Reinstall the win 7 system. How to reinstall the system on your computer: step-by-step instructions


Talking about the feather Windows installation, we will briefly describe the main stages of installing Windows 7 and focus on the most difficult aspects. Although reinstalling a modern OS is no more difficult than installing a software package, certain points still require clarification.

Booting from external media

To begin, insert the installation disc into the drive and restart your computer. If it started booting from the installation disk, that's good; if not, then you need to change the BIOS settings so that the machine first tries to boot from the optical media.

At the moment when the machine starts to boot, press the Del or F2 button on your computer keyboard. It depends on the brand motherboard, computer configurations, BIOS version and other factors. But, as a rule, pressing one of these two buttons opens the BIOS settings screen.

Your BIOS settings screen will most likely differ from the one shown in the figure, as it depends on the hardware of your specific computer.

  1. Use the left and right arrow keys on your keyboard to select Boo t.
  2. Then use the up and down arrow keys to select Boot device priority and press the key Enter. The section will open Boot device priority.
  3. In it, select the item 1st boot device and press the key Enter.
  4. A window will open Options. In it, select the drive into which you inserted the OS installation disk and press the key Enter.
  5. To exit to the main settings menu BIOS press the key Esc.
  6. Select an item Exit and press the key Enter.
  7. In the window that appears Save configuration changes and exit now? confirm saving the settings by selecting Ok.

The computer will restart and boot from the installation disc. If this does not happen now, then something is wrong with your installation disk. It should be replaced.

Selecting a disk partition

After you run Windows Setup, you will be prompted to select your system language and review the license agreement. Then you need to select the installation type. Choose Full installation to be able to configure Extra options. One of the first steps is to select a section hard drive, on which the installation will be performed.

You can select the same partition on which the previous OS was installed. It is important to remember that for normal Windows operation 7 requires at least 20 GB free space, and for comfortable work It is advisable to have 40 GB. Windows 8 requires at least the same 20 GB disk space, but in reality, even 60 GB may not be enough for comfortable work. These facts should be kept in mind when choosing the partition on which you will install the OS.

Formatting a partition

In our case, the program does not allow you to install the OS on the same partition in which the current system is installed. And this is correct, because there is not enough free space here. Therefore, this section needs to be formatted. This will guarantee that there are no files left from the previous OS on the system disk and it will not affect the newly installed system in any way.

  1. Before you format the highlighted partition, make sure you select the partition you want. Then click on the link Disk setup.
  2. will appear additional settings, among which there will be an item Format. Click on it.
  3. A window will appear warning you about the possible loss of important data stored on the partition being formatted. Confirm your actions by pressing the button OK.
  4. After formatting is complete, select the formatted partition as the drive on which the OS will be installed and click the button Further.

The installation process will begin, which will not require your intervention until a certain stage.

Selecting a username

After completing the OS file setup operations, you will be prompted to enter your username and computer name. This is generally a simple procedure, but you need to take one nuance into account. There are known cases where some applications did not work correctly with Cyrillic usernames. More precisely, not even with names, but with paths to folders, to which the system itself assigns a name identical to the user name. Therefore, to avoid problems in the future, enter the username and computer name here in Latin letters.

This is all the more important because now you are actually creating an administrator account, which will subsequently affect the work of all other accounts (of course, provided that you are not using the computer alone and create Accounts for other users).

Setting a strong password and other settings

In the next step, the installer will ask you to set a password for the user to log in to the system. If you are not the only computer user, be sure to indicate complex password, consisting not only of letters, but also of numbers and at least one special character. This will protect you from outside interference in the system.

For other users in the future, after installation is complete, create separate accounts with limited rights. This will allow you to properly restrict access to your computer and save you from the need to correct errors in the system that arose due to the fault of other users. Later in the installation process you will be required to select options automatic update. Select an item Use recommended settings. This will provide the most reliable protection for your computer. Then you should correctly specify your time zone and current date and time. Depends on correct work many programs, including antivirus.

Some time after the system has made the necessary settings, you will see a familiar and familiar Worker Windows table . This completes the reinstallation of Windows 7.

