Complete reinstallation of windows 10. Reinstallation of Windows

Useful tips

Let's consider this situation. You had Windows 7 or 8.1 installed. Then you updated it to Windows 10. The system was activated automatically. And now you need to completely reinstall Windows 10 without losing your license. Will there be problems with activation?

“Ten” should be activated automatically if you install the same edition that was installed and activated before (for example, Pro x64 Russian) on the same computer. With the release of the Threshold 2 update, the system activation procedure has been significantly improved and simplified. It should now be easier to activate Windows 10 both during a clean install and an upgrade.

Reinstalling Windows 10 while maintaining license and activation

0. Step number zero: before reinstalling the OS, make a backup copy of the boot and system partitions if your license or software installed on the system is extremely important to you. We have, of course, checked the instructions below, but anything can happen. And it is better to have a backup copy so that you can restore Windows to its current state at any time.

1. Create an installation flash drive or disk with Windows 10 software.

The creation procedure has not changed, however, no matter what time you create a bootable flash drive, the distribution package recorded on it will always be up-to-date thanks to the proprietary Microsoft utility Media Creation Tool. Let us remind you that in assembly 10586 the mechanism has been significantly simplified Windows activation 10. Now the system can be activated with a key from Windows 7 or 8.1.

2. Connect the USB flash drive and simply restart your computer.

3. from this flash drive.

4. When prompted to enter your product key, select Skip:

Reinstalling the OS: Skip entering the product key

5. Format only system partition. (In most cases, “drive C:”. Use the disk capacity in GB as a guide.) Other sections do not need to be formatted.

6. Then select the formatted partition to install Windows 10 and click Further.

Format drive C for subsequent OS installation

After installation, the operating system must be activated (if it was activated legally before reinstallation). After a couple of days, when you are convinced normal operation a freshly installed OS, you can free up disk space.

Other ways to reinstall Windows 10 on a laptop

If your laptop was sold with Windows 10 pre-installed, then you have another way to reinstall the operating system if necessary. Each laptop manufacturer has its own special procedure system recovery. For example, if you have an HP laptop, you need to restart it and press the F11, for Samsung it is F4. Lenovo does have special button — Novo Button, which serves to enter the BIOS and restore (in fact, reinstall) Windows.

To reinstall Windows 10 on Toshiba laptops It is necessary to hold down the key when the laptop is turned off 0 (zero) on the main keyboard unit, without releasing it, turn on the laptop Power button. Release the 0 key when you hear a sound system dynamics. Some laptops come with a recovery disc. You need to boot from it and run the Recovery program.

The difference with the procedure we described in the previous paragraph is that when reinstalling Windows by recovery procedures you get the operating system without current updates- as it was at the time of purchasing the laptop. But the essence remains the same - you somehow perform a clean reinstallation of the system, getting rid of all the glitches and problems of the old operating system.

No matter how carefully you pay attention to what you download on your computer, no matter how reliable the antivirus is, reinstalling Windows is necessary, and this will need to be done. That's why step-by-step instruction process Windows updates 10 will be useful to many. Incomprehensible files, lack of space on the computer and slow operation are the first signs that this is simply necessary.

Before we begin the procedure, let's note a few important points.

First, check for important files. If your computer has additional disks, then photos, videos and necessary documents It's better to send them. If this is not possible, then you can simply save it to a flash drive - a modern and convenient way. In general, protect yourself and save useful and necessary information and after reinstallation.

Secondly, check that the computer boots from regular DVD disk from the drive.

All preparations have been made. Finally, we note that the reinstallation process can be divided into the following main stages:

Creating a boot disk (assuming there is none);
booting computer from Windows disk 10;
the reinstallation itself.

Boot disk and its creation

To perform the Windows 10 reinstallation process, you must have a disk with the operating system on it.

You can simply skip this part of the entire procedure if you have such a disk. Well, if it doesn’t exist, then to create it you need:

A disk image with Windows 10 in a specific format;
a program for burning the necessary disk images.

