How to remove Windows 7 step by step instructions. Removing old Windows after installing a new one - step-by-step instructions

To remove the operating system, first of all, we need to install the BIOS boot from installation media. It is worth focusing on what is in the installation disks operating system Windows has a built-in formatting program, during installation.

What changing the boot priority might look like in the BIOS is shown in the screenshots below.

First Boot Device– this is the first boot device to be checked, Second Boot Device– this is the second loading device, i.e. if the first one is not found, then it will be loaded in priority. And so on by analogy.

There are a huge number of BIOS varieties and it is not possible to give examples for every existing BIOS. The main thing you should know about BIOS is button to enter into it. This could be F2, F8, F12 or Del. See prompts when loading or rebooting. It can be seen in manual To motherboard.

In other words, your motherboard has a built-in BIOS; each individual BIOS has its own entry keys, but often they match. You just need to turn on the computer in time before Windows starts press the button(maybe even more than once) entering the BIOS, if you don’t have time, you’ll have to reboot again.

In more modern BIOSes, you can switch the boot priority by pressing a certain key, most often this is the F8, F11 key (but it’s better to look at the motherboard manual or search the Internet). Also, when you turn on and reboot, there are prompts (for example, BBS POPUP).

After changing the settings in the BIOS, do not forget save Otherwise you will have to do everything again. A request to save settings appears before exiting the BIOS

When is system removal necessary?

Firstly, if the operating system has stopped working adequately, cause this could be: deletion important system files, sloppy program work, targeted harm operating system viruses. Secondly, this is the user’s desire to change the operating system due to inconvenience or the desire to sell the computer completely empty.

By the removal process we mean replacing it with another operating system, but if you need to leave the computer clean, you just need to exit after formatting and not continue installing the OS.

The removal process for 7, 8, 10 will differ only in the formatting method, it will be a disk or flash drive with a new operating system or a special, pre-prepared drive with a formatting program.

Other ways to remove an operating system from a computer

In order to remove Windows using this method, you will need a previously prepared storage device (DVD, CD, Flash) on which there will be a formatting program. The programs are varied, but the principle of operation is similar everywhere.

Example of work Live CD AOMEI PE BUILDER

Some Live CD look like a regular operating system, although in fact they are loaded from a disk or flash drive. AOMEI PE Builder example.

Select the formatting program built into the Live Cd, in this case it is the AOMEI program Partition Assistant. Different Live CDs have different formatting tools.

Choose hard drive if there are several of them, select the drive with Windows, right-click on the drive and select format partition(Format Partition).

A confirmation window will appear, indicate the label for the disk, indicate file system(it’s better to leave it the same if you don’t understand this), leave the cluster size at the default.

After graduation formatting can be exited, the system will be deleted.

There is another way to remove windows. To do this we need to log in command line . In the case of a Live CD, go to Start and select “ Command line».

Now it is enough to use one single command - format x:

Instead of X write any drive letter and press Enter. After this, the operating system will kindly warn us about deleting all data from this volume. We agree by pressing the button Y And Enter. In the picture below you can see what deleting a disk from the command line looks like.

Sooner or later there comes a time when the user needs to remove his operating system. The reason for this may be that it has started to lag or is outdated and you need to install a newer OS that meets the latest trends. Let's figure out how to use various methods You can remove Windows 7 from your PC.

The choice of a specific removal method primarily depends on how many operating systems are installed on your PC: one or more. In the first case, in order to achieve the goal, it is best to use formatting of the partition on which the system is installed. In the second, you can use an internal Windows tool called "System Configuration" to remove another OS. Next, we will look in detail at how to demolish the system using both of the above methods.

Method 1: Format the partition

The good thing about the partition formatting method is that it allows you to remove the old operating system without leaving a trace. This ensures that when installing a new OS, old bugs will not return to it. At the same time, you need to remember that when using this method all information located in the formatted volume will be destroyed, and therefore, if necessary, important files must be transferred to another medium.

1. Removing Windows 7 by formatting can be done using an installation flash drive or disk. But first you need to configure the BIOS so that booting is done from desired device. To do this, restart the PC and when you turn it on again, immediately after the acoustic signal, hold down the button to go to BIOS. U different computers it may differ (most often Del or F2), but you can see its name at the bottom of the screen when the system boots.



2. After the BIOS interface is opened, you need to move to the section where you select the boot device. Most often, this section contains the word "Boot", but other options are also possible.



