Preparing and saving data

How to reinstall Windows 7? In order to protect yourself from losing important files after reinstalling the system, it is worth spending a little time and save those documents that you may need in the future on a USB flash drive or disk.

For example, not everyone wants to lose the achieved results in their favorite game. It is enough to find and save one small file, which is located in the AppData folder of the user. If the folder with this name is not displayed, go to “Computer” - “Local disk” - “Users” - “your name” and click “Arrange”, then select the folder and search parameters in the drop-down menu.

When all the necessary data, photographs and other usefulness have been successfully saved, we begin to reinstall the OS for the drumming.

How to reinstall Windows 7

If there is a disk with the operating system, then insert it into the drive, after which the automatic reinstallation of the OS should begin, although this does not happen in 60% of cases. What to do in this situation, to understand how to reinstall Windows 7? "BIOS" - a mystical word, having heard that, many start to get nervous. In fact, there is nothing wrong with the BIOS if you don’t touch anything extra (and in this case, all parameters can be restored). In order to get to your destination, you need:

  • restart the computer;
  • 2-3 times press the del key before the Windows screen saver appears.If the transition to the BIOS did not happen, just repeat the procedure again.

So, if everything is done correctly, the following image should appear before your eyes:how to properly reinstall windows 7

Next, find the First Boot Device and set the value on the CD-ROM. This means that when you start the computer, it will first automatically download data from the disk. After installing the software, it is very important not to forget to return everything as it was, or the computer will always install the system (if you also forgot to remove the disk).how to reinstall windows 7 bios

Press f10 to save the changes. If all the conditions have been met, the system will be reinstalled.

The next window prompts us to choose a language, date, and set the time. We set simple parameters, and boldly click “next”, “install” and accept the license agreement.

  • Upgrade (upgrade) - suitable only if the system is reinstalled for minor reasons. If the decision was made in connection with the “screen of death” or malicious programs are clearly on the computer, we definitely choose the full installation.
  • Full installation (custom) - reinstalls the OS literally from scratch, mercilessly destroying everything that could harm it.

Disk configuration

Here you have to choose which disk will appear as a local one, i.e., the one on which the software will be to reinstall windows 7 system

Logically, the system disk should be within 35 GB, but not less. It should be borne in mind that many of us like to save files on the principle of “kin while on the desktop, so as not to forget.” All documents, pictures, etc. that are located on the desktop are stored on the system disk, as well as files from the Downloads folder. Thus, when calculating the volume of a local disk, it is worth being generous.

We press "Next" and go to eat, at least 45 minutes we have. During installation, the computer will restart several times, which will kindly warn you. It’s not worth hindering this, if there are no unforeseen situations in the process, in 45-50 minutes the new Windows 7 will be safely installed.

The next step is the username and computer name. If at some point you need to change these settings, then this is done simply: “Start” - by right-clicking on “Computer” - “Properties”. We find “Computer name, domain name and workgroup parameters” and click “Change settings” there.

It is not necessary to set a password, so this item can be skipped by clicking "Next".

You will also need to enter a product key. You can find it on the bottom of the laptop or on a special sticker on the system unit (in the event that you purchased the equipment with a licensed disc).

If the software was installed from another disk, then the key must be indicated on the box. Well, if the system was installed illegally, you can skip this item and forget about this issue for about a month. After 30 days, the beautiful picture on the desktop will change to a black screen, and some functions and devices may turn off. If it does not bother you, then you can safely work with the system further or be puzzled by the search for a suitable key in the Internet.

When choosing the type of installation of updates, it is best to use the recommended settings. If the system is not automatically updated, then sooner or later there may be minor problems with the most frequently used programs. The update fixes minor bugs and optimizes the OS.

How to reinstall Windows 7 without a disk or flash drive

Sometimes it happens that there is no “Windu” disc, or the CD-ROM is blind and categorically refuses to cooperate. Do not despair, there are no hopeless situations. There are several ways to install the system using other media. For example, you can reinstall Windows 7 from a flash drive.

Reinstall the system using a flash drive

First, download the OS image to your computer. After that, install the Ultra Iso program or you can use Daemon Tools, the algorithm is approximately the same.reinstall windows 7 from a flash drive

Next, take a USB flash drive or memory card, just notice that the BIOS will not see any of the drives installed via the USB-3 connector, so be careful and use USB-2. Externally, the connectors do not differ, in some devices, USB-3 is marked in blue. If there is no identification mark, then everything is simple. We find in any search engine information about the characteristics of a laptop or computer, and further - information on which side the necessary connectors are installed.