Little and easy. In this case, absolutely any program is suitable. Let's take for example ImgBurn. This program is simple. And what is equally important: it does not require additional funds, it can be easily downloaded.

So, the first step at this stage is to launch the program. And then you should click on the button located in the upper left corner.

After clicking it, a field for recording disk images appears. At this stage, you need to indicate to the program the location where the ISO file mentioned above is located: click the button with the folder icon and select the file that is needed.

Having selected the file to burn, insert the disc into the drive and click on the large button at the bottom of the window that appears. This click will begin recording the disk image onto the disk you prepared and inserted.

Stage two - booting your computer from a Windows 10 disc

The previous stage is completed: the disk has been created. Now you need to boot your computer from this disk. To do this, firstly, you need to enter the BIOS, and, secondly, enable boot.

It is easy to enter the program after performing the following simple steps:

To restart a computer
Wait for the download to start
Press the login button

Difficulties this procedure will not cause it, especially since a hint field is usually displayed on the screen.

After going into the settings of the downloaded program, go to the section BOOT(translated this word means “Loading”).

In the field that you will see after clicking this button, you must select a subsection with a name, as in the photo below:

After selecting it, a list of three or more items will appear, opposite which it is explained which device will be loaded at each specific stage.

Since we are now loading from disk, we need to select the first item, which is highlighted in white in the above picture. And then change its value to CDROM.

So, the matter is coming to an end. We finally complete the change of value by saving the settings. And then you can quit the program altogether. This is usually done using the F10 key.

The only thing left is to reinsert the disk and restart the computer. When booting from disk is enabled in the program, a field with the inscription “Press any key to boot from CD or DVD” will appear on the screen.

And now the final touch remains: press any key and wait for the installer to appear, with which you can proceed to the third stage and begin the Windows 10 update process itself.

The reinstallation process itself in action

Well, now we move on to the very last, final stage of the system update. This is the third stage.

Loading the disc was successful if a field appears on the screen with the ability to select several standard parameters. This an important part procedures, since right now it is necessary to specify the time format, the language that will be on the computer, as well as the keyboard layout. Having indicated everything you need, click on the Next button and move on to the next part of the process.

The step that follows this is to press the key indicating the intent - Install.

By pressing the button indicated above, a splash screen appears on the screen, indicating that the selected parameters are being configured.

So, we are gradually approaching the choice of installation method: just an update or a complete reinstallation. If there is a need to reinstall Windows 10 from scratch, then the choice should fall on the second option. If the situation is different: you want to keep the existing files, settings and applications of your 10 version, then you should choose the first method.

So, the choice is made, and a field with a list is opened hard sections disk. When performing a complete reinstallation, you need to mark only the partition on which the system is installed. Care at this stage of the process will help you avoid mistakes (all data in this section will be irretrievably destroyed). Next, click the button “ Format» .

There are two formatting methods: quick and normal. It is recommended to choose the second; it does not take much longer than the first (for comparison, 1 minute to 10), but is much better and more effective. You need to mark your choice with arrows and click Enter key. Formatting has started, and when it is finished, the Next button will take you further. Important point: Before pressing this key, make sure that blue The partition that was formatted a few minutes ago is flooded.

The field that will then appear on your computer screen will inform you that the files are being copied.

It will take a few minutes to copy and reboot. When will the computer do everything? necessary updates and starts working, you will see a long inscription. You don’t need to press anything, the download will happen automatically.

After waiting for the download, we will see configuration options that need to be done at the very beginning:

with standard settings and no additional questions
manual setting

For ordinary users, the first option is a priority, so we will not deviate from the standards.

So, the first option is chosen. Clicking it displays a form for entering your Microsoft account login and password. They need to be entered. And then secure it with the Login key.

But you can simply skip the account protection step offered by the program.

The inscription that appears on the screen will change to a traditional screensaver after a short period of time.

The update process is complete. This is how you can reinstall the system on absolutely any computer. Now you can go directly to setting up the system and installing the programs you need.

