And accordingly, you do not have recovery points. In this case, reinstalling Windows 7 is the only way out, unless, of course, you have or do not want to restore the system from an image made, for example, using the built-in backup system. In this article we will try to describe in as much detail as possible how to install Windows 7.

You can read how to burn an image to disk using Ashampoo. The image itself can be downloaded from almost any torrent tracker. If you need original Windows 7 images, please read. You can read how to download from a torrent. Information about will also be useful.

Setting up BIOS to reinstall Windows 7

We have already covered this issue when installing Windows XP with and with . Let's not be lazy and repeat.

First, let's go into the BIOS by pressing one of the DEL, F2, F10 or Esc keys during boot. If you try these keys and nothing happens, refer to the instructions or.

At the bottom of the main window, you can (BIOS of the P8H67-V motherboard) by moving the corresponding icons to the left or to the right. Select the optical drive icon and move it to the left, in front or.

You can also configure the loading order in advanced mode on the tab Boot. In line Boot Option #1

Next, set the operating mode or to ACHI. The mode allows you to use NCQ - hardware command queuing, which in turn speeds up the operation of the drive. Go to the tab Advanced. .

The settings will be saved and the computer will restart.

Reinstalling Windows 7

Insert the burned disc with the image and reboot. The following picture will appear asking you to press any key. If booting does not occur, it means either the disk is bad, or the drive cannot read it, or the BIOS is not configured correctly. We check everything again and boot from the installation disk.

Next, you can configure or (convenient for new drives). Function Create- allows. If you are setting up a new disk, then when you create the first partition, the system will create a 100 MB service partition. It is better to choose the size of the system disk (on which you will install Windows 7) from 20 GB or more, depending on the version and bit depth of the operating system. It seems to me that for 64-bit operating systems, it is advisable to allocate 60 - 100 GB to the system partition, so that you can install the necessary programs and allocate enough space (10-15%). + space required for the swap file is 1.5RAM and for hibernation or sleep mode - 0.75RAM and it is advisable to leave at least a little for documents. 100 GB will be optimal.

If several people work at the computer, then my partitioning policy is as follows: system partition 100-200 GB (200 since they will store documents on drive C); and one general section with movies, photos and other media content, all the remaining space. Also, when creating a non-system partition, there is a format function, the use of which seems more rational than doing it in the installed system. We partition the disk according to your requirements and click Further. You can read how to partition a hard drive on an already installed Windows 7 operating system.

Conclusion

In this article we looked in detail at how it is done reinstalling windows 7 on the computer. Let's repeat the main points:

• download and
• setup for BIOS installation
• setting up the computer drive for installation
• Windows 7 installation
• driver installation

The installation process may vary slightly, but the principle is the same.

It is important to install drivers correctly so that there are no unknown devices, and only after that proceed to installing browsers, etc. If you have questions about driver removal, please look.

After installing the brand new Windows 7, you can start.

If you still have or have any questions, I will be glad to answer them in the comments.

In accordance with Microsoft documentation, it is worth reinstalling the operating system at least once a year - it is in this mode that the maximum performance of the personal computer is maintained. When reinstalling, the hard drive is checked for bad sectors, defragmented, and all system services are rolled back to their original state. In other words, reinstallation is a way to throw away software “garbage”.

Windows, in addition to versions, are divided into editions within each individual version. There are six variations for Windows 7:

Description of options	Starter	Home Basic	Home Premium	Professional	Ultimate	Enterprise
Release of updates	Will last until 2020	Will last until 2020	Will last until 2020	Will last until 2020	Will last until 2020	Will last until 2020
Bit size 32 (x86)	Available	Available	Available	Available	Available	Available
Bit size 64	Absent	Available	Available	Available	Available	Available
Maximum installed RAM available for use in a software environment	2 GB	8 GB	16 GB	192 GB	192 GB	192 GB
Ability to create a "Home Group"	Absent	Absent	Available	Available	Available	Available
Ability to use multiple monitors simultaneously	Absent	Available	Available	Available	Available	Available
Possibility of adding to the domain	Absent	Absent	Absent	Available	Available	Available

When initially choosing an operating system, you should decide on the use of a personal computer. As can be seen from the table, the “Starter” version will not give you the opportunity to enjoy programs that are hardware-demanding. Or, for example, “Home Basic” is limited when working in local area networks. Moreover, the more capabilities a system has, the proportionally more expensive it is.

