How to change windows system. How to reinstall Windows yourself: the easiest ways. Checking disk space

In this article, I will talk about how to independently install the Windows 7 operating system from a disk to your computer or laptop.

I offer detailed step by step instructions with a visual demonstration of screenshots of the installation operating system Windows.

If you think that installing an operating system is something complicated and incomprehensible that only a specialist can handle, then I will disappoint you: this is not true. Now you will see for yourself.

All you need to install Windows 7 (or Windows 8) is a computer or laptop, an operating system disk (because in this article we will install Windows from a disk), detailed instructions, which I will now give you, and, perhaps, attentiveness! I hope that after installation you will not look like . 🙂

After installation, I recommend installing immediately. You understand that in our time of electronic payments, this is very important. Also now (yet) nowhere without Adobe Flash Player . Like him right install read . You may also be interested in the very not bad. If stored on a computer private information, create a .

Important: Most of all possible problems that occur during the installation of Windows 7 is due to an incorrectly prepared installation disk and (or) the quality of the “OS assembly” written to it. How to burn an operating system image to disk, you can read in the article.

Remember: if this is a disc not out of the box, that is, bought in a store, then you need to use only original images from Microsoft MSDN. It is the original image, which is also available on the Web, as well as various assemblies, that is the key to the successful installation of Windows and its normal functioning.

Do not use assemblies of unknown origin. You put all third-party fixes, fixes, homemade builds at your own peril and risk. The consequences may be irreversible.

Before installing Windows 7:

Remember two main things to do before installing Windows.

First is to decide in advance which section hard drive system will be installed. Typically, in most cases, this is the C:\ drive. Remember (or create) the volume label and size.

Remember, your desktop is located entirely on the C:\ drive, or rather, here: C:\Documents and Settings\ Username \Desktop. Think in advance about the integrity and safety of files that are archived for you, copy them from the desktop, that is, from drive C, to another drive or flash drive.

All programs installed on the C:\ drive will also be removed, but this is not a reason to drag the entire folder with programs to other drives. It is much easier to reinstall these programs on clean system. Don't be lazy, it's not every day you reinstall Windows.

Second the moment is the drivers for your computer or laptop. They need to be taken care of in advance. They are included with most laptops, but if they are not available (or need to be updated), we look for them on the official website of the manufacturer and download them in advance.

Everything you need to know about installing drivers, I recommend reading the article "Installing Drivers or Five Iron Rules", which is located.

If you skip this important point, then after installing Windows, you may be left without the Internet, because it is not a fact that the windows distribution kit will initially contain your network card drivers.

Installing Windows 7 from disk:

We insert the disk with the Windows operating system into the drive and restart the computer. By the way, if you do not have a drive, then you can install the Windows operating system using the usual.

Let's continue. Our task is to configure the computer to boot from a DVD. This can be done in 2 ways:

  • 1. select a device (DVD) in a special boot menu;
  • 2. change the boot priority in BIOS (from HDD to DVD).

The first method, choosing a device in the boot menu, is easier and more convenient. After installing Windows, there is no need to return the boot from the HDD (hard disk). However, this feature is not available on older computers, in which case you will have to go into the BIOS and change the boot priority.

Start - reboot, wait for the screen to go out and at the first sign of the system waking up (the appearance of the logo), press and hold the Delete key on the keyboard. Why the Delete key? These keys can be F1, F2, F3 + F2, F10, Ctrl + Alt + Esc, Ctrl + Alt + S, Esc.

There is no universal button to enter the boot menu or enter the BIOS, and it all depends on the manufacturer of the computer (motherboard). The surest way is to read the instructions from the computer or from the motherboard. The table below shows an illustrative example of such keys.

The boot menu looks something like this:

Press F10, agree and confirm the exit with saving (Save and Exit) by selecting "Ok".

Phoenix Award

Consider the second version of the interface. To boot from a disc, you need to change the priorities so that the DVD drive is the first device. We find the item “Advanced BIOS Features” and use the arrows to switch to the first device (First Boot Device), change to CDROM.

Press F10 and confirm the exit with saving (Save and Exit).

If you have problems at this stage, I recommend watching this video.

Let's continue. If everything is done correctly, we will see the following window with the inscription: "Press any key to boot from CD or DVD".

Here you need to press any key, for example, the spacebar. This is done only 1 time and only at this stage of the installation. We see the following window with the inscription "Windows is loading files".