It should be noted that if your computer is cluttered, it is not at all necessary to reinstall Windows 10. In this case, a clean reinstallation of the operating system is quite suitable.

A clean reinstall is possible:

In a running system
If there are problems loading
If it is impossible to download

You can do it by saving music, documents and photos in profiles, or without it.

Complete reinstallation or clean - it's up to you. But detailed guide presented here will help you reinstall Windows yourself without any complications or problems. There is no need for specialists or additional expenditure of funds: just get started and take action. Good luck.

Video on the topic

For many users this process may cause difficulties. There are several methods for reinstalling the system, each of which has its own advantages. Let's look at the most common methods for reinstalling Windows 10.

How to back up your data

It is strongly recommended that you back up your data before reinstalling your system. Windows 10 has built-in tools that make this task much easier - you don't even need to install additional programs. It is enough to complete simple steps“File History” component.

Step 1: Enter “Windows Updates” into the search engine Windows string, select “Windows Update Options” from the results lists and go to the “Backup” menu. You can also access your settings by going to Settings > Update & Security > Backup.

If the Automatically backup files switch is set to On, File History is already backing up files, including contacts, desktop items, and files in your OneDrive folder. This function automatically creates copies of files in the Documents, Videos, Music, Images libraries, so place required folders and files into these directories.

Step 2: If the “Automatic file backup” switch is set to “Off”, then the first step is to add a disk.

Click the Add Disk button and Windows 10 will automatically search for an external drive that you can use to store your backups.

Select the drive you want to use for File History and Windows 10 will search for external hard disks For Reserve copy.

After selecting the drive, the archiving service will start automatically. You can click the “Other options” link to change how often files are copied and how long the backups are retained. You can also configure in detail which folders and libraries need to be copied. Depending on the amount of original data, the backup process may take some time, but you can continue with your normal activities while the task is completed.

You can check the current status of the archiving service by clicking the “View” link Extra options” on the “Archive Options” page. As a result, the “File History” window will open in the control panel, where you can view the service status and additional options.

If you prefer to store backups on external drive or in cloud storage, then you have this opportunity! No matter which method you choose, make sure that everything important files added for copying.

How to restore Windows 10 to its previous state

Sometimes when solving computer problems, restoring the system to a certain point in the past can be a great help - say, reverting the OS to a few days or weeks ago. This is an ideal solution to get rid of errors associated with recently installed applications. Windows 10 offers several options to roll back the system to an earlier state.

Step 1: In the “Update and Security” window, go to the “Recovery” tab. On the page that opens, you will see the option “Return to a previous version of Windows 10.” Click the “Start” button and wait a bit.

Step 2: After briefly asking why you are reverting to a previous build and checking for updates that might fix the problem, Windows will begin analyzing the information available for recovery. Follow the onscreen instructions until the build selection screen appears. In some cases, the operating system cannot find the necessary files that are used to roll back to a previous version, especially if you are in Lately performed disk cleanup. In such cases, it is better to look for another solution.

Step 3: If the preparatory operations were completed successfully, then you can roll back the system to previous build. This measure will help get rid of problems caused by the recent system update. If possible, choose the most stable and working Windows assembly 10. In some cases, you will have access to previous operating systems on your computer, such as Windows 8.

Using system restore points

You can restore Windows status 10 using a system restore point, This method will be especially useful when you need to return to previous versions Windows 10, instead of skipping back all builds.

Step 1: Go to Control Panel by typing "Control Panel" in Windows search. Turn on View > Large or Small Icons and select the “Recovery” section, and then click on the “Run System Restore” link. Then, confirm that you want to go to this mode. Users can also create new recovery points and configure the recovery procedure.

Step 2: By default, the recommended restore point will be selected, with a description of what action was performed before the specific point was created. You can also select other restore points on this screen. Select the “Select a different recovery point” option and click “Next” if you want to see other recovery options.

