Windows 10 risk of reinstallation on laptop. Reinstall Windows without disk and flash drive. Preparing a bootable USB drive

If your version of Windows 10 brings a lot of problems, certain components of the system do not work, or the changes made interfere with normal work on the computer, then it's time to reinstall the operating system. This quick guide will show you how quickly and easily you can reinstall Windows 10 on your computer or laptop.

Consider a program that was installed on a computer along with the Windows 10 Anniversary Update. It allows you to easily and conveniently reinstall the system - without the need to perform additional steps. We will also consider the option of reinstalling the "dozens" if you are not using the Windows 10 Anniversary Update.

Before proceeding to reinstall Windows 10 on your computer or laptop, you need to make a back-up copy of the system. Even if you are not planning to fully format the disk, this procedure can be very helpful. Especially if something goes wrong during the reinstallation process. The backed up copy can be saved to an external hard drive or transferred to cloud storage (Dropbox, Google Drive, Box.com, OneDrive, etc.).

Self-service installation of Windows 10

The main way that it is better to use to reinstall Windows 10 on a computer or laptop is to create a bootable installation disk and reinstall the operating system from it. But, before proceeding with the reinstallation, do not forget to write down your Windows 10 version key. If you do not know how to find your Windows 10 product key, see below.

First, install the official free Microsoft program - Media Creation Tool on your computer. This application is designed to download and update tens. After launching it, we start boot Windows 10 to your computer, mark that the system is booted in ISO format, which will then burn to a DVD disc. To do this, check the "Create an installation disk for another computer" item.

After burning the ISO image to CD, start the computer from the bootable disc and reinstall the system. During installation, you can select options - update installed version or install the system from scratch. If you choose the latter option, you will have to re-enter the activation key.

Refresh Windows Tool

If you have the latest update installed - that is, Windows 10 Anniversary Update, you can use the system tool to update and restore your OS.

The Refresh Windows Tool offers an easy way to reset Windows installations 10 on a computer / laptop. After launching the Refresh Windows Tool, options for further actions will appear.

During installation, you can specify whether you want to keep all data on your computer or completely clean up the disk and install the operating system from scratch. Reinstallation can take several minutes or more, depending on which option is selected, if you do not need to re-enter your product key.

Return to initial settings

You can also use a tool that allows you - as in smartphones - to return Windows 10 to its original settings. That is, reset all system settings to their initial values, and all files and documents will remain intact. This method can be used if something stops working in the OS. But if the system is badly damaged, it is better to reinstall it from scratch.

This tool is built into the Settings section, which can be accessed through the Start menu or by using the Win + I keyboard shortcut.

After opening the Options section, go to the Updates tab, and then open the "Recovery" tab from the menu on the left side. Here if the latest is set Windows update 10, there should be a section "Resetting computer settings to the initial state". Press the button "Start" and after entering the password, all settings will be deleted.

Sooner or later, the operating room Windows system have to be reinstalled. Even if you use a reliable antivirus and watch what you run on your computer, reinstalling Windows is still inevitable. In this article, we will walk you through the process of reinstalling Windows 10.

The whole process of reinstalling Windows 10 can be broken down into several steps:

  • creating a bootable disk (if you don't have one);
  • boot the computer from the Windows 10 disk;
  • the process of reinstalling Windows itself.

Create a boot disk to reinstall Windows 10

In order to reinstall Windows 10, you need a boot disk with this operating system. If you already have such a disc, you can skip this step.

So, in order to prepare a boot disk, you need two things:

  • Windows 10 disk image in ISO format;
  • a program for recording disc images;

Once you get into the BIOS settings, you need to go to the BOOT section.

And then go to the subsection responsible for the boot order. This section is usually called "Boot Device Priority".

Next, you will see a list of three or more items: 1st Boot Device, 2nd Boot Device, 3rd Boot Device, and so on. Opposite each of the items will indicate which device is being loaded at this stage.

We want to boot from disk first. Therefore, here you need to open the 1st Boot Device item and change its value to CDROM.