Files are being extracted, after which we will see the inscription Starting Windows and the Windows 7 installation window itself. Windows installation has begun !!

Select the desired language and click "Install".

Next, we need to select the edition of Windows 7. Choose the one for which you have a key or which you are going to activate. On laptops, it is usually indicated on a piece of paper with a key located on the bottom of the laptop. Entering the serial number itself will be a little later, it has been moved to the end of the installation.

A few words about the ability to install a 32-bit (x86) or 64-bit version of Windows. If you have more than 4 GB of RAM (aka RAM, RAM, Memory), then set it to 64-bit, if not, then 32-bit (x86).

Read and agree to the terms of the license. Next, we need to select the type of installation - select "Full installation".

Now you need to select the partition on which Windows will be installed.

If you have this partition reserved by the system (note that it is still in megabytes (MB), not gigabytes), for example, as in the following screenshot, then select Disk 0 Partition 2.

In order not to be so excruciatingly painful when choosing a partition, before installing Windows, look at how many gigabytes your C drive occupies.

If you have one partition on your hard disk and it is more than 250 GB, then it would be more correct to create two local disks. One section is specifically for Windows (usually about 50-100 GB are allocated), and the other is for storing your personal information (how much will remain, XXX GB).

Note: The partitions you create should be named Disk 0 Partition 1, 2, 3..., not "Unallocated Disk Space". Otherwise, the operating system simply will not see partitions with such names.

If necessary, create a section or sections and click "Apply":

Attention: problems may arise at this stage - when Windows 7 asks for a driver for further installation or when the system does not see your hard drive in order to continue the installation.

Or install (if prepared) hard disk controller drivers. If you already have two or more partitions on your hard drive, then you can skip the above paragraph. So, we have selected the "System" section, and now we need to start formatting.

The installer warns that all our data will be deleted. We need this, because we are interested in a clean installation of Windows. We agree and wait. The whole process usually takes a matter of seconds. After formatting, we see that there is more free space, calmly click "Next".

And here is the beginning of the installation, the process is started. You can take a breath.)

We are waiting, sir ... Usually it takes 15-25 minutes. When our system installs, it will prompt you to enter a username and computer name. Enter.

If you wish, you can enter a password and a hint. Windows will then prompt you to enter serial number. Enter (if any). If not, then skip this step and uncheck "Automatically activate when connected to the Internet."

Any Windows 7 or XP operating system installed on a computer or laptop starts to work slowly or freezes over time. You can solve this problem by trying to remove all sorts of garbage. To do this, you can run cleaning programs, such as Ccleaner and antivirus. Sometimes it helps, sometimes it doesn't. If you have the second case, then nothing can be done with the PC. You need to reinstall Windows 7 or another operating system, such as XP on a laptop or PC. In general, any OS is reinstalled according to the same principle. Moreover, the newer its version, the easier it is to remove the old system and install a new one.

This guide will tell you about clean Windows installation 7 or XP via BIOS. You can do this yourself using one of two methods: using a USB drive or a disk with a system image (the image can be downloaded via the Internet). Using a flash drive is much easier. In addition, when reinstalling on a laptop, there may be no disk drive. Therefore, installing from removable media can be the only way. How to do it yourself installation flash drive with Windows 7 or XP read here. Whichever method you choose: from a USB drive or a disk, the following instruction may help you. So, let's look at how to reinstall Windows 7 or XP on a laptop correctly.

How to reinstall Windows 7

To begin with, it is worth mentioning that when reinstalling the operating system on a laptop or PC, all programs and data located in the memory of the system disk (usually this is the local drive C) will have to be deleted. Therefore, all files, as well as application data, if possible, should be transferred to the memory of another local PC drive, for example D, or saved on external media or on a cloud service on the Internet. Through the explorer, transfer all files and folders to a safe place.

Also, now is a good time to think about PC drivers. If you do not have the appropriate disk, then they can be found and downloaded via the Internet from the official website of the manufacturer. It is correct not to use unreliable utilities and drivers found on the Internet, as they may contain viruses.