Note that Windows usually creates a restore point after major changes, such as installing new program, driver or update. If you don't see any recovery options available, then system protection may be disabled. In this case, you will have to perform a complete reinstallation or look for another solution to the problem.

Step 3: Find the restore point that preceded the problem in the system. Then click “Next” and confirm to start the recovery operation by clicking “Finish”. Keep in mind that this operation should not delete personal files.

How to reinstall Windows 10

Sometimes recovery operations may not solve problems that are too large and may require full reset systems to remove damaged data or when preparing a computer for sale.

Step 1: Go back to the “Recovery” section in the “Update & Security” section of the “Settings” application and select the first available option- “Return the computer to its original state.” Click the “Start” button to continue.

Step 2: You will be given several options that allow you to customize what data you want to clear. If you want to fix the problem while continuing to use your computer, then select the “Keep my files” option (and be prepared for the second option if the first doesn’t work). If you want to perform a full system reset and have already double-checked the integrity and safety of your backups, then select the “Delete everything” option. If you are selling your computer, you should perform a factory reset, which will return your computer to its original state. Please note that the latter option is not always available. In this case, the programs that were preinstalled when you purchased the computer will be reinstalled.

Step 3: Confirm your choice and wait for a while. If you are performing a reset on a laptop or mobile device, then make sure it is connected to the network. The system will automatically reboot after the recovery is complete.

Typically, activation is automatic and does not cause difficulties, regardless of whether you reinstall or restore the Windows 10 system. If you are using a local account, link Windows key 10 to your account Microsoft records for a simpler reactivation when updating the computer configuration.

If you have problems with activation, open the Update & Security section in the Settings app and go to the Activation tab. Here you can see your activation status or add another product key. Follow the onscreen prompts to reactivate your Windows 10 installation.

Reinstallation of the operating room Windows systems 10 can be done in two ways: by resetting to the factory version or completely. We discussed the first option in detail in a separate article. It involves rolling back the “ten” to its original state - essentially, a complete reinstallation, but with the ability to save user files if desired.

In this article we will look at a way to completely reinstall the system, with full formatting hard drive during it or also with the possibility of saving personal files on separate section. A clean installation of Windows 10, in our opinion, has some advantages over a rollback. The system does not save any personal settings, but it takes up less space than resetting (since it does not save the previous installation in the Windows.Old folder), installs faster and, as a rule, works a little faster and more stable. In the same time setting "tens" completely implies the creation bootable flash drive. Fortunately, it’s not at all difficult to do - Microsoft has released special program, which completely automates this process.

Before recording installation USB drive, just in case, you need to clarify the parameters of your Windows 10 operating system: its version ( Home or Pro) and bit depth (32 or 64 bits). You can do it like this:

RIGHT click on the Start menu.
Select "System".
In the parameters window that opens, look at the release and system type.

This option is possible when this moment You have a 32-bit Windows 10 operating system, but an x64 processor. In this case, you can install a 64-bit system on your computer. This should be done if the size random access memory computer (looks in the same window - the “Installed RAM” item) is 4 GB or more. If the RAM is less than 3GB, then you must install the x32 version.

There is no need to delete data from your hard drive or format it! All this can be done during the installation process, just like saving a separate existing partition with personal files.

Now let's move on to recording Windows files 10 per flash drive. For this we need the actual USB drive with a volume of at least 4GB. We insert it into the computer, and we ourselves go to Microsoft official website for the utility for creating installation media "tens". On the page indicated by the link, select blue button « Download the tool now", and then run the downloaded file MediaCretionTool.