After that, you can save the settings and exit the BIOS. In most cases, this can be done by pressing the F10 key.

We press any key and wait until the installer appears on the screen, with which we can start.

Reinstall Windows 10

The next step is directly reinstalling Windows 10. After booting from the disk, a window with a choice of regional settings should appear on the screen. Here you need to specify the language of the operating system that you want to get after reinstallation, as well as the time format and keyboard layout. After selecting these options, click on the Next button.

The next step is choosing the installation method: or full installation. If you are reinstalling Windows 10 from scratch, then you need to choose the second option. If you are upgrading from an older version of Windows to Windows 10, then choose the first option accordingly.

Next, a window with a list of partitions on your hard drive will open in front of you. If you are reinstalling, then you should already have at least two partitions. Select the one on which the operating system is installed and click on the "Format" button.

After formatting, click on the "Next" button. In this case, at the moment of clicking on the "Next" button, the section that we have just formatted should be highlighted.

Next, a window will appear informing you about copying files. Wait a moment while the installer copies the files and restarts your computer. After rebooting, the screen will again display the message "Press any key to boot from CD or DVD", but in this case, you do not need to press anything. Just wait for the computer to boot itself.

After the computer boots up, the initial setup window appears on the screen. Here you can select "Use express settings" and "Customize". If you use the "Use express settings" option, then the system will apply the standard settings and will not ask unnecessary questions. If you choose "Customize", then you can configure everything manually. We will choose "Use express settings" as this will be fine for most users.

After clicking on the "Use express settings" button, you will see a form for entering your Microsoft account login and password. Since you are reinstalling Windows 10, you should already have this account. Enter your username and password and click on the "Next" button. If you don't have an account, then you can register it. To do this, click on the link "Create a new account".

After entering your username and password, you will be prompted to protect your account. You can skip this step by clicking on the link “I can’t do this right now”.

And after a few minutes, a worker will open in front of you. Windows table 10.

That's it, this completes the reinstallation of Windows 10. You can start installing the necessary programs and configuring the system.

Windows 10 is the best version of Windows, but that doesn't mean it doesn't get slower over time. Any Windows, for that matter, starts to work not as we wanted, there are delays, universal applications may not work, all this happens for a number of reasons, one of which is the time since the last installation or update of the system. The best way The solution to this problem is to reinstall the operating system.

Automatic activation of Windows 10 after reinstallation

Many users who have updated Windows 7, 8.1 to Windows 10 using a free update often ask if activation will fail after reinstallation, how to reinstall Windows 10 without losing the activation license, or how to activate Windows 10 again after a fresh installation.

Reinstall Windows 10 without losing your activation license

After the release of Windows 10, back in 2015, Microsoft assured that it is possible to reinstall and activate Windows 10 after a fresh installation without any problems, as long as you install Windows 10 on the same computer without major hardware changes.

Link Windows 10 license to Microsoft account

If you sign in to Windows 10 with a Microsoft account (version 1607 or later), Windows 10 automatically associates your Windows 10 license with your Microsoft account. makes it easy to activate your copy of Windows 10 when you reinstall or fresh install.

In fact, there is even an activation troubleshooter that you can use to activate Windows 10 if your copy of Windows 10 doesn't automatically activate after making changes to your PC's hardware.

Users using local account can also reinstall Windows 10 without losing license, activation. There are no tools to back up your Windows 10 license. In fact, you don't need to back up your license if you have an activated copy of Windows 10.

Activation after a fresh install of Windows 10

You can reinstall the same version of Windows 10 on the same PC (where you have an activated copy of Windows 10) without requiring you to enter your product key. When reinstalling Windows 10, if you see a prompt for your product key, just click the Skip button. Windows 10 will automatically activate once the computer is connected to the network after the installation is complete.

Before proceeding with reinstalling Windows 10, we advise you to go to OptionsUpdates and securityActivation, and check the activation status of Windows 10.