Important! According to corporate policyMicrosoft, selling out-of-date products is prohibited. If you are offered to buy a license key for the operating systemWindows 7 after October 26, 2012, you should know that this is illegal and falls under the articles of the criminal (146,180) and civil (more than 40 articles of Chapter 70) codes, as well as the Code of Administrative Offenses (7.12). You, as the buyer, may be held liable for being an accessory. Use only previously purchased keys.

Before reinstallation, save all data on backup media (hard drives excluding the system drive, flash card, CD/DVD), since reinstallation with full formatting of the hard drive is considered correct. Do not forget to prepare in advance all the necessary drivers that match the hardware of your personal computer. In addition to technical reserves, it is worth having an operational reserve, that is, duplicating all keys to software products, logins and passwords for websites.

Preparation - working with BIOS

Step 1. To reinstall Windows 7, you must set the primary boot device or bootable flash card. You can change the boot priority through the BIOS.

On a note! It is best to use the official distribution kits of the corporationMicrosoft, however, under the license agreement, you can use their copies (no more than two for each paid license), including recording the distribution image on a flash card.

Step 2. The boot order is regulated through the “Boot” menu item.

Step 3. In the list of menu subsections you need to select “Boot Device Priority” (boot device priority).

Step 4. Select the line that indicates your optical drive or flash card. Do not forget to disconnect all flash cards from the computer except the one from which the installation is to be carried out.

Important! When using an external drive or flash card to reinstall the system, do not forget that they must be connected to the computer before loading the BIOS. If there was no connection, the devices will not be displayed, in which case you should restart your station and enter the BIOS again. When searching for a device to boot, focus on its model, and not on the BIOS designation - for example, externalThe DVD drive may be designated asCD.

Step 5. Change the boot order using the Change Values ​​keys.

On a note! In this BIOS version, these keys are “F5" and "F6", however, it can be “+” and “-”, or others. Look carefully at the help window at the bottom of the screen.

Step 6. To apply the new settings and restart the computer, use the “F10” key, or the “Save changes and exit” menu.

System reinstallation

Step 1. On the first page of the installation wizard you will be asked to specify the operating system language and default keyboard language.

On a note! Even when installing the English versionWindows, you should specify the Russian keyboard layout. The fact is that the English layout is integrated into any version, edition and build of the operating system. If the Russian layout is not specified as the default one, then for its further installation you will have to sequentially download system updates, install them in a certain sequence, and register Russian character tables in the registry.

Step 2. To continue, use the “Install Now” button.

Step 3. Please read the license agreement carefully. In order to accept it, click on the consent option and click “Next”. If you refuse to accept the agreement, the installation will stop.

Step 4. For proper reinstallation, it is necessary at this stage to use the “Custom” option - using this type of installation, all work on cleaning the hard drive, restoring damaged sectors and full formatting are performed.

Step 5. The next installation wizard window prompts you to select a system hard drive. Before continuing, it is strongly recommended that you format your hard drive using the “Drive options (advanced)” list of commands.

Step 6. To start the cleaning procedure, click on the “Format” button.

On a note! UnlikeWindowsXP, inWindows 7 does not provide Quick Format technology. To completely delete all files and data, without the possibility of their subsequent recovery, you should format the hard drive at least twice in a row.

Step 7 The installer will prompt you to confirm the format procedure, to which you must agree.

Click "OK"

Step 8 At the end of the technical procedures, you must indicate the logical volume of the hard drive on which you are going to install the operating system.

Step 9. The installation wizard performs the installation in stages. There are five of them in total:

1. Copying Windows files (transferring copies of installation data to your hard drive).
2. Expanding Windows files (unzipping transferred files).
3. Installing features (installation of utilities, in other words, system services).
4. Installing updates (installation of updates contained in the distribution).
5. Completing installation (collection and removal of temporary files created in the first two stages).