At one time, when launching the MediaCreationTool utility, it was observed error 80072f76 0x20017. It was associated with “jambs” exclusively on the Microsoft side and arose everywhere around the world from September to December 2017. At the moment the problem is solved, but in such cases for downloading Windows image 10 from the official website you can use the “crutch”. You can download the top ten directly by replacing the user agent in your browser with Apple Safari. Everything is simple there: press F12 in the Edge browser - then go to the “Emulation” tab - change the user agent line to “Apple Safari (iPad)” - download necessary images With Microsoft official website(described in more detail here in English). If access to Edge browser you don’t have it due to the lack of Windows 10 anywhere and you decide to trust me (by the way, completely in vain - because you can’t trust anyone on the Internet), then here I have links to ISO files in the cloud Mega storage with the latest versions of Windows 10 as of December 2017: 32 bit and 64 bit. I will say right away that downloading from there will most likely be slow. It’s faster to use the method with the official website and changing the agent in the browser. After downloading ISO image with Windows 10, using any of the described methods, you need to create a bootable USB flash drive from this installation image. This can be done using the utility Rufus.

After this, some time may pass before the Windows 10 Setup program starts. It will first do the preparation and then ask you to accept the terms of the license. At the next stage, the user is asked what he wants to do. We need " Create installation media" Next, select the language, architecture (32 or 64 bit) and release. If you plan to reinstall Windows on the same computer, then most best option has already been selected by the program (check the box “Use recommended settings for this computer”). Then select the media - USB. Well, in the next step we need to indicate which flash drive we will use for recording. Please note that all information on it will be deleted!

After this it begins Windows boot 10. Depending on the speed of the Internet connection, this stage may be the longest - during it, “Microsoft” is downloaded from the servers installation image operating system weighing about 3 GB. Then the download is checked for a while and creation begins Windows media 10. Upon completion, the program informs us that the USB flash memory device is ready, and then, having deleted no longer needed data, it closes.

The MediaCreationTool utility only runs, but is not installed on the computer, so there is no need to remove it after using it.

Clean installation of Windows 10

Here we are ready for complete reinstallation Windows 10. Just in case, check that all necessary personal files have been copied from the computer to removable media and reboot the system.

Booting your computer from installation media

Now our task is to prevent the machine from booting from the hard drive, but to force it to boot from our installation flash drive. To do this, at the moment when the system starts and reports the possibility of selecting loading methods, you need to press the button responsible for Boot Menu(or Boot Agent, SetUp) - select boot options (it’s better to press several times for reliability). The image below indicates that in this particular case you need to press F12. Call buttons boot menu vary depending on the laptop manufacturer or motherboard computer. Usually this is F12, but there are other options: F8, F9, F11, Esc and so on.

If everything was done correctly, the system will offer us an option from which media the computer should be booted. You need to select your flash drive and press Enter. The pictures below show two possible options described events. Sometimes when pressed function button(for example F9 on Asus laptops) loading from the flash drive immediately begins without the selection list appearing. Since there are many computer manufacturers, there are too many ways to start installing Windows 10 from a flash drive to demonstrate everything. If something remains unclear, do not hesitate to ask questions in the form of comments under the article.

Installing the Windows 10 operating system

After the computer boots from the installation flash drive, the Windows 10 logo appears on the screen and after a while the installation begins. If necessary, change the default language, time and currency format, as well as the keyboard layout. Then click “Install”.

Soon the Windows 10 activation window appears. Select the “I don’t have a product key” option. If your system has already been activated on this computer, then it will automatically receive activation after installation.

Select the installation type “Custom: Windows installation only (for advanced users).”

A list appears before us existing sections hard drive. If you want to keep some section with personal files, leave it, we will delete the remaining sections. To do this, select the section with a mouse click and click “Delete”. At this stage, you can create two or three partitions the right size(for example, one for Windows 10 and programs, the second for personal files), but we recommend leaving one partition, that is, deleting everything that is there. The fact is that for separate storage of personal files it is better to use a second physical HDD, and not a separate volume on an existing one.

Go to “Unallocated disk space...” and click “Next”.

Begins reinstall Windows 10 completely. It has five stages: copying, preparation, installation of components, then updates, and finally completion.

After this, the computer reboots and the initial self-configuration of the installed operating system continues: services are started, devices are being prepared, etc.

Then the system prompts us to select the country where we are located and the keyboard layout.