You will need drivers for a video card, a sound module, a network card (responsible for connecting to the Internet via a LAN cable), Wi-Fi, Bluetooth, etc. First of all, it’s right to take care of the drivers for working online via the Internet on a laptop. If you only have one computer, then this will be appropriate. Since without them you will not have access to the Internet and you will not be able to download everything else. To make dealing with drivers easier, you can download a program for them. automatic installation. DriverPack Solution, which works offline, is quite suitable:

Please note that the image of the Windows 7 or XP operating system must be the same version as that installed on your PC or laptop. For example, you have Windows 7 Home Edition or Ultimate. So install the same version correctly. Otherwise, your license key indicated on the computer case will not work. You can find out exactly which version of the system you have installed by clicking on the folder " My computer» right click mouse and selecting " Properties". Here you can see what you have installed. How they differ read on the Internet.

Starting the installation correctly

Now, through the BIOS of the PC, you need to boot from a USB flash drive or disk. The BIOS is the starting point - the program that is flashed into your motherboard. Typically, the computer starts from the hard drive on which the system is installed. But now you need to change the boot priority and start the computer through the BIOS from a USB flash drive. To do this, when you turn on the computer, depending on the manufacturer, press the correct key or key combination. In most cases, this is the Delete button. What to click on a particular model can be seen below in the picture. The BIOS will open on the laptop or PC - device selection menu:

After that, the computer will boot from the USB flash drive or installation disk through the BIOS. Next, following the prompts, we proceed to start installing the operating system on the laptop. We don't need the BIOS anymore. Select the language of the system and installation:

After accepting the license agreement, a window will pop up with the hard disk partitions you have. If the old system was in your memory of the “C: /” partition of your hard drive, then you need to right-click on it and format (delete all data). If you are doing this for the first time, then you can get by with a quick format of the disk (surface cleaning). However, to completely delete the data, you need to use careful formatting (it will take a little longer). The speed of the operation also depends on the power of the device.

After that, select the formatted partition and click the Next button (we perform the same sequence of actions for any other version, including XP).

The reinstallation of Windows 7 will begin.

It remains only to wait for the computer to complete the operation. If the installation is interrupted due to the fact that the PC reboots and starts again from a USB flash drive, then this problem must be solved using the BIOS.

In the BIOS of the computer, you need to set the initial boot priority in order to start again from the hard drive. After that, the installation will continue.

When installing Windows 7 or any other version of the system (XP) downloaded from the Internet, you will be asked for a product key. It can be found on the case of a PC or laptop. Here's what the sticker looks like:

What can you do if you do not have such a sticker? In this case, enter the code that you purchased online from the official Microsoft website.

We hope that the instruction "for dummies" helped you and now you will know how to reinstall Windows 7 or XP. In this article, we wanted to shed light on such terms unfamiliar to beginners as BIOS, bootable flash drive, etc. So, as you can see, if you follow the procedure outlined here, you can quickly and easily reinstall the system.

Friends, many letters come with the question of how to properly reinstall or update the Windows 7 operating system and what is the actual difference between these two concepts.

Letter #1. Please bring clarity to a vague question for many than reinstalling Windows 7 different from the update and which is better to prefer? The operating system 7 that I have installed behaves extremely unstable, it takes a long time to load, many programs have stopped installing, sometimes errors of this kind occur, for example, some system file or dynamic library is missing. Rolling back with a restore point a significant amount of time ago did not help. I do not want to reinstall again, as many programs are installed. You said in your comment that you need to restore system files, put things in order at startup, optimize Windows 7, or, as a last resort, update or reinstall Windows 7, but unfortunately I have not heard anything about the latter.

I would like to know first:
How to actually carry out this update or reinstall the operating system and what will happen to my personal files on the system partition, will they be lost?
Secondly: they say that the update is launched only from a running operating system. Is it so? After all, in XP it was possible to run an update even when the system did not boot at all. Thanks in advance, Pavel.

Reinstalling Windows 7

To make everything clear to you, I will guide you through the process of updating my operating system, and then I will show you how to reinstall Windows 7 in two ways and you will see everything with your own eyes, but first I will still explain to you what an Update is and Reinstalling Windows 7.

What is a Windows 7 update?

this is a system installation over the old one, that is, you insert a disk with the Windows 7 distribution kit and start the system installation right in the running seven, but in the installation menu you choose not a full installation, but an update. What does she give?
First of all, damaged system files will be replaced, working system files will not be replaced, with your own personal data: installed applications, documents, music, nothing will happen, all your programs will start and your entire household on all disks will remain untouched. Also, user accounts will be transferred without changes, all this will be done by the tool - Transfer Tool Windows Data(very important files, it's still better to transfer them manually). I also want to say that you will have to re-enter the product key, select the language, region, set the time, and so on. Warning. If you have non-genuine Windows 7, then after the upgrade you will have a window in the lower right corner of your desktop with a warning that your copy of Windows is not genuine.