Here you will see a message "Windows is activated with a digital license associated with your Microsoft account" if your copy of Windows 10 is activated and linked to your Microsoft account (automatically if you use a Microsoft account to sign in to Windows 10). If you are using a local account, you will see the message "Windows activated with digital license".

No matter how advanced is considered "ten", sooner or later, and she begins to treacherously slow down. In this article, we walk you through the steps on how to reinstall Windows 10 on a laptop or PC with minimal hassle. We promise: even inexperienced users will cope without any problems.

1 Which is better: reinstallation, system optimization or recovery?

The good news is that Windows 10 has advanced recovery mechanisms built in, about which not everyone knows yet. And in vain. Because often you can do without a full reinstallation - the system can be returned to the state "as it was at the very beginning" in a few clicks (more on this below).

And most importantly: before resorting to any radical methods, we strongly recommend that you try our instruction "How to speed up your computer on Windows 10". In it, we have collected the most effective optimization methods that will help you thoroughly clean and overclock your system. Often this is enough - and you always have time to reinstall Windows!

2 OS recovery instead of reinstallation.

2.1 How to reset a computer to its original state on Windows 10.

So, the promised "life hack". Not everyone knows that instead of a long and painful reinstallation of Windows 10, you can quickly return the OS to its original clean state by resetting it to factory settings.

It's like a regular reinstallation, it only saves a lot of time and hassle. You can even choose whether to erase everything or keep your personal files.

Although the installed software and OS settings will still be removed. Therefore, it is best to prepare in advance a list of programs that will need to be installed again after the end.

Windows 10 refund is made to the initial state is very simple.


That's all! After a few minutes, the system will return to its original state - as on the day of installation. It may well be that you won't have to reinstall anything. Try it.

Because of some problems, the "ten" refuses to load? You can still roll it back to its original settings (in the process, the errors that caused the problems will also be erased). How? After several unsuccessful attempts to start, the OS will throw you into the boot menu. In it, select "Return the computer to its original state" and follow the steps described above.

2.2 How to downgrade to a previous version of Windows 10.

After the next update, the "ten" began to work poorly? Fortunately, there is no point in fiddling with reinstalling Windows 10 from scratch either - over a period of time, the OS can be easily rolled back to the previous build.

For this:


3 How to reinstall Windows 10 from a USB flash drive.

We decided to completely demolish and move the OS to the laptop again? Our step-by-step instruction reinstalling Windows 10 from a USB stick will make this task as easy as possible.

  1. Because all information from disk C will be erased, all important files from it will be transferred to a safe place: to disk D or a USB flash drive. Don't forget to check "Desktop", "My documents", "Downloads" etc.
  2. Remember how big the drive was WITH and how much free space on it - this will come in handy later, when you need to "recognize" it during the installation process.

3.1 Preparing a bootable USB stick.

Before, how to reinstall Windows 10 from a USB flash drive, this installation USB needs to be created first. What is the easiest way to do this?

  • Need a license? Then you can stop reinventing the wheel and use the Media Creation Tool - the official utility from Microsoft. She will do almost everything herself: she will download Win 10 and write it to a USB flash drive. We just download the program itself, open it and follow the simple instructions on the screen.
  • You are not particularly interested in the license, but did you somehow get hold of the cherished ISO image of the "10"? Writing it to a USB flash drive will help command line or any of the free utilities - UltraISO, WinSetupFromUSB, USB / DVD Download Tool, WinToBootic, Rufus, etc.

In order not to repeat ourselves, we invite you to take a look at our article "How to create a bootable USB flash drive for reinstalling Windows 10". There we described in detail 8 recording methods - both for the license and for unofficial versions.

Which version to choose - 32-bit or 64-bit? Depends on volume random access memory... If you have up to 4 GB - use 32-bit, if more - feel free to take 64-bit.

3.2 Starting installation via BIOS / Boot Menu.

To start reinstalling Windows 10, you need to set the boot from a USB flash drive. We insert the drive into the USB port, reboot, and then there are 2 options.