It is proposed to add a second layout. Strictly speaking, this means third layout- English is always installed by default, we have already selected the second (Russian) at the previous stage, now you can install the third, for example, German, French or Finnish. If this is not necessary, skip this point.

After this, the system checks your Internet connection and updates. If your computer doesn't have wired connection, but there is wifi adapter, then you are prompted to connect to an existing wireless network.

You can then log in to Microsoft account to use it instead of the traditional local one account Windows. If you don't have an account, you can create one. You will need an address for this. Email and password. The benefits of logging in with a Microsoft account include: automatic synchronization some of your data and files. We will consider the option of creating offline account. Select the appropriate item at the bottom left.

Now enter the username, and then come up with a password (you can skip it - then there will be no password). If the login to the system is protected by a password, then in order not to enter it every time, you can come up with a 4-digit PIN code. Enter, confirm, click OK. This option is especially convenient for those who log into Windows 10 using a Microsoft account. You can skip this step ("Delay" button).

Now we need to select privacy options. Those who are afraid of surveillance by Microsoft (American authorities, the world behind the scenes, etc.) can turn off all the options. We recommend disabling only “Speech recognition” - this function still does not work in Russian yet.

After this, the system will talk to us a little more (“Hello”, “Preparing for you”, “This may take a few minutes”, “Let’s get started!”) and start - the desktop will appear.

It is quite possible that, like in the picture, you will see a message about searching for a video driver. It will be installed automatically, but until this time the screen resolution will look unusual: unclear, with large elements. Don't be afraid of this. You will immediately be asked whether to allow “other computers on this network to detect your PC.” If you are connected to the Internet at home or at work, feel free to answer “Yes” if public network, then no. To make it easier to understand what we are talking about, we inform you that this question is an analogue of this installation message from the times of Windows 7.

Immediately after the first launch of a freshly installed Windows 10, we recommend checking available updates operating system. To do this, go to the Settings tool (the gear icon in the Start menu), select Update and Security, and then click Check for Updates. Next, in parallel with the process of downloading OS updates, you can begin installation necessary programs. By the way, this is very convenient to do using the Ninite.com website (this is not an advertisement - it’s just really convenient). There you can tick all the programs you need and download the installer at once (the “Get Your Ninite” button), which, after launch, will install them into the system without any unnecessary questions and, most importantly, without any spam add-ons.

Windows 10 (latest operating system Microsoft system) offers many improvements and features. Paying Special attention collaboration, applications and data synchronization, it not only benefits ordinary users, but also for business people.

Moreover, even such an optimized OS is not protected from errors and failures software or malware attacks. Surely, for some reason, you encountered undesirable circumstances. Windows 10 is in an unusable state, so now you need to reinstall it. Otherwise, you probably purchased new equipment or want to transfer data to a new system.

Reinstalling the system - great way remove "viruses". As a rule, Windows 10 is distributed bundled with laptops or compatible devices, where installed a large number of programs. They only take up space on your hard drive and weaken computing power devices.

In any case, you need to reinstall the OS.

To ensure the reinstallation goes smoothly, it is important to prepare the following:

Reinstallation is not that different from normal installation. Put the items listed above in one place so you don’t have to search for them in the future.

Requirements for reinstalling Windows 10

Surely you want to install the system on a laptop/PC without an OS or upgrade from Windows 7/8.1. Whatever the reason, you need to comply with the requirements for Windows 10. Make sure that the system meets the minimum standards.

Otherwise, reinstallation will not work:

0 GHz processor or faster;
1 GB RAM for 32-bit systems and 2 GB RAM for 64-bit systems;
minimum 16 GB free space on the hard drive;
broadband or wireless Internet(3 Mbit/s recommended);
video card supporting DirectX 9 or higher;
Microsoft account.

Questions regarding reinstallation

Before installation, you may have several questions:

I upgraded from Windows 7/8 for free. Is it possible to reinstall the system?
Do I still need a product key?
Can I still reactivate the OS?