  • Another frequently asked question is how does Data Transfer Tool work? At windows update 7, temporary folders of your data will be created containing information about accounts and user settings, your Email, files in the Favorites folder, personal files and user folders - music, images, videos, as well as settings for installed programs. As your system is updated, all data will fall into place, and temporary folders will be deleted. When upgrading, the data transfer tool does not allow the user to select files to transfer, but when reinstalling, you can choose what you want to transfer (details later).

Will the update solve all your problems related to the operation of Windows 7? In most cases Yes, but unfortunately no one can guarantee a 100% result here. In my opinion, if possible, it is better to delete and re-format a partition with a poorly functioning operating system, after transferring all important files to other hard drive volumes or USB portable media and reinstall the system with all programs.

  • Note: Windows XP has the same update mechanism and can be run both in a running operating system, and in cases where you cannot log into Windows XP due to problems, then you can boot from the XP installation disk and select setup menu option, . Be aware that unfortunately there is no such possibility in Windows 7 and the update can only be carried out in a working operating system.

What is reinstalling Windows 7?

Reinstallation is a complete replacement of all operating system files, that is, formatting a partition with an unstable system and installing Windows 7 again. Naturally, all your files and the system itself from the disk (C:) will be deleted. In order to transfer all your files from your system drive (C:), you will need to use Windows Easy Transfer, but it will no longer work automatically, as in the case of an update, but we will use it ourselves and we will also choose what we need to transfer from the old system to the new one.

  • Now the question arises: What is the difference between reinstalling the system and installing it again? Friends are here. When reinstalling Windows 7, if you wish, you can use the File Transfer Tool, since you already had the system installed once, but when you simply install the system again, install the system on the partition of the new hard disk you created. In short, I don’t know how to explain it even more clearly!

What can I say, let's first update my Windows 7 together, and at the end of the article we will reinstall the system using the file transfer tool, it has also been working with errors for me lately and you will see with your own eyes, and then select what you need.

Windows 7 update

Paste installation disk from Windows 7 to the drive, if you do not have autorun, click setup.exe.

Before updating, we can connect to the internet and download Latest updates from Microsoft official website

Choose Update

Compatibility check

copying Windows files

Collecting files, settings, and programs, Unpacking Windows files, Installing features and updates, Transferring settings and programs files

The computer restarts.

In this place, you need to boot from the hard disk, and not from a bootable USB flash drive or boot disk with Win 7.

Update registry settings

Enter the key

We set the time

The update process has been completed, the accounts have been saved

I have all the files in place, all programs run.

Reinstalling Windows 7

Now let's find out what Reinstalling Windows 7 is. According to the rules, we will reinstall Windows 7 on the same disk on which the old operating system is installed. If earlier Windows was installed, for example, on the partition (C :), then you need to reinstall it also on the partition (C:) and NOT on any other partition (otherwise it will be installing a second operating system). All your files on the partition (C:) will be replaced with the files of the newly installed Windows 7 operating system.

  • First of all, we will launch the Easy Transfer tool, which will copy all our personal data from the Windows 7 partition to portable media or another hard drive partition, then boot from the installation Windows disk 7 (how to set in) and install the system again. Immediately after installing Windows 7, we will launch the Easy Transfer Tool and copy back all our files, in the end we will get with you a new operating system and all our data: music, documents, personal folders, and so on.
  • Note: You may ask: Is it possible to run a new system installation directly from a running Windows 7 and not climb into the BIOS. Answer: This method is given at the end and we will also consider it.

Let's now see what the Data Transfer Tool will transfer from our files, launch it.

Start, write in the input field Data transfer tool

In this window we see detailed information we will now choose which files we can transfer from the old operating system to the new one.

The data migration tool suggests us to use:

  • Data transfer cable - a cable specially designed for this purpose, which still needs to be bought, is used to transfer files between two computers, in principle we do not need this, because we have one computer.
  • Network - transferring files over the network is also not our option.
  • External drive or USB flash drive. What we need. If you don't have much data, you can even use an 8GB or 16GB flash drive. By the way, if you don’t have a USB flash drive or a portable USB drive, you can use another partition of your hard drive for storage, like me.

So you have selected External disk or USB flash drive, and I have a partition on the hard disk (D:).

We select This is my source computer, that is, the data needs to be transferred from it.