3. In the section that opens, you need to assign the first position in the boot list to CD-ROM or USB, depending on what exactly you will use - the installation disk or flash drive. After required settings determined, insert the disk with the Windows distribution into the drive or connect the flash drive to the USB connector. Next, to exit the BIOS and save the adjustments made to the parameters of this system software, click F10.



4. After this, the computer will reboot and start from the bootable media on which the Windows distribution is installed. First of all, a window will open where you need to select the language, keyboard layout and time format. Set the optimal parameters for yourself and click "Next".



5. In the next window, click on the button "Install".



6. Next, a window with a license agreement opens. If you simply want to remove Windows 7 without subsequently installing this operating system, then familiarization with it is not necessary. Just check the checkbox and click "Next".



7. In the next window, choose from the two proposed action options "Full installation".



8. Next, a shell will open where you need to select the HDD partition with the OS you want to remove. Opposite the name of this volume there must be a parameter "System" in column "Type". Click on the inscription "Disk Setup".



9. In the settings window that opens, select the same section again and click on the inscription "Format".



10. A dialog box will open, which will provide information that all data that the selected section contains will be permanently deleted. You should confirm your actions by clicking "OK".



11. The formatting process will start. After its completion, the selected partition will be completely cleared of information, including the operating system installed on it. Then, if you wish, you can either continue installing the new OS, or exit the installation environment if your goal was only to remove Windows 7.

Method 2: "System Configuration"

You can also remove Windows 7 using a built-in tool such as "System Configuration". However, you need to take into account that this method is only suitable if you have several OS installed on your PC. In this case, the system you want to delete should not be active at the moment. That is, it is imperative to start the computer under a different OS, otherwise nothing will work.

1. Click "Start" and go to "Control Panel".



2. Next, enter the area "System and Security".



3. Open "Administration".



4. Find the name in the list of utilities "System Configuration" and click on it.

   

   You can also launch this tool through the window "Run". Dial Win+R and enter the command into the field that opens:

   Then press "OK".



5. A window will open "System Configurations". Navigate to a section by clicking on the appropriate tab.



6. A window will open with a list of installed operating systems on this PC. You need to select the OS that you want to remove, and then press the buttons sequentially "Delete", "Apply" And "OK". It should be noted that the system with which you are currently working with the computer cannot be demolished, since the corresponding button will not be active.



7. After this, a dialog box will open asking you to restart the system. Close all active documents and applications, and then tap .



8. After restarting the PC, the selected operating system will be removed from it.

Choosing a specific method Windows removal 7 depends primarily on how many operating systems are installed on your PC. If there is only one OS, then the easiest way to remove it is using the installation disk. If there are several of them, there is an even simpler uninstallation option, which involves using a system tool "System Configuration".

Good afternoon, friends. I think every user has noticed that after he installed a new operating system, this OS begins to work like a well-oiled clock. Everything loads quickly and correctly. It's a pleasure to work with such a system.

But time passes, and the system begins to slow down. Happening long loading When turned on, the system also takes a very long time to turn off. The same thing happens with programs installed on this system. They take a long time to load and do not work correctly.

Of course, the most best way, clean the system. I have written more than once about cleaning the system in my articles. I even wrote two free books about this: - “ How to speed up your computer? And " How to properly clean Windows?».

But let's say the user has already decided to delete this system and install a new one. Although, we delete systems not only because of failures. Quite often this happens when a new OS is released. When the user simply wanted to install new system. In both of these cases, the old system will have to be removed.

Also, the system is often removed when there is another parallel one, and the second one becomes simply unnecessary for us. So how to do it right? Today we will look at three ways to completely remove Windows 7 from your computer, although this applies not only to Windows 7, but also to other operating systems.

How to remove Windows 7 from your computer - replace it with a new system

We will do this by using the installation disk, which we will load from the BIOS. To do this, during system boot, select BIOS settings. So, boot disk in your disk drive. As soon as you click to turn on the computer, immediately press F2. Moreover, you need to do this before loading the Microsoft logo.

You will enter the BIOS settings, from where you can select the boot order of the disks on your PC. We enter the Boot section.

To do this, click on CDROM and set the priority.

Then press F10 to save the settings. Now we can remove our system by installing another operating system on it, the one you decided to install. At the same time, you can remove the system from the BIOS using other third-party software, for example, Acronis Disk Director, but we will still consider removing it by installing a new one on the old system.

