Linux Ubuntu OS.

Instructions

One of the easiest ways to get rid of a program is to uninstall it using the "terminal". To do this, open the Application menu. To do this, click on it with the left mouse button. A list of sub-items appears. In this list, select "Standard", then - "Terminal".

Next, at the "terminal" prompt, enter Sudo apt-get remove. After the word remove, you must enter the name of the program that you want to remove. For example, you need to uninstall the Midori internet browser. Accordingly, enter the Sudo apt-get remove Midori command at the terminal prompt. After that, enter the user password. The process of uninstalling the program will begin.

Another way to delete program is to use the Synaptic tool. Select "System". Then go to "Administration" and select "Synaptic Package Manager". This will open the main menu of the application. In it, select "All". A list of all installed programs will appear. If necessary, you can also select a list of installed applications depending on the category ("Text Editors", "Games", etc.).

Find program which you will delete. After that, right-click on it and select "Cancel to delete" in the context menu. Another dialog box will appear. In this window, click on the "Apply" button. This program is now marked for removal. Next, in the main Synaptic menu, also click "Apply". The app will be removed.

If necessary, you can configure the settings for uninstalling programs. To do this, select "Settings" in the Synaptic menu, then "Options" and "Files". A window will open in which you will have the opportunity, for example, to configure the storage parameters of the program distribution kit or clear the cache after it has been uninstalled.

The Ubuntu operating system attracts many users with its originality of solutions and ease of installation. In the age of total distribution of Windows, free Ubuntu not only retains its market share, but also increases it in the segment of large industrial systems.

Preparing a USB stick for installing Ubuntu

To create a bootable USB stick with Ubuntu, use the WinSetupFromUSB program. You can download the WinSetupFromUSB 1.0 installation file from numerous Internet resources absolutely. Install the program on your computer and run it. Confirm the selection of the desired USB storage device. Select the Auto format it with FBinst command. Next, select the Linux ISO / Other Grub4dos compatible ISO item and specify the path to the Ubuntu disk image. After that, the computer will display a dialog box asking for a name in the boot menu - specify an arbitrary name. Click the Go button to create the Ubuntu installation stick. Keep in mind that during the download, all files that may have been stored on the USB flash drive before this will be erased.

Computer settings

To authorize the installation from a USB flash drive, you need to make changes to the computer settings. To do this, load the BIOS and set the USB stick as the first hard drive and the first boot device in boot device priorities. Remember to save your changes when exiting BIOS and restart your computer.

Installing Ubuntu

Immediately after booting from a USB flash drive, the computer will display a dialog box for choosing a language and options for using: installing Ubuntu or launching it without installing it. Confirm the choice "Install Ubuntu", you can select Russian as the system language. At the next stage, the installation wizard will ask you to check for free space and ask you to confirm the installation of third-party software. This software is related to codecs and it is best to download it. Follow the instructions on the screen until the setup wizard notifies you that it detects another operating system (Windows). There are several options: Windows can be uninstalled or Ubuntu can be installed as a second operating system. The third option applies to advanced users and represents an independent partition of the hard drive.

The most convenient option is to install Ubuntu as a second system. Choose this option and follow the instructions of the installation wizard. Please note that after clicking the Install Now button, changes will be made to the existing disk partitions and new ones will be created. This process will take some time. In the next steps, you will need to select the current time zone, keyboard layout and create an account.

After entering all the data, the installation of Ubuntu starts on the computer. When the installation is complete, you will be prompted to restart your computer.

On Ubuntu and derivatives operating systems, the guest login feature is enabled by default after installation. This function allows any user to log into your PC without a password. Even if the guest session is limited and a stranger cannot access your data, not everyone will like this feature. Fortunately, it can be easily disabled.

You will need

• -5 minutes of time.
• -Skills in the command line.

Instructions

We start the terminal emulator.

Let's open the display manager configuration file lightdm for editing with superuser rights. To do this, in a terminal window, run the command:
sudo nano /etc/lightdm/lightdm.conf.d/10-xubuntu.conf - for xubuntu or
sudo nano /etc/lightdm/lightdm.conf.d/10-ubuntu.conf if you are using ubuntu.

Enter your password when prompted.

Add the line allow-guest = false to the end of the file, as shown in the screenshot. Exit with saving: press Ctrl + X, then Y in response to the save request. We reboot the computer.

note

The user on whose behalf the editing is performed must have administrator (root) rights on the computer. By default, the first user created during the Ubuntu \ Xubuntu installation is that user.

Useful advice

To write commands faster in the terminal, use the TAB key for command completion. For example, by entering:
sudo nano /etc/lightdm/lightdm.conf.d/ and pressing TAB, you will make the terminal end the line by appending the only file in the folder to the end of the command, thus getting sudo nano /etc/lightdm/lightdm.conf.d /10-xubuntu.conf. If there are several files in the folder, the terminal will display their names for you and you can thus manually complete the command without errors.

A person who has recently switched to Linux often does not know how to perform even the simplest operations at first. One of these operations is formatting flash drives and memory cards. To do this, you will have to use the command line.

Instructions

Before connecting to a computer, put it into the recording resolution mode. It is carried out by such a miniature switch located on its body. If there is no such switch, the drive is always in this mode.
The same switches are sometimes found on SD cards, as well as on adapters for installing Mini SD and Micro SD cards into card readers.

By connecting a USB flash drive or installing a card in a card reader, do not rush to start formatting right away. Be sure to transfer all data from it to your computer hard drive. If the file system is corrupted, and formatting is done precisely for this reason, pull out at least those files that lend themselves to this.

If very important data is stored, but it was not completely removed, contact a data recovery specialist before formatting. Perhaps he will be able to extract some more files from the media.

After completing the data extraction, unmount the flash drive or card with the umount command. Without this, you will not be able to start formatting. But do not disconnect the media with the elect command - after that it will stop responding to calls until the next reconnection.

Usually, either the card is automatically assigned the designation / dev / sda when it is connected, and the only partition on it is / dev / sda1. Sometimes a medium has more than one section. Check if this is the case using the fdisk utility:
fdisk / dev / sda
It allows you to view sections, delete them and add new ones. The order of its use differs little from the order of using the utility with the same name in DOS and Windows, and therefore does not require explanation.

Complete formatting with the command:
mkfs.vfat -c -F 32 / dev / sda1
If necessary, replace / dev / sda1 with a different partition name. Please note that full formatting is a lengthy process, regardless of the operating system in which it is carried out, but it allows you to check the physical integrity of the media. If you are sure of its physical integrity, perform a quick format, which takes less than two minutes. To do this, run the same command, omitting the "-c" switch.

1.6. How to uninstall Linux

Any Linux distribution is removed in two steps:

1. Removing the Linux bootloader. The easiest way to restore the original Windows 98 boot loader is by entering the fdisk / mbr command at the Windows command prompt. If you have Windows 2000 / XP, the commands will help you restore the original bootloader. fixboot and fixmbr- in that order. You can also remove the LILO boot loader using LILO itself: log in as root and enter the lilo -U command.

2.Use the Linux installer to remove the Linux partitions. To do this, select the installation type "Install", then select manual partitioning, remove Linux partitions, save the partition table and reboot the machine by clicking Reset.

Remove template ‹class ForwardIterator, class T› ForwardIterator remove (ForwardIterator first, ForwardIterator last, const T & value); template ‹class ForwardIterator, class Predicate› ForwardIterator remove_if (ForwardIterator first, ForwardIterator last, Predicate pred); remove removes all the elements pointed to by the iterator i in the range)