Step 10

Step 11 The Setup Wizard begins preparations for the first launch of the operating system. At this stage, your participation is not required.

Step 12 When prompted by the operating system, enter your login and PC name. The first user created has the maximum possible (administrator) rights in the system.

On a note! If the personal computer is not connected to the enterprise local network (stand-alone), then the name can be selected in any language. To achieve maximum performance in the domain, use logins and computer names in Latin.

Step 13 Setting a password is optional.

On a note! Considering that the first user has full access to all computer resources, it is recommended to set a password. When working in domain networks, it is worth specifying the password in Latin, as was recommended for the login and PC name. Requirements for the length and character composition of the key are established by the enterprise system administrator. Forstand-alone machines this remark is irrelevant.

Step 14 In order to increase protection, the installation of current operating system updates is required, so at this stage you should check the “Use recommended setting” option (install all available updates automatically). If you mistakenly used another item, do not worry, the settings can be made within the installed system.

Step 15 Please enter the current time and date.

On a note! Usually these parameters are set correctly initially. If the date given is incorrect, the battery in the non-volatile memory (CMOS,CMOS) and needs to be replaced. Battery format –CR2032.

Step 16 The installation wizard will start the process of installing the entered settings.

Step 17 If necessary, you can install any language pack on the system. To do this, you should use the “Windows update” update search located in the control panel.

Step 18 Find the language you need in the list (for Russian – package KB972813) and run the installation wizard. The process takes place automatically.

Video - How to reinstall the Windows 7 operating system

Conclusion

This method of installing the operating system can be considered a “reference” method. The article reveals the sequence of correct reinstallation of the Windows 7 operating system. The final recommendation is that installing the system is not enough; you need to monitor the release of new system update packages and driver updates in order to maintain the security and performance of your computer at a high level.

You download a new Windows image from the official Microsoft website, run the installation, enter the license key from the sticker on the laptop case... and receive an ominous message that the system is already in use. How to reinstall Windows if it came with the device and you honestly paid for the license?

How to restore the system if it was preinstalled?

The problem with pre-installed Windows is that it is not Microsoft that sells it to you, but the laptop manufacturer, and in the quantity of one specific copy, for which he himself bought a license from Microsoft. The license key of this copy is often sewn directly into the laptop's BIOS. And you can restore the system with this license key only from the image of the Windows that was installed on your laptop.

Therefore, the best way to restore an OEM copy of Windows is a backup restore point created by the system itself - for example, automatically using Windows Defender.

Here's how to reinstall Windows using a restore point:

1. Download the system image from the official Microsoft website: Windows 7, Windows 8.1, Windows 10. You may need to enter a license key. Where can I get a license key if the computer was sold with a pre-installed OS? As a rule, it is applied to the laptop case or box in the form of a sticker (the so-called Certificate of Authenticity). If the sticker is lost or damaged, you can contact your computer vendor to see if they have a way to recover the key.
2. Burn the image to a CD or flash drive using a tool convenient for you - for example, UltraISO or WinSetupFromUSB.
3. Insert the disk or flash drive into the computer on which you want to reinstall Windows and boot from it, setting the BIOS to boot from a CD drive or flash drive.
4. Windows installation will start. In the installation window, select your system language and other settings and click Continue.
5. In the next window select System Restore(Troubleshooting > System Restore on Windows 10).
6. Select a system restore point. Most users will have one.
7. Wait for the recovery procedure to complete, remove the flash drive and boot from the main hard drive.

This method allows you to return Windows to a working state. In this case, a number of programs that you installed after creating a restore point may be lost, but the system will work and, most importantly, the license key will remain active.

How to reinstall Windows from an emergency recovery flash drive?

Another way to reinstall Windows without losing your license is to use a rescue disk. It must be created in advance, preferably immediately after purchasing the computer. There are several ways to do this:

• A number of computer manufacturers provide tools for creating recovery discs, for example, Samsung Recovery Solution for laptops of the same manufacturer. Check if you have such tools and use them.
• You can use the standard Windows tool - Backup and recovery (Backup and Restore in Windows 10), accessible through the Windows Control Panel. Just open the built-in utility, select WITHCreate a system repair disk, connect the USB flash drive to the computer and follow the instructions.
• You can also use third-party tools for creating system images, for example, as described in.