1) Simplest- go to the boot menu ( Boot Menu) and use the up and down keys to select boot from our USB stick. Here is a plate with buttons that call the Boot Menu on different computers (click immediately after restarting, as soon as a black screen appears).

Desktops

  • MSI (motherboard) - AMI (BIOS) - F11
  • Gigabyte - Award - F12
  • BioStar - Phoenix-Award - F9
  • Asus - AMI - F8
  • Intel - Phoenix-Award - Esc
  • AsRock - AMI - F11
  • ChainTech - missing
  • ECS - AMI - F11
  • FoxConn - Esc
  • GigaByte - F12

Laptops


2) Second way a little longer - instead of the Boot Menu, we enter the BIOS (the keys to enter here - link) and in the list of boot devices we assign our first USB flash drive to the first. For this:


You will have your own exact names, but in general the line with "USB" should get higher than "HDD / Hard Drive".

Made? Great, the following message appears most often after loading:

Press any key and the reinstallation of Windows 10 has officially begun!

3.3 How to reinstall Windows 10: select the version / bit.

We have briefly described this step in steps.

Window No. 1: Select all "Russian"(language, time format, layout).

Window No. 2: Click "Install".

Window No. 3: If there is an official key, then enter it. If not, at the bottom we honestly click on the blue inscription: "I don't have a product key".

Window No. 4: (The window appears if there are 2 versions of Win 10 with different architectures on the flash drive at once)

We indicate the one that we are going to install.

Window No. 5: Choose between Home and Pro versions (we recommend "Home").

(This window does not always exist)

Window No. 6: We read the license agreement, tick the consent box, click "Further".

Window No. 7: Click on the second option " Custom: Windows Install Only "

3.4 Partitioning / formatting the hard drive.

At this step, we get to the menu where we have to select the partition of the hard drive for reinstalling Windows 10. Do not worry if there are an order of magnitude more disks than you are used to seeing: now we will figure it out.

Remember how we wrote down the dimensions of the disk WITH before starting the installation? So we can easily define it: find, choose, press "Format"(at this stage it will be completely cleared), select again and click "Further".

If you want (for example, on the "old" disk C not enough space), you can partition your hard drive in a new way. To do this, select all the current sections, click "Delete" and the key "Create" set new ones. Then select the disk for installation and click "Further".

In terms of free space on Windows disk 10 is pretty gluttonous. To be sure, target 20-25 GB for 64-bit and 16-20 GB for 32-bit. Microsoft modestly names the minimum figures, but in real life they "swell" almost instantly.

Sometimes it is necessary to additionally install a second OS on the computer without touching the current one. How do I reinstall Windows 10 while keeping the old version? Nothing complicated: we put a new one on a neighboring disk (for example, on D), and we get two autonomous systems. The entrance to the desired one is selected at each start.

  • We decided on the section and clicked "Further"? The files will be copied to it and the computer will restart.
  • At this stage, quickly take out the USB flash drive (if the installation window from the USB flash drive still managed to appear again, just close it and the system will restart again, this time as it should)
  • For a while we admire the black screen with the ten logo and the message "Preparation in progress" while the system is preparing, configuring, etc. Sometimes the computer will restart itself, sometimes it flickers or freezes - everything is fine, we do not touch anything. As a rule, the whole process of reinstalling Windows 10 takes about 30-100 minutes.
  • Finally, the system will ask us to enter the key. At the bottom left, you can click on the small inscription "Do it later".
  • Then we choose whether to connect to the Internet via Wi-Fi (if you plan to immediately log into your Microsoft account, connect, if not, while you can choose "Skip this step").

3.5 Configuring parameters and account.

Now let's start configuring the parameters. If you don't want to mess around now, just click "Use standard parameters"... All this can be changed after you reinstall Windows 10, already in the process.

If you do not mind solving the issue immediately, then click "Settings" and follow these steps:


In the next step, if the computer is connected to the Internet, the system will invite you to log in to your Microsoft account. But in order to avoid some potential glitches, we recommend that you do this after the installation is complete. In the meantime, it's better to choose "Skip this step"(small blue lettering at the bottom).