Data is analyzed and can be transferred to new system, in step Usernames and General items, click Settings, and also, if you click Advanced, then a complete picture of what the Data Transfer Tool will include in the archive will open.

Please note that the folders of both users of the operating system and personal data are included in the archive, this is correct. But we definitely don’t need to transfer the data located on all partitions of the hard disk, except for the system one (C :), since we will be reinstalling Windows 7 located on (C :) and the reinstallation process in our case will only affect the system partition ( FROM:). Uncheck all hard drives.

However, if you decide to transfer data from all partitions, then you can leave the checkboxes unchecked, just keep in mind that the data transfer file in this case will take up a very large volume ..
What else should not be included in the archive that the data migration tool will create? For example, you can not include the C:\Program Files folder, it will be more reliable to install all programs again after reinstalling Windows 7.
So click Save, you can assign a password

File transfer is in progress. On disk (D:) a migration file is created with the extension (MIG)

Now it's the turn to reinstall Windows 7, insert the installation disk with the seven into the drive and reboot, at the beginning of the installation it is better to click on the Disk Setup button and select Format the partition with the previous Windows 7, but in general the whole process is step by step, starting from changing the priority of the boot device in the BIOS and before installing the operating system itself, is described in our article.
I think you did it and installed the system, now let's use our Data Transfer Tool again.

Choose This is mine new computer(requires transferring files and settings to this computer)

Your external hard drive with the data transfer file should already be connected.
I, in turn, specify the hard drive partition (D :), the transfer file is located there.

We can click Settings and select files to transfer to the new system manually, as we have already done with you, or simply click Transfer.

The transfer is completed, we can see the report, as well as make sure that all your files have been transferred to the new system.

There are many reasons to reinstall Windows: for example, your computer is infected with a virus or is so cluttered that it constantly slows down. And if it's not your hardware (and in most cases it's not), then reinstalling the operating system will return your computer to a working state. In this article, we will explain how this can be done.

Warning: before a clean installation of the system, you need to do backups all your files, music, photos, videos and settings. If you don't have a second hard drive, then you can save the files to . A clean install is when you completely format HDD and start from scratch.

It is also possible to install Windows "on top" of an existing version of the OS - the so-called "upgrade", which is a less drastic way to fix problems and in which you are unlikely to lose your files and programs. But even when updating the system, we recommend that you perform a backup.

But this method has a minus - this is the probability of leaving something that worsens the performance of the PC and does not completely get rid of viruses. This is why a clean install is preferred.

How not to lose your license

Before you begin, if you haven't already, link your Windows 10 license key to your Mircrosoft account. If this is not done, you may not be able to activate the system after reinstallation.

Click Start → Settings → Update & Security → Activation. If there is only the inscription “Windows is activated with a digital license”, then it is definitely not tied to a Microsoft account.

To fix it, follow the path Settings → Accounts → Your details, click "Sign in with a Microsoft account instead" and follow the instructions. Once the process is complete, you can check your status in the Activation section. There should now be an inscription "The system is activated using a digital license tied to your account Microsoft.

Reinstall Windows 10 on a working computer

If you are able to boot into Windows 10, open the Start menu, click the Settings tab, and then click Update & Security. Then click on the "Recovery" tab and use the "Reset your computer to its original state" function. This option will give you the option to choose whether or not to keep all your files and programs.


Reinstall Windows 10 on a non-working computer

If your PC is unable to run Windows 10, try the following steps.

Look at the messages that appear before the OS logo appears. Some laptops and PCs have a "hidden" hard drive where its original copy is stored. In this case, a message like "Press F10 to start the Recovery Wizard" usually appears.

What will this lead to? will happen complete removal information from the hard drive, after which a hidden Windows version. As a result, you will receive a PC with factory settings.

Pressing the F8 key while booting the computer will bring up the menu Windows boot, which should contain a line like "Repair your computer".

If none of the above worked


When all preparations are done, insert the DVD into the drive and restart your computer. If everything is fine, then the PC will boot from the disk. If it will, as usual, boot into Windows, then you will have to go to BIOS menu(using the F2 or Del keys when booting up the computer) and select the drive as the first device to start up.


Once done, save your changes and restart your computer again. Now it will boot from the disk and the Windows installation window will appear, in which you need to select the system language, keyboard layout, time and date format.


The next window will ask you to select the installation type. Select the item "Full installation" or "Custom", which will completely clean the system and return the PC to factory settings. You can also select the update mode. It will save all the information, but will not always fix existing technical problems.