If you have a recovery disk, reinstalling licensed Windows is done as follows:

1. Insert the emergency recovery flash drive into the computer on which you want to reinstall Windows and boot from it.
2. The Windows Recovery Environment will launch. Select System Restore >(Troubleshooting > System Image Recovery on Windows 10).
3. Select the latest available system image and click Further to start recovery.

The system will be reinstalled from the image, but the license key will also remain valid.

These two methods are guaranteed to make it possible to reinstall Windows 10, which was pre-installed on the laptop, without losing your license. Alternatively, you can contact the computer or laptop supplier's service center under warranty: according to the terms of the agreement with Microsoft, the supplier is responsible for the operation of your system.

In this article you will learn how to reinstall Windows 7 yourself. The material is designed for users who will be installing Windows on a computer or laptop for the first time. No matter how scary it may sound, reinstalling Windows is very simple. In the days of Windows 95 and 98, to an inexperienced person, the procedure of reinstalling the operating system could seem like a mystical rite. The person who was invited to do this was necessarily called a programmer and was considered a guru in the computer field.

For their part, such gurus, inflating their value, intimidated their clients in every possible way with scary computer terms and stories about viruses and burned-out computers. In this guide, you will see that this is not at all true and that installing or reinstalling Windows on your laptop or computer is very simple and accessible to almost anyone who knows how to use a computer mouse.

I will make a small reservation. This article will tell you how to install Windows 7 yourself using a DVD. If your computer or laptop does not have a DVD drive, then you will need to install Windows from a USB flash drive or from a memory card, I will talk about this in another lesson.

Before you start reinstalling Windows, read the entire article to the end, and if you have a printer, print it out.

Reinstalling Windows 7 consists of several steps:

1. Preparing your computer for installing Windows 7;
2. Preparing an installation disk with Windows 7;
3. Setting up the computer's BIOS to boot from a DVD;
4. Installing Windows 7;

Now let's go through all the stages in detail.

1. Preparing to install Windows 7

Before reinstalling Windows, you need to do a little preparation.

First, you need to copy all the valuable information from drive C. Of course, you know better, but I’ll still tell you where to look. There are not so many places where your useful information can be located on the “C:” drive, usually the desktop and “My Documents”. It’s also worth looking at the root of the “C:” drive; sometimes people, in a hurry or simply out of ignorance, save files there. Copy all the files you need to another drive (for example, “D:”), DVD drive or flash drive.

For the future, keep in mind that it is best to store information not on the same disk partition on which the system is installed, and, of course, create backup copies.

If you just purchased a computer or are sure that there is no valuable information in it, then naturally you don’t have to bother

Another point that is worth considering before installing Windows is the drivers for the network card. If after installation it turns out that your Windows distribution did not have drivers for your network card, or for some reason they were not installed correctly, then you will find yourself without drivers and without the Internet. Therefore, download the latest drivers in advance, at least for the network card.

2. Preparing an installation disk with Windows 7

For those who already have an installation disk with Windows 7, you can skip this step. If you don’t have such a disc, then you need to burn it or purchase it. Those who want to download Windows on the Internet, look for clean MSDN builds.

This will protect you from possible errors in the operation of the installed system.

Installation disks with Windows 7 on the Internet are usually distributed in the form of disk images in the ".iso" format. I won’t say where to download because... promoting their spread is not entirely legal. I can advise you to read the release comments before downloading the image; problematic disks are usually quickly identified in the form of a bunch of angry reviews.

At this stage, you should decide which version of Windows 7 to install on your computer, 32-bit or 64-bit. I will not go into details, since a separate article can be written on this topic. I will only say that a 64-bit system can work with the entire amount of RAM, while a 32-bit system uses only about 3.25 GB at most. At the same time, a 64-bit system, thanks to 64-bit address pointers, requires more memory during operation. This increases the amount of memory consumed by applications.