If you were able to update your system to latest version free, then you can still reinstall it. At Windows registration will still be recognized by Microsoft.

During activation in offline mode you only need the product key. When connected to Windows network 10 will register without your participation. This will not work if the key is not purchased.

Reactivation is also an automatic process. However, if you have made changes to the hardware, such as adding a new motherboard, then the version may not be valid.

Important! Before reinstalling your operating system, make sure you have backed up all your files and data (if possible).

Reinstalling Windows 10 from a USB flash drive

Previously installation operating systems was made from disk. Nowadays a popular method is using a bootable USB flash drive. To do this, you will need a compatible USB drive with Windows 10 optimized on it.

It is important to note that simply installing Windows 10 on USB device not enough. At loading BIOS Before actual installation, the system must be prepared and recognized.

You can also create installation disk, but for now we'll focus on the USB drive.

Creating an installation USB drive

Step 1. First, you will need to download the system image from the Microsoft website. But one ISO file not enough. In order for the computer to recognize and boot the system, you need to create an installation flash drive.

Step 2. To do this, download the Windows 10 ISO file and also Windows tool 10 Media Creation Tool.

Step 3. Connect the USB drive to the device you want to use for reinstallation.

Important! Make sure the flash drive has enough space (about 8GB is recommended).

Step 4. Launch Media Creation Tool.

Important! All data on the flash drive will be deleted, so it is better to use a new or empty one.

You will be presented with several options: one regarding the update, and the other - USB preparation. Click "Create installation media (USB flash drive, DVD, or ISO)."
Click on “Create installation media (USB flash drive, DVD or ISO)”, click “Next”
Then decide on the version (64-bit or 32-bit) and system language.
Next, select the USB drive connected to your computer. Once the process is complete, the tool will automatically select the options that suit you.
In the new window, select the device "USB Flash Memory Device".
First, all files will be downloaded, and then the process of unpacking and creating a bootable USB flash drive will begin. The image download time depends on your Internet speed.

It's time to reinstall Windows 10

Step 1. You will need to boot from a USB drive. To do this, make sure it is connected. Restart (or turn on) the system you want to reinstall. To do this, go to the BIOS. To get there, quickly press the F8 key or one of the keys offered during boot (F12, F10, F2). Typically, it can be found at the bottom of the screen. The number depends on the motherboard.

Step 2. After this it will open BIOS screen. Again, depending on the motherboard and technical characteristics equipment, it may vary slightly. However, all BIOS are characterized by Common parameters kernels:

Step 3. Depending on your setting, you will see a number of options. For example, when Windows installation 10 on brand new hardware, you will be prompted to enter a registration key. However, since we are reinstalling the system, we must select “I don’t have a product key.” Activation will occur after installing the OS.

Step 4. During installation, you will see several screens where you need to select the correct options. When a window appears asking you to select the installation type, click “Custom”. This is done because we are not updating, but completely reinstalling the system.

Step 5. You will then be able to select the primary partition where Windows will be installed. Let's say you want to overwrite and delete all previous data. Hence, format the current partition.

Step 6. The installation process will continue until the login screen appears. If you created a password, enter it now. If not, you will be taken to the main desktop.

Step 7 When connected to Internet Windows 10 should register automatically. Otherwise, you will have to enter your product key when prompted. If you have already done this before, but cannot activate the system, it means that you installed it with incorrect settings or changed the assigned hardware such as the motherboard.

Step 8 If version Windows is correct(Pro or Home) and there are no problems, but it is not activated yet, perhaps Microsoft servers are busy. To solve the problem, try restarting the device (we recommend checking if the download is stuck).

Step 9 If you are still unable to activate Windows 10, either due to an error or other hardware issue, then contact Microsoft support for assistance.

Important! You can also activate using next command on the command line (leave the parentheses): “slmgr.vbs/ato”. It restarts the activation request, asking for a product key and stuff like that.

Congratulations! You have successfully reinstalled the OS using a USB flash drive as bootable media.