Any complete reinstallation Windows 7 on a laptop, netbook or computer should start by saving important information to another separate media. For example, on a flash drive or external hard drive. Surely you have important information that you need to save to avoid its loss.

Here you need to proceed from what OS is installed on the computer now. For example, if you want to reinstall XP on Windows 7, then you may need to look for your information in other places than in Windows 7. In any case, double check all possible logical drives, all folders. The most common places where most users store information are:

Secondly, installing Windows 7 on an unformatted logical drive will only add to problems in the future. After all, all the programs that will still have to be reinstalled will remain on it, as well as the folder with old Windows.

Selecting Windows 7 version

Before we begin to describe the installation of the new OS, a few words about the distribution of your Windows 7. This OS, like the previous Vista and subsequent generations, has two branches: 32-bit and 64-bit. The 32-bit version of the system does not allow the use of more than four gigabytes of RAM. This is due to the peculiarity of the architecture. How to reinstall licensed Windows 7? There are several versions of the operating system:

  • Windows 7 Starter. This version of Windows 7 can hardly be called a full-fledged OS. Almost all functions in it are blocked by Microsoft. Windows Starter installed on some laptops. The maximum possible amount of RAM that this 32-bit version of Windows can use is 2 gigabytes.

The fact is that such assemblies may contain errors disabled Windows services 7, and just surprises in the form malware. Now, seven is not so expensive, and you can buy Windows 7 by becoming a license holder.

Reinstalling Windows 7 from a USB flash drive

To reinstall Windows 7 from a flash drive, you need to have on hand one of the versions presented in the table above (the main thing is not Starter). DVD drives are not widely used today. Instead, they were replaced by flash drives. Reinstalling Windows 7 from a flash drive, without a disk, is more convenient. USB flash drive You can always take it with you without worrying whether your computer has a DVD drive or not. In addition, not all laptops are equipped with drives.

To make a bootable USB flash drive with Windows 7, just burn an ISO image of your new system special program. We described the process of creating a flash drive with Win 7 in detail in the article ““. Program for Windows reinstallation 7 mentioned in the article should help. We hope there will be no difficulties.

After you burn the image to a flash drive and save important data, you can begin reinstalling Windows 7. Reinstalling Windows 7 via BIOS is not as complicated a procedure as it might seem at first glance. To do this, you need to reboot and then . Next, exit the BIOS, saving the settings. The computer will select the drive and begin installing Windows 7.

How to reinstall Windows 7

    Hello. So I still don’t understand: is it worth reinstalling Win 7 Starter with formatting the disk, or is it better not to, due to possible undesirable consequences from this? Recently, problems with the operation of the OS have become more frequent, especially when loading it: programs slow down and freeze; It happens that sometimes even the task manager cannot be launched using “hot keys”. I regularly defragment the disk and registry; checking for errors; antivirus, etc. by using standard tools And third party utilities. I constantly monitor HDD status and RAM (there is enough RAM, the paging file size is set correctly), so I came to the conclusion that I probably need to reinstall the OS.

I can’t set up the system - 4 disks, 2 DVDs - Roma, with 8 TB it can hardly see up to two terabytes, but this is enough, should I change 32bit to 64bit or not?

The appearance of errors in the operation of the computer, the absence of a lasting effect after manual cleaning, the desire to update the software and a number of other reasons force the PC owner to look for an answer to the question of how to reinstall Windows. The procedure is not as complicated as it might seem at first glance, and is accessible to users with different levels of computer literacy.

What is Windows reinstallation

The key lack of reinstallation from a traditional update is the following:

Why is it needed?

Long-term use of a computer leads to the appearance of system errors, making it difficult normal work. Among the most common reasons requiring reinstallation of Windows are the following:

  • introduction of a virus that affects the stability of the entire system;
  • the need to install a new advanced version of the OS;
  • critical reduction in computer speed;
  • installation unofficial build with many errors.