We get to the menu for creating a local account (if there is no Internet, then you will be transferred here immediately, without the previous window).

Everything is simple here: we come up with a login / enter the password twice / click "Next". If you don't want to, you can leave the password blank - then Windows will not ask you for it when you log in. But it's better to put it.

We are approaching the finish line! At this stage of reinstalling Windows 10, it independently deals with various fine-tuning, installs all sorts of programs, etc. We can only contemplate the encouraging screen "It may take a few minutes."

But do not rush to take his word for it: if the computer is not very powerful, in practice, all this can drag on for a good half hour. We do not touch anything, do not turn off, do not reboot - we just go about our business and wait.

When the system finishes everything, you will see the desktop of the brand new Windows 10.

3.6 Installing drivers and programs.

That's all, we have successfully reinstalled Windows 10. It remains only to install the necessary programs and drivers. In principle, if a laptop or PC is connected to the Internet, the “dozen” selects and installs the drivers themselves, but most often they do it not very well.

It's best to rearrange them manually - it's pretty quick.

  • On a PC: we drive the manufacturer's official website into the search motherboard and download everything there.
  • On a laptop: go to the manufacturer's official website, in the "support" column we find our model and drivers for it.
  • Where can I find drivers for a video card? Depending on the model, we go to the site AMD, NVIDIA or Intel.

4 After reinstalling Windows 10, the computer does not start, what should I do?

Did you do everything according to the instructions, but the system refuses to start? Don't panic.

If you see a blue screen with captions, check out our article "What To Do If A Blue Screen Of Death (BSOD) Appears?"

  1. In 90% of cases, the problem turns out to be a conflict of the video adapter driver: try booting in safe mode and uninstalling the driver (to load safe mode, you will have to barbarously shut down the computer with the button).
  2. Also check if the computer is connected to 2 monitors at the same time? If yes, then remove the 2nd, and disconnect the 1st from the discrete video card and reconnect to the built-in one.

90% chance that after completing the first or second point, everything will work.

As you can see, reinstalling Windows 10 was not that difficult.

Here are all the steps you need to take when reinstalling Windows 10 from a USB flash drive. There is nothing complicated in them: the eyes are afraid, but the hands are doing!

Tell us in the comments, did you get it right the first time? Was there anything incomprehensible? Or maybe you have any "pitfalls" that are not described here? We will try to take into account all your questions and supplement the article.

Installing each new release of Windows is easier than the previous one and requires less user effort. With the release of Windows 10, this task has become easier than ever: now, in order to install an operating system on a computer, you do not need any special knowledge and ingenious applications. You don't even need a Windows distribution kit - the installer "learned" to download it itself. She herself creates installation media - a DVD or a USB flash drive. The user only has to respond to requests and follow instructions that are understandable even for those who do it for the first time.

Today we'll show you how to do a clean install of Windows 10 on any laptop and desktop PC. A clean install is an OS installation on media that does not have an operating system (for example, on a new computer or formatted hard drive). Or where it is, but it must be completely overwritten without saving the installed software, accounts and settings. By the way, don't worry about the license: if you install a system instead of a legally activated one, you can save it. And we will not hide from you what needs to be done for this.

What do you need

  • Bootable media for recording the Windows 10 distribution kit. It can be a USB flash drive with 3 GB or more, a DVD drive, a portable or internal hard drive. Since the vast majority of users prefer to install Windows from a USB flash drive, consider this method as the main one.
  • or a set of files.
  • Transfer utility system files to the installation media. If you are going to install Windows 10 on a PC with UEFI (advanced "BIOS"), you can do without it - you just need to copy the files and folders of the distribution to a USB flash drive. By the way, in Windows 8 and 10, the ISO image can be opened in Explorer as a regular folder, but in earlier systems this will require a special application, for example, any archiving program.
  • The computer on which you will prepare the bootable USB flash drive.