This is the most common and convenient method. I will not talk about all the nuances of installing the system, especially since I already have an article on the topic of installing the system. I’ll just explain that if you already have a system installed and you decide to install another one on it, then during the installation of the system, before choosing the partition where you will install the new system, the old one must be formatted.

To do this, being in the window for selecting a disk for installing the system, you need to click on the line at the bottom of the “Disk Settings” window.

Then, we will have a warning about deleting all information from this section. Which is exactly what we need.

Our disk has been formatted. Then, all you have to do is continue installing the new operating system.

To speed up your Windows installation, I recommend:- Computer accelerator.

How to remove a second Windows from a computer First method

Many users have two systems. We will consider the case when both of them are on the Hard Disk, but in different partitions (often people put the second system on a virtual disk in the same partition).

So, to do this, right-click on the “Computer” shortcut and select properties. A window will open with our disk partitions. Select " Additional options" in the left column.

The “System Properties” window appears. In the “Advanced” menu, select “Options” above the “Boot and Recovery” line.

Then the most important thing begins. In the window that opens, you need to select the system that you want to leave, from which the download will occur. If you make a mistake, the system simply won't boot.

Click OK. Also, this method is suitable if you just want to remove the second Windows from the boot menu.

We need this action to eliminate surprises. For example, if the default boot is the system that you want to remove, and you do not change the system, the computer will simply not start working.

Now, close all open windows, click on the “Computer” shortcut with the left mouse button. In the window that opens, select the disk on which there is a parallel system that we want to delete. In my case, this is drive D. To do this, right-click on the drive and select “Format”.

In the window that opens, select “Start”. We get a warning about the consequences of formatting. Click OK and the disk with our second system is completely formatted.

How to remove parallel Windows from your computer Second method

This method much easier. To do this, just enter “System Configuration” into the command line or msconfig and open the program. Select the “Download” menu. In the window that opens, we will have information about our operating systems. Since I currently have only one system, the program shows one system.

Then, select the system that needs to be removed and delete it by clicking on the “Delete” button.

After completing the procedures, it is advisable to clean the registry. The task is completed, the second system is deleted!

You now know how to completely remove Windows 7 from your computer and you shouldn’t have any problems with this. Also, I’m interested in your opinion on this issue in the comments! Good luck!

Friends, after uninstall Windows from a computer, I suggest you install it not on a regular one HDD drive, and on solid state SSD drive like I did. Disks on a page range from 120 to 960 GB, i.e., actually 1 TB. You can purchase it from the link... on AliExpress. Judging by the description, the disk is suitable for both Computers and (laptops).

From the screenshot you can see the disk volumes. If you need to install the system, it is enough to purchase a disk with a capacity of 120 GB. If it’s a full-fledged hard drive, then, at your discretion, from 480 to 960 GB. Why do I recommend installing Windows on solid state hard disk? Your system will boot in seconds! If you purchase a 1TB disk, all your programs will work!

Some users love Windows 7 and don’t even want to talk about any other operating system. And someone, apparently obsessed with the spirit of conservatism or due to the remarkable abilities of their PC, abandons the “seven” and returns to the old XP. This is despite the fact that it is no longer supported by Microsoft. However, lovers of everything new also agree with these comrades. Without delay or any doubt, they remove Windows 7 and install the new distributions of Windows 8.1 and Windows 10.

All these zeal, in principle, are understandable and justified. And then, according to taste and color, when choosing an operating system, there are no comrades. The question is different. How to remove Windows 7 so that there are no elements left of it on the hard drive, and so that it does not interfere with the installation of another system?

The solution to this problem depends on the specific situation and user intentions. Let's look at the most common removal methods from Windows computer 7.

Disk formatting

With this approach, Windows 7 is completely neutralized during the installation of another system by completely formatting the disk (that is, its contents are completely erased). The installation disks for both XP and Windows 7/8 have everything necessary tools to implement this function. Let's learn how to use them.

Note. If you do not want to switch to a new system, but simply want to reinstall Windows 7, correctly remove the old distribution and install a new one, you can also use the instructions below.

1. Insert the installation disc of the operating system you want to install (XP, 7, 8 or 10) into your DVD drive.

Attention! Before following the next step in the instructions, find out which key on your computer activates the menu for configuring the boot of disks and devices, or the BIOS (add-on shell) into which this menu is integrated.

2. Click "Start". In the drop-down menu (shutdown), click the left arrow icon and select Restart.

3. During the reboot process, hold down “F2”, or “F8”, “F9”, “F12” (depending on the computer manufacturer! see note).

When the “Please select boot...” window appears:

• use the cursor arrows to select CDROM from the list;
• press "Enter".