Briefly, the procedure for reinstalling the operating system includes a set of preparatory work, choosing an installation location, loading system files and executing primary settings devices. After which you can start working on the unit under the OS that was selected for installation. Below is a step-by-step guide to action, and the video demonstrates the entire process in detail on Windows example 10.

Preparation

Before starting the entire procedure, you should make sure you have a valid activation key. Even if you plan to simply reinstall a previously used version of the OS, the system may require an activation key. It is equally important to make sure that your computer settings meet the requirements of the version of Windows you are installing. You can do this on the official website Microsoft or on the installation disk with the purchased program.

Saving important data

During the reinstallation process, the logical drive on which the installation is installed is formatted. previous version operating system. The rest of the hard drive will remain unchanged. Therefore, before starting work, you must transfer everything important files and documents to any removable media or cloud storage.

On OS versions from "seven" and higher, it is possible to special remedy data transfer, which allows you to save and transfer the following files and information to the updated unit:

  • Accounts;
  • documentation;
  • music and image files;
  • email messages;
  • selected Internet links;
  • video recordings;
  • other files.

For paid programs You must also carefully read those paragraphs license agreement, which relate to maintaining preferences even after reinstalling the OS. Otherwise, the license may be invalidated and use of the software will become impossible.

Selecting the desired media and saving changes is carried out in accordance with the prompts at the bottom of the screen, where the working keyboard keys with their functionality are located.

Start of reinstallation

The first stage of reinstallation begins with restarting the computer after completing the preparatory stage. This will allow the new BIOS settings to take effect.

Launching OS media

When sending the PC to reboot, insert the media with the operating system into the drive or corresponding connector. If the changes were made correctly, the BIOS will boot from removable media, and the Setup Wizard dialog box will open on the screen.

If the hard drive is logically divided into several disks - C, D, E, etc., then the wizard will prompt you to select one of them as a location for placing the OS. You must select a directory with a capacity of at least 35 GB, since here, in addition to the operating system, documents and files saved on the Desktop and placed in the “Downloads” folder will be stored.

Formatting a disk for the system

For complete removal pre-existing system files, the wizard will prompt you to select a formatting option for the disk where the operating system will be located. So, for Windows XP the only the right option There will be formatting in the NFTS system.

Continue installation

Direct installation process necessary files takes at least an hour. In this case, the computer will reboot several times. Therefore, you can safely go about your business without interfering with the operation of the unit and waiting system notification about the successful outcome of the operation.

Create an account

  1. At this step, the computer and the user are assigned a name, which can always be changed by right-clicking on the My Computer shortcut and selecting Properties from the context menu.
  2. Setting a password is an optional item, so you can safely skip it and proceed to the next setup step from the wizard.
  3. Entering the activation key, which is located on the bottom of the laptop, on a special sticker on system unit, on the box with the installation disk. If there is no key (when installing an illegal version of the OS), then you will be able to use the system’s capabilities for exactly a month, after which you will either need to enter the key or look for another version.

Returning BIOS settings

For correct operation On the computer, you need to visit the Boost section of the BIOS software environment again and set the hard drive as the priority OS boot location.

Additional Information

Modern versions of the OS independently load working drivers for the video card, speakers, etc. If these components begin to work incorrectly, you can always load them yourself using one of the utilities like Driver Booster. It will help in this case and forced update drivers via Device Manager:

  • open Device Manager - in the My Computer context menu, select the Management option and activate the corresponding section in the window that opens;
  • right-click on the device with a yellow exclamation mark;
  • select the “Update drivers” option, indicating the search path for executable files - on the Internet or in specific folder on PC.

How does the installation process of Windows 10 and 8 differ from older versions?

There are several installation options available for the Windows 10 operating system:

  1. Update via Update Center. Can be used if the computer previously worked under “seven” or “eight”. For everyone else more earlier versions There is only one way possible - installing the distribution from a boot disk or flash drive.
  2. Installation over a previously installed OS by updating from bootable removable media. Not applicable for Windows Vista, you will need to install version 7, then 8.1 and only then 10.
  3. Installation from scratch. As fast as possible, but will require re-downloading installation files for all third-party games, applications, programs, etc.