Cooking a USB flash drive

If you do not have a pre-prepared distribution kit of "tens", it is easier and more convenient to instruct it to download the Microsoft Media Creation Tools utility and use it to burn it to a USB flash drive or DVD.

The utility does not require installation on a PC, it is enough to run it with administrator rights.

After launching Media Creation Tools:

  • In the "License Terms" window, click "Accept".

  • To the question "What do you want to do?" we answer: "Create media for another computer."

  • In the "Selecting options" section, define the system language, edition ("home for one PC" or "Windows 10") and architecture (bitness) - 64 or 32. If the selection options are grayed out, the "Use recommended settings" checkbox should be unchecked.

  • Next, select the drive: USB - to create a bootable flash drive, or an ISO file - to upload an image that you will burn to DVD in the future.

  • After selecting the USB device, click "Next" and wait 30-50 minutes while the program downloads the distribution kit and creates the installation media. At this time, the computer is available for use.

  • You will be informed that it is time to proceed with the installation by the message: "The USB flash drive is ready."

If you downloaded the distribution in advance or do not have stable Internet access, use other tools to create Windows 10 installation media. For example:

  • Rufus. Works without installation. To write an operating system to a USB flash drive, it is enough to specify the location of the distribution kit, as well as determine the partition scheme and the type of system interface: MBR for computers with BIOS (old), GPT for computers with UEFI (new, released after 2013) or MBR for computers with UEFI ( if your UEFI PC has MBR-formatted disks).

  • ... This utility is as simple as Rufus. In the "Add to USB disk" section, it is enough to mark the item "Windows Vista / 7/8/10, etc.", specify the path to the Vinodovs 10 image and click the "Go" button.

  • Windows 7 USB / DVD Download Tool. This proprietary Microsoft utility is capable of transferring all versions of Windows, starting with the "seven", to USB-flash drives and DVD-drives, in just 4 steps.

In addition to these, there are tons of other free utilities for creating installation media. You can use any - the result will be the same.

We start the installation

Installation launch options

Windows 10 installation can be started in two ways:

  • From under a running system. It can be used if you plan to reinstall it or install the top ten from scratch to another partition of the disk.
  • When booting from the installation media (via BIOS). A universal option that is suitable for installing the system on a new computer, and for reinstalling an old copy of Windows.

If you choose the first option, open the boot disk or USB flash drive in Explorer and run the Setup.exe file.

If you choose the latter, boot your computer from the installation media.

How to boot a PC or laptop from a USB flash drive

The BIOS Setup utility has a different interface on different computers. To enter it, you must press a certain key immediately after turning on the machine and the manufacturer's splash screen appears on the screen. Which one is usually indicated at the bottom of the splash screen. Most often these are Delete, F2 and Escape, sometimes F1, F3, F10, F12, or a combination of several keys.

Once the utility is open, navigate to the Boot section. In the BIOS Setup Utility version shown in the screenshot, this is a separate tab in the top menu.

In other versions, it does not exist as such, and the necessary settings are collected in the "Advanced Bios Features" section. In order not to confuse anything at the most crucial moment, study in advance the BIOS interface of your computer and figure out what and where is.

In the "Boot" section, you will see a list of devices from which the machine can boot. The first place is usually the hard drive. You need to make sure that the computer first checks the boot files not on it, but on the USB flash drive. To do this, using the arrow keys, as well as F5, F6, plus and minus (the tip is located in the right half of the BIOS window), lift the USB device to the top of the list. Press F10 to save the setting and exit the utility.

In graphical versions of UEFI, you do not need to change the order of devices, just click on the USB device. After that, the PC will restart and start booting from the selected media.

The main part of the installation

Most of the Windows 10 installation process takes place without the active participation of the user. You will have to work only at the beginning and a little at the end.

So, the first thing you have to do is choose the operating system language, time formats, currency formats and the main keyboard layout. If you downloaded the Russian-language version of Windows, the default language will be Russian.