Also in favor of a 64-bit system, it is worth considering that when using 64-bit applications there will be a fairly good increase in their performance.

Conclusion: a 64-bit system should be used if the amount of RAM in your computer is 4 gigabytes or more, which, in principle, is already becoming the norm for a modern computer.

After the image is downloaded, you need to burn it to a DVD disc, and you can begin installation.

3. Setting up the computer BIOS to boot from a DVD

To install Windows, it is not enough to simply insert a DVD into the drive; you also need to make sure that the computer starts booting from this disk when you turn it on. This is done in the BIOS. There is a BIOS in almost any computer or laptop; all sorts of important settings are stored in it, one of these settings is the boot order of devices. This setting is what interests us at the moment.

In order to get into the BIOS, you need to immediately press a certain key on the keyboard when you turn on the computer. Usually, when booting, it is written on the screen what exactly you need to press to get to the BIOS menu. Most often this is the Delete, Esc, or F2 key. You will know that you have entered when you see the BIOS menu in front of you.

The most common options are:

If the attempt is unsuccessful, then reboot the computer and try again. Below are tables with possible options for entering the BIOS.

A table with key combinations for entering the BIOS from various BIOS manufacturers.

BIOS Manufacturer	Keys
ALR Advanced Logic Research, Inc.	F2, Ctrl+Alt+Esc
AMD (Advanced Micro Devices, Inc.) BIOS	F1
AMI (American Megatrends, Inc.) BIOS	Del
Award BIOS	Ctrl+Alt+Esc, Del
DTK (Datatech Enterprises Co.) BIOS	Esc
Phoenix BIOS	Ctrl+Alt+Esc, Ctrl+Alt+S, Ctrl+Alt+Ins

A table with key combinations for entering the BIOS from various computer and laptop manufacturers.

Intel Tangent	Del
Micron	F1, F2, or Del
Packard Bell	F1, F2, Del
Sony VAIO	F2, F3
Tiger	Del
Toshiba	ESC, F1

After you have entered the BIOS, you need to find the option responsible for the boot order of devices. As a rule, these settings need to be looked for in the menu, the name of which contains the word BOOT; of course, there are other options, but as they say - “He who searches will always find.”

To make your search easier, here are a few examples of what it looks like in real life:

Selecting the device to boot first is usually done using the arrow keys on the keyboard, but there are other ways to navigate through the BIOS menu, so if you can’t figure it out, you can look at the help, which is usually visible in the BIOS.

Select your CD/DVD drive as the first boot device and exit the BIOS, saving all changes. To do this, use the Save and Exit Setup item. The computer will reboot and we have thus approached the next stage, for which everything was actually started.

4 Installing Windows 7

If the disk is written correctly and the settings in the BIOS are set correctly, we will see the following inscription Press any key to boot from CD or DVD, which means Press any key to boot from a CD or DVD.

It looks like this:

Press any key

If you don’t see such an inscription, then perhaps you did something written above incorrectly. In this case, check the BIOS again to see if the boot from DVD setting is saved; if everything is set correctly in the BIOS, then most likely your disk is not bootable and you will have to look for another installation disk or download another Windows 7 image.

At this point I will make a small disclaimer. You may come across a Windows 7 installation disk that contains, in addition to Windows itself, additional utilities; in this case, to start the installation, you will need to select the desired item from the menu of your disk. It is also worth noting that in some disks, most of the operations described below will take place automatically, without your participation. There is no need to worry about this; all these settings can be changed if desired after the installation of Windows is completed.

To begin installation, click "Install"

You will be faced with a choice of which version of Windows to install. You need to choose the one for which you have the key. If you have a laptop, then often a sticker with a key and an indication of the Windows version is glued to the bottom. We will need the key itself at the end of the installation. In principle, it can be introduced not immediately, but within 30 days.

We agree to the license terms and click “Next”

Select the full installation.

Select the partition in which Windows 7 will be installed and click "Disk Setup"

An inexperienced person may have questions at this point, so let’s look at it in more detail.