For Windows 7, 8 and Vista, the installation procedure is identical, so once you install the same Vista yourself, you can confidently perform the work of loading system files for version 7 or 8.

Thus, the process of reinstalling Windows is almost completely automated, which allows even a novice PC user to cope with the procedure. Having sequentially gone through the steps of the installation wizard, you can start working immediately after rebooting the computer.

In today's article we will look at the issue of reinstalling the operating system (hereinafter referred to as OS) Windows 7.

Most users greatly exaggerate the complexity of reinstalling Windows 7; in reality, this process is quite simple, the main thing is not to rush and carefully follow the recommendations outlined in the article.

So let's get started.

Step 1: Back up your data

Before you reinstall Windows 7, you need to copy all important data from the system disk.

As a rule, this is the content of standard folders Videos, Documents, Downloads, Images, Music, Desktop, etc.

In the BIOS menu we need to select boot from DVD drive, save the changes, after which the computer will reboot.

After all the manipulations in the BIOS, it will boot not from the computer’s hard drive, but from the installation drive.

If everything is done correctly, then after the reboot you should see the following image on the monitor screen:

Step 3: Reinstall Windows 7

On at this stage The contents of the installation media are loaded into the computer's RAM.

The following 2 screenshots show the initialization of the Windows 7 installer:

Starting from this window we have the opportunity to customize our OS.

At this stage, we can select the language (the “Installed language” field), the display of the time format (the “Time and currency format” field), the keyboard layout or the input method on the tab of the same name.

As a rule, there is no need to change anything here and you can safely click “Next”.

And if this step was not completed initially, you should restart the computer, go into the BIOS, select boot from the hard drive, perform a backup, and then go through all the previous steps again.

If all data is saved, select the system disk and click “Format”.

Important: Do not confuse the system drive on which the OS is installed and the logical drive(s) on which you store data. In our case, “Partition 2” is the system disk, “Partition 3” is the logical disk on which the data is stored.

The system once again warns that all data on the disk being formatted will be deleted. Click "OK".

After this, the direct installation of the OS on the hard drive begins, which is divided into several stages.

At all stages, installation occurs automatically, without user intervention.

Installation time, on average, takes 10-15 minutes and depends on the characteristics of your computer.

After rebooting, you need to go to the BIOS menu and select boot from the hard drive, saving the settings.

If you did not have time to complete the BIOS setup procedure at this stage, you can do it later.

Installation media can be removed, the operating system is installed on the hard drive, but is not configured.

The next step is to enter your username and PC name. Usernames and PC names can be absolutely anything, can contain capital or lowercase Latin and cyrillic letters, numbers.

To switch the language, use the layout switching panel (located at the top). Click “Next”.

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 Norton Ghost or a built-in backup system. In this article we will try to describe in as much detail as possible how to install Windows 7.

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

Setting up BIOS to reinstall Windows 7

We have already considered this issue when installing Windows XP from a disk and a flash drive. 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 your laptop or motherboard manual.

At the bottom of the main window, you can use the mouse to configure the required boot order ( Motherboard BIOS P8H67-V board), moving the corresponding icons to the left or right. Selecting an icon optical drive and move it to the left, in front of the HDD or SSD.

You can also configure the loading order in advanced mode on the tab Boot. In line Boot Option #1 you need to select a DVD drive

Next, set the HDD or SSD operating mode 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. In line SATA Mode change the parameter IDE Mode on ACHI Mode .

The settings will be saved and the computer will restart.

Reinstalling Windows 7

Insert the burned disk with the image and restart the computer. 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 have the opportunity to configure an HDD or SSD (convenient for new drives). Function Create— allows you to create a partition on a drive of the selected size. 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 necessary programs, allocate enough space for system recovery (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 NOT system partition there is a format function, the use of which seems more rational than formatting in installed system. We partition the disk according to your requirements and click Further. How to partition a hard drive on an already installed operating system Windows system 7 can be read.

The latest one is loaded by default installed Windows 7.

To prevent the Boot Manager from appearing and the selected operating system to load immediately, you can do the following.

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