After defining the language settings, click the "Install" button.

Accept the license terms. To go to the next task now and in the future, click the "Next" button.

The next step is to define the type of installation - upgrade or custom (in previous versions it was called clean). We, accordingly, need the second type.

Let's move on to choosing a place to "settle" new windows... If the hard disk is not partitioned or you want to change their aspect ratio, select the required area of ​​the disk and click "Create".

In the "Size" field, specify the number of megabytes that you allocate for the system partition. 64-bit Windows 10 requires at least 32 GB. Click Apply. If necessary, create other partitions in the same way, and then format them.

Attention! If you want to install the system while maintaining the license, do not format the disk, but carry out the installation in the same partition where the previous - activated copy of Windows is located. The second important factor in maintaining activation is that the new system must be the same version as the old one. If you install Windows 10 Ultimate instead of Home, you can't do without losing your license!

After finishing work with the disc, you can relax - for the next 40-60 minutes the process will go on without your participation. If you want, just watch him.

It will take about 1/4 of the time to copy the files.

The computer will then reboot and continue with the installation. Most of the time, the Windows logo will hang on the screen and the "wheel" will rotate. You can understand at what stage the process is by the messages at the bottom of the screen.

It's time to get back to active action, because the end of the installation is nearing. When you see an offer to increase the speed of work, click the "Use standard parameters" button. You can change them later if you wish.

After the upgrade, you will need to create the first user account. By default, it will be assigned administrative rights. Everything is simple here - enter a username and enter a password, if necessary.

Finally - the long-awaited desktop. Everything is ready, the installation of Windows 10 is complete. We hope it did not bore you too much, because now you have to set up the network, design the desktop, install applications and other pleasant chores to "settle down" the new OS.

If during the installation Windows did not require you to enter a license key, check if the activation is in place. Open the context menu of the "Start" button and go to the system settings.

Activation information is located at the bottom of the Basic Computer Information window. In our example, it was not executed, since "ten" was installed in the virtual machine from scratch.

If you succeeded in reinstalling the license, you can delete the C: \ Windows.old folder, which contains the files of the previous copy of the system. They are no longer needed - the activation information has been successfully migrated to the new one.

How to install a system from a hard drive

There are situations when neither flash drives nor DVDs are at hand. In short, nothing but the hard drive of the same computer on which you need to install Windows 10.

To install "tens" from a hard drive, you must meet 3 conditions:

  • Have a distribution kit. More convenient - in the form of a set of files and folders. If you only have an ISO image, you will have to unpack it, for example, using an archiving application (WinRAR, 7-zip and analogs) or Windows explorer(only in the "eight" and "ten").
  • Have an additional partition on a hard disk with a capacity of 3 GB or more. Desirable free.
  • The computer must boot from the same disk. If not, you will need a Live CD / Live USB (portable operating system) media such as BartPE, Alkid Live CD, etc. You can easily find their images on the net.

The hard disk, or rather, its additional partition, will serve as the carrier of the installation files. Operating system you will need to copy the distribution and create its bootloader.

Installation procedure

  • Boot your computer from a hard drive or portable OS media.
  • Copy files and folders of Windows 10 distribution to root additional section(not the one where the system will be installed).

  • Rename the boot file (bootmgr), for example, "Win10". The length of his name must not exceed 5 characters.

Now you have to create a bootloader for the distribution using the BootICE utility. You can use other boot management tools instead, but we chose BootICE because we find it the simplest and most convenient tool.

  • Run the utility (it does not require installation). In the "Physical disk" section, select the hard drive of your computer from the "Destination disc" list. Click the Process MBR button.

  • Check Grub4DOS and click Install / Config.

  • In the "Rename GRLDR" section, write the new name of the Windows 10 boot file (as you remember, we named it "Win10") and click "Save to disk". Click OK on the message that the bootloader was successfully created and close the utility.

It remains to restart the computer. At the next start, the Windows 10 setup program will receive control, and then it will be the same as when installing the system from a USB flash drive.