If disk boot order is performed in the BIOS, do the following:

in the “BIOS SETUP UTILITY” menu, go to the “Boot” tab;

open the “Boot Device Priority” subsection;

V additional window“Options” use the up and down keys to select “CDROM”.

After completing this setting, when you restart the PC, first of all turn not to the system partition, but to installation disk. Which is what is required in this case.

Windows XP:

• upon completion of the preparation procedure, when the XP installation menu appears, press “Enter” (thus, you select the first item - “Proceed with installation”);
• press "F8" to accept the agreement;
• select the system partition (the partition on which Windows 7 is currently installed) and press “Enter”;
• select the “Format partition... NTFS” function from the list or the same function marked “Quick”. And press "Enter" again.

Upon completion Windows formatting 7 will be completely uninstalled and the installation of Windows XP will begin.

Windows 7/8:

• wait for the installer components to load into the PC memory;
• select the system interface language;
• in the new window, click “Install” (the message “Starting installation” will appear);
• enter license key, click “Next”;
• accept the agreement;
• in the “Windows Installation” window, click on the system partition (on which Windows 7 is located);
• at the bottom of the same window, click “Format”;
• When formatting is complete, click “Next” and continue with the installation.

These steps will allow you to correctly remove the old OS (in this case, “Seven”) and install a new one.

Removing a second system

This method of removing Windows 7 is suitable if several systems are installed (for example, XP and 7). Either the “seven” was uninstalled or installed incorrectly and when the PC starts, it displays a menu asking you to load one of the existing systems, although one of them is not working. (For example, a copy of Windows 7 is listed.)

How to remove an unnecessary distribution from the disk (or a non-working copy of Windows 7), do the following:

1. Press the “Win+R” keys simultaneously. (The Run window will appear on the display.)

2. In the “Open” line, type - msconfig.

3. Click "OK".

4. In the “System Configuration” settings panel, go to the “Download” tab.

5. Select the OS you want to remove from your computer by clicking the mouse.

6. Click the “Delete” button, and then “Apply” and “OK”.

All. The system has been neutralized. Now when you start your PC, the system selection menu will no longer appear.

How to delete the Windows.old folder?

The Windows.old folder is automatically created by the system when updating or reinstalling the OS without formatting the system partition. Takes up about 2-15 GB of disk space. It stores backups important system components that are used when rolling back (restoring) Windows 7 to previous settings.

To remove it from your computer, follow these steps:

1. Press the “Win+E” keys.

2. Right-click on the system partition (drive C).

3. Select in context menu"Properties".

4. On the General tab, in the properties window, click Disk Cleanup.

5. In the cleaning settings window, click “Clean system files».

6. When the procedure is complete, return to the list of items and check the box next to the “Previous Windows installations” object.

7. Click OK.

8. In an additional window, confirm your intention to delete the Windows.old folder: click “Delete files”.

If all operations of this instruction are performed correctly, then Windows.old will safely disappear from the hard drive, and on drive C free space there will be more.

Today, in this lesson, we will learn with you how to correctly remove programs in Windows 7. If you think that it is enough to place the program folder in the trash, then you are mistaken. Many people do this by simply deleting the folder, but this is not true.

Each new program leaves an entry in the registry, during operation it can save its files in other folders, etc. All this will remain on the computer if we simply delete the program folder.

Let's look at a few the right ways uninstalling programs in Windows 7.

Let's go to " Start - All Programs».

We find the folder with the program here, open it and run the “Delete” or “Uninstall” file there.

If there is no folder with the program that needs to be deleted, then go to “ Start - Control Panel».

The entire list of programs that are installed on our computer is displayed here. Any of them can be deleted. We find the one we need, select it with the mouse and press the “Delete” button.

In the window that opens, confirm the deletion.

We are waiting for the process to complete and the program to be deleted.

You can also go to the folder with installed program and remove it by running the “Uninstall” file, if you find it, it doesn’t always happen.

Here are the ways you can uninstall a program in Windows 7 using standard means.

In addition to this, there are also special utilities that are designed to remove programs and clean up all “tails”. I know one of these, it's called Revo Uninstaller. Removes all program roots, very convenient, works quickly.

Having launched it, we will see in the main window all the programs installed on the computer; to remove any one, you need to right-click on it and select “Delete” in the menu that appears.
