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. There is a long loading time when turned on, and 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 best way is to 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 remove 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 a 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 the BIOS settings. So, the boot disk is in your 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 a system from the BIOS using other third-party software, for example, Acronis Disk Director, but we will still consider removal 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 process 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 "Advanced 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 that contains the 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 is much simpler. 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 removing Windows from your computer, I suggest you install it not on a regular HDD, but on an SSD, as 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 a solid-state hard drive? Your system will boot in seconds! If you purchase a 1TB disk, all your programs will work!

Not long ago I installed two operating systems on my computer, on disk WITH: Windows 10 version 1803 is installed, and on the disk D: Windows 10 version 1809. Since this solution did not pay off, plus there was not enough free space on the hard drive, when you turn on the computer you need to choose which of the two systems you want to boot into or wait a few seconds to log into the system, it was decided to delete the second system. In any case, only one system is used, so we can remove the unnecessary one.

Today we will share with you an easy way to remove a second operating system.

First, you need to remove dual boot Windows 10.

1. Press the key combination win + R, and enter in the Run dialog box: , click “OK”

1. In the window that opens "System Configuration", go to the tab, then select the operating system you want to keep, and then click the button, "Use as default", see picture below:

In my case, the system I want to keep is on disk C:

1. Now select the system you want to remove with your mouse and click the button "Delete" and restart your computer:

After completing the above operations, all that remains is to delete all folders of the second operating system.

1. Go to the disk on which the system we do not need is located, in my case this is the disk D: and delete the following folders:

• Program Files
• Program Files (x86)
• ProgramData
• Windows
• Users

Since deleting these files is not an easy task, you have choices A, B, C:

A. If this disk does not contain the information you need: open "This computer", right-click on the disk where the system you want to delete is located, and select "Format".

WITH. Create a new folder and rename it to Windows.old, now move the folders indicated above into it, open "This computer", right-click on the disk where the system folders you want to delete are located, and select "Properties".

1. On the tab "General" click the button "Disk Cleanup":

1. In the next window, click

1. Check the box next to it and click the button "OK".

Be patient, deleting files from the second system will take some time.

A pressing question for many, from the computer. Its presence is indicated by the operating system selection window when the computer starts. When only one system is used, it is better to remove the other to free up space.

A computer may contain 2 or more operating systems; the choice from the available ones is made before starting. Quite often, maintaining several systems, especially on one logical drive, provokes problems, so the computer can slow down, and sometimes there are problems with user profiles. In general, the stability of such an OS is much less than a single installation of Windows.

How to remove a second Windows system?

The key method, provided by the manufacturer, of how to remove a second Windows 7 or 8 is to use a special tool located in the system configuration. This will remove the choice when turning on the PC, that is, the boot record will be erased, although personal data will still remain.

1. Press Win + R and type the word msconfig, then Enter;

1. The computer must be restarted.

After turning it back on, the option to select a different OS will disappear. If the problem is only the inconvenience of choosing a system, then you should specify a minimum waiting time, then the system itself will select the default version. You can configure this function by going to:

1. RMB on “Computer” and “Properties”;
2. Click on the “Advanced options” link;

How to completely remove a second Windows operating system?

In the previous version, we only eliminated the ability to start the OS, but the question of how to remove a second Windows from a computer was not fully resolved, since all the system files remained. Now you need to clean the system to free up a lot of free space.

To format a disk, you must first make sure that the target partition is selected. Its structure is identical to the system disk; it also contains the basic Windows folders, Program Files, etc. Usually the letter C is reserved for the main system, so the second OS will have a different identifier.

1. Click on Start, then “Computer”;
2. RMB on the target partition and click on “Format”;

1. If there is no special need, then leave the parameters as standard.

How to remove a second Windows 10?

You can remove the second operating system Windows 7, 8, 10 using the “Disk Management” section. The principle remains the same, the remaining OS activity should be cleaned up and the freed memory should be returned to an active state.

1. Click on Start and “Control Panel”;
2. Click on the “Administration” tile;

1. Now you should select “Computer Management”;
2. Among the list on the left side is the item “Disk Management”;
3. RMB on the partition that contains unnecessary Windows;
4. Select "Make partition inactive";
5. Again RMB and “Delete volume”.

Now the partition is completely deleted, and the remaining space after the volume remains unallocated. Therefore, it cannot be used for now. To gain access to the space, you need to create a volume; this is done by right-clicking on the unallocated space and selecting “Create a simple volume.”

After assigning a logical drive letter, you can write the necessary information to it without any restrictions.

You should know that if you uninstall the main Windows, the mbr will also be removed with it. This entry is required to start the OS and will need to be overwritten. The process of transferring an mbr partition has already been described earlier, so it will not be discussed in detail. We only note that you need to have installation media with the system. Then, after starting from it, select “System Restore”, the problem will probably be automatically found and fixed, otherwise you will have to manually transfer the entry.

Sometimes it becomes necessary not only to form the resulting space in a volume, but to add it to another section. Alas, this procedure, within the framework of standard Windows tools, will certainly affect the information, that is, the disk will be formatted. But if you use third-party programs, such an opportunity is present. A good example of a profile application is AOMEI Partition Assistant. The program is also capable of moving free space between already formed volumes without losing data.

This completes the removal of the second Windows, and after clearing the traces, it will remain only in memories. You can delete an unlimited number of systems in exactly the same way.

If you installed a new Windows operating system (any version), now when you try to turn on your computer, you probably first see a menu with the choice of the desired OS. This occurs if the hard drive has not been formatted. To prevent this from happening again, just remove the unnecessary version and only one version of Windows will remain on your computer.

Formatting a partition is the simplest and most obvious way

Before starting any actions, download information that is important to you onto removable media or one of your hard drives.

Reboot the system and make sure that the second OS is no longer there. If, when trying to format a disk, the system gives an error, then you can try using additional utilities for such operations, for example, the Acronis Disc Director program. It needs to be downloaded, installed and launched. It will delete everything itself, and then automatically reboot the system.