In order to prepare the flash drive for further work, it must be formatted, even if there is nothing on it. Then we perform the following actions:

  • In UltraIso open the image of Windows 7, which we have already downloaded (“File” - “Open” - select the image of the program).
  • Find “Self-upload” in the top menu and select “Burn hard disk image”.
  • In the window that opens, specify the formatted flash drive.
  • We confirm the check, and the write method is set to USB-HDD +.
  • Click "Write".
  • We agree with the fact that all files will be erased from a flash drive (even though we formatted it, we still put "Yes").
  • Voila! If we see "Recording is complete", then the matter is done, and you can begin the reinstallation.
  • We go to the BIOS in the known way described above, and in the First Boot Device we select the recorded USB flash drive.

Reinstalling Windows 7 using an image recorded on a DVD

Another way will tell you how to reinstall Windows 7 via CD-ROM without a licensed disc.

Why DVD? Everything is elementary, a regular CD-ROM will not work for the only simple reason - the volume is not enough, and the OS image weighs about 3 GB.

If you decide to use a DVD for this purpose, which already has something, then, as in the situation with a flash drive, you need to resort to formatting.

Now open the already well-known UltraIso program, go to “File” - “Open” and find the downloaded image “Windows”.

Next we go to the “Tools” menu and click “Burn CD image”, in the window that appears, check the box “Check”, humbly agree with the fact that everything on the disk will be destroyed and click “Burn”.

That's all, after the message “Record Completed” appears, our disk is ready. We think everyone has already guessed what to do next. Correct: go to the BIOS and select the recorded disk as First Boot Device.

How to get back from Windows 7 to XP

Sometimes users find it difficult to master a new system, so some find it easier to reinstall Windows 7 on XP. The installation procedure is not much different from that described earlier, with the exception of a few points:

  1. After the transition to the installation, the system offers to choose which partition (that is, on which disk) the OS will be installed. In order to root out the previously installed Windows 7, you need to select the appropriate partition. After that, there will be a choice of 4 formatting options, the only correct one of which is “Format partition in the NTFS system”. After that, the computer usually restarts and starts the installation of the system.
  2. If there is a keen desire to install two operating systems at once on one computer or laptop, then, on the contrary, select the partition that is not occupied by system files. This is usually drive D.

Reinstalling Windows 8 on 7

Despite the fact that the majority of users positively evaluated the seventh version of the software from Microsoft, the G8 collected rather contradictory responses. Since the newest version is fundamentally different from all previous ones, sometimes there is a desire to replace the OS.

In order to reinstall Windows 8 to 7, you need to go into the BIOS and set the primary priority on the CD-ROM (how to do this was described earlier).

Next, set the Boot Mode to Legacy Support mode.reinstall windows 8 by 7

After that, save the changes and proceed to boot from disk or from other media. The type of installation when changing Windows 8 to 7 can only be “New Installation”, since the OS is different, there is no need to talk about any updates.

It is also necessary to delete all sections, including the hidden ones. After that, no longer thinking about how to reinstall a Windows 7 computer, we do the rest:

  • specify the time, date and keyboard layout;
  • agree to the terms, specify the name of the user and computer;
  • enter the key, etc.

After installation (drivers)

As a rule, reinstalling Windows 7 on a laptop or computer is quite easy, but after the OS replacement process, many users have a number of questions. For example:

  • “Why did the image quality deteriorate after installing the new system?”
  • “Why doesn’t a computer or laptop see a flash drive?”
  • "Why did the sound deteriorate?", Etc.

All this happens most often when the reinstallation was done by downloading the OS or buying a disk from hands (you don’t have to think about how to reinstall the Windows 7 computer, but some of the “jambs” still pop up). In order to solve a number of such problems, it is enough to download drivers from the official website of the manufacturer. Or pay attention to the drivers before reinstalling the system.

Let us consider an example. For example, before reinstalling Asus Windows 7, the user was not puzzled by the question of saving data from his laptop, or he simply did not have the opportunity to do it. How to be?

It's simple, just type in the search engine model (enough for the manufacturer) device and add the cherished phrase "Download drivers from the official site." After that, go to the link of the manufacturer’s website and indicate the full model of the laptop in the appropriate form. Next you have to download all the presented drivers one by one and install them one by one on a laptop. There is no wisdom in the installation, as the drivers themselves install themselves where they go.

If for one reason or another the drivers went into revelry and were not installed where they should be, you can go to the device manager and force them to update.

In order to get into the remote control, you can simply type "Device Manager" in the search box that pops up when you click "Start". Next, right-click on the driver that is marked with an exclamation point. And select "Update drivers", in the new window it remains only to indicate that the required files should be searched on the computer itself and indicate the place where they were installed.

If all the drivers in the device manager are installed normally, the image will improve, and the screen resolution will increase to the required level.


A computer can “fly” at any time, so you should think about organizing backup storage of high-value files before reinstalling Windows 7. Thus, you can save a lot of time after installing the system, because it is possible that even the most basic programs ( Word, etc.) will have to re-search and install.

Reinstalling Windows 7 on a laptop or computer is not difficult; even a novice user can handle this task.The main thing is to approach the question responsibly and spend an hour to save all the useful information from the computer before reinstalling the OS.