Hard drive setup

Often on your computer's hard drive, in addition to the partitions that you know about (such as C: D: E:, etc.), there may be one or more hidden partitions. This is especially true for laptops that were sold with an operating system already installed. The manufacturer makes such sections in order to be able to restore the system and bring the laptop to its factory settings.

Also often found is a hidden partition of 100MB in size; it is created by Windows 7 itself. This partition is used to implement the BitLocker function; this function is designed to encrypt the system partition. So, in this section there is a program that, when loaded, decodes the encrypted system partition. If you wish, you can get rid of this partition by preparing your computer’s hard drive for installing Windows 7 in advance. For this, it is best to use special programs, such as Acronis Disc Director.

Let's go back to the installation.

Click "Disk Setup" and "Format"

The installer will warn you that all data from this partition will be deleted, but we are not afraid of this, because we prepared for this and made a backup copy of all the information we needed in advance, so we boldly agree by clicking the “OK” button.

After formatting is completed, click “Next”

Waiting for the installation to complete

After installation, you will be prompted to enter your username and computer name.

We enter the key, it can be glued to the bottom of the laptop, or in the form of a sticker on the system unit.

Set a security mode

Set the date, time and time zone

If your computer has a network connection and the system has a driver for your network card, Windows will prompt you to select a connection type

This completes the installation of Windows 7, and you can proceed to installing the drivers and programs you need.

Finally, don’t forget to return the BIOS settings that we changed in paragraph 3 our leadership. You need to set your hard drive as the first boot device in the BIOS, otherwise every time you start the computer it will try to boot from the DVD.

Any Windows 7 or XP operating system installed on a computer or laptop eventually begins to work slowly or freeze. You can solve this problem by trying to remove various types of debris. 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 instruction will tell you about a clean installation of Windows 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, the laptop may not have a disk drive. Therefore, installing from removable media may be the only way. Read how to make an installation flash drive with Windows 7 or XP yourself here. Whichever method you choose: from a USB drive or disk, the following instructions can 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 drive (usually local drive C) will have to be deleted. Therefore, if possible, all files, as well as application data, 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. Using File Explorer, move all files and folders to a safe location.

Additionally, now is the time to think about PC drivers. If you do not have the appropriate disk, you can find and download them via the Internet from the manufacturer’s official website. It would be wise not to use unreliable utilities and drivers found on the Internet, as they may contain viruses.

You will need drivers for a video card, sound module, network card (responsible for connecting to the Internet via a LAN cable), Wi-Fi, Bluetooth, etc. First of all, it’s right to worry about 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 will not be able to download everything else. To simplify dealing with drivers, you can download a program to automatically install them. DriverPack Solution, which works offline, is quite suitable:

Please note that the Windows 7 or XP operating system image must be the same version as that installed on your PC or laptop. For example, you have Windows 7 Home Edition or Ultimate. This means installing the same version correctly. Otherwise, your license key indicated on the computer case will not work. You can find out exactly what version of the system you have installed by clicking on the folder “ My computer» right-click and select « Properties" Here you can see what you have installed. Read how they differ on the Internet.

We start the installation correctly

Now, through the PC BIOS you need to boot from a flash drive or disk. The BIOS is the starting point - the program 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 via BIOS from a flash drive. To do this, when you turn on the computer, depending on the manufacturer, press the key or key combination correctly. In most cases, this is the Delete button. What to press on a particular model can be seen below in the picture. The BIOS will open on the laptop or PC - the device selection menu:

After this, the computer will boot through the BIOS from the flash drive or installation disk. Next, following the prompts, we begin to install the operating system on the laptop. We don't need BIOS anymore. Select the system and installation language:

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

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

The reinstallation of Windows 7 will begin.

All that remains is to wait for the computer to complete the operation. If the installation is interrupted because the PC reboots and starts again from the flash drive, then this problem must be solved using the BIOS.

You need to set the initial boot priority in your computer's BIOS to boot from the hard drive again. After this, 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 PC or laptop case. This is what the sticker looks like:

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

We hope that the instructions “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 unfamiliar terms for beginners as BIOS, bootable flash drive, etc. So, as you can see, if you follow the procedure outlined here, reinstalling the system can be done quickly and not difficult.