Then a window will appear with the choice of a partition on the hard drive for installing Windows. Only one section available? Then just choose it. If there are several sections, then select the first main one and click "Next".


After that, the installation process of the operating system will begin. At the bottom, an indicator of its progress and stages of implementation will be shown. It can take some time. It often seems that the installation is stuck at the "Completing installation" stage, but this is not the case. Be patient and don't turn off your computer.


Ultimately, you will be taken to the profile settings menu. Also here you need to enter the license key, which was mentioned earlier and which will be needed to activate the new operating system when an Internet connection appears.


Then you will be prompted to select security settings (we recommend choosing standard), time and date format, and connect to a wireless Internet connection, if one is available.


Finally you will see a working Windows table, which, however, will appear empty. Your next task will be to reinstall the various applications that you regularly use.


But that is not all! Go to "Device Manager" and check for drivers for all your hardware. If the list is unknown device with a question mark icon, just go to the manufacturer's website and download latest version required driver. To do this, you will need to find out the exact model name of your laptop or the names of the hardware models of your PC.


Even if the system installs its standard drivers and you will not notice any problems in the operation of the computer, you should still install the original manufacturer's drivers on motherboard and a video card.

In addition, special utilities (especially for laptops) may become available to you, which will not be restored when you reinstall Windows. For example, for some laptops there are utilities that prevent the battery from charging to 100%, thus extending its life.

At the very end, you can copy back all the backup copies of your files.

Sooner or later in the life of every PC user, there comes a time when you have to reinstall Windows. There can be many reasons for this, for example, an outdated system, viruses that the antivirus cannot defeat, a large number of system errorswhich are easiest to fix by reinstalling the OS.

Today we will take a step-by-step look at how to reinstall the Windows operating system and avoid data loss at the same time.

Preparing to reinstall Windows

Windows 7 will serve as an example in this article. In principle, you can install other versions, both old and new, in the same way. Before proceeding to reinstall Windows, you need to take a few preparatory steps. To begin with, you must clearly understand that your actions jeopardize the safety of your data, so if you are not sure of your actions, you should ask another person for help for these purposes.

First of all, copy important information for you to a USB flash drive, hard drive or any other medium. It can be photos, music, documents - in general, everything that is very dear to you. Be sure to check the files in the folders The documents, Downloads, on Desktop. If your hard drive is divided into two partitions, or if your system has two drives, make sure that all important information saved on drive D: A when Windows installation you need to pay attention to the size of the disk on which the system is installed, so as not to accidentally erase the second disk.

Preparing bootable media

After that, you need to prepare bootable flash drive or disk. Do not follow this step if you have system disk or other media. Personally, I use conditional free program UltraISO, with an intuitive interface, for creating bootable flash drives for various purposes.

It is also important to determine which version you want to use and whether you will have any problems activating the license. Windows not only differs in the year of release, but also in the bitness of its operating system. Well, if you have a disk with a system from the manufacturer, otherwise you will have to decide in advance on the version of the operating system. If you have installed RAM 4GB and above, it makes sense to use a 64-bit system.

Reboot in BIOS

Next, you need to restart your computer and enter the BIOS. To do this, you should use both the DEL, F2 buttons, and others provided by the manufacturer of your laptop. In it you need to select a boot device. It could be a floppy drive USB device, depending on where the system image is located. If on a flash drive, then select USB (the flash drive must be inserted), save the settings and restart the computer.

System installation process

Your computer will start to boot and run the system installer. Everything is relatively simple here. Follow the installer's instructions. The installation process is divided into several stages, after each one is completed, a check mark will appear opposite.

Please note that during installation you will be offered a disk selection menu for installing the operating system. You can either delete all existing partitions or format only partition C without deleting information from partition D:

When the first step is completed, the computer will restart. At this point, you need to start the BIOS again and put a bootable hard drive or pull out the media with the image. Save the settings again and restart the computer. The installation will continue.

Upon completion of all stages, you will receive a clean, brand new system. The only thing left to do basic setup systems. Note that everything before installed programs will be deleted forever, and if you do not take care of saving important data, there is a risk of losing them forever.

If you have installed a pirated version, then it is quite possible that it will already contain basic drivers and a minimum set of necessary (or even harmful) programs. If not, then you will have to look for all this on your own. It is best to download drivers from the official Microsoft websites, as well as from the websites of the manufacturers of your PC components.
