How to Change the Operating System on a Computer
With prolonged use of the computer, any user sooner or later is puzzled by the fact that the system is cluttered, the residual files do not want to be deleted voluntarily, and the laptop is loaded at the speed of a wounded snail. Also, some viruses, although treatable at first glance, still leave their tiny footprint. Subsequently, it expands exponentially and affects the entire system completely. Therefore, the user begins to ask the urgent question: “How to reinstall the Windows 7 system?”
Of course, to solve these problems, you can use the services of plug-ins or start using a new antivirus, but such a solution will be temporary, and in a few weeks the situation will not only happen again, but also get worse. In addition, sometimes the computer simply leaves no choice, threateningly welcoming “blue screen of death” with farewell instructions.
Reinstalling the operating system in a specialized salon costs a lot, so today we will save a couple of thousand and learn how to reinstall the OS on our own. But before reinstalling Windows 7, there are a few things you need to do.
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 saving to the flash drive or disk those documents that may be needed in the future.
For example, not everyone wants to lose the achieved result in their favorite game. It is enough to find and save one small file, which is located in the user’s AppData folder. If the folder with the same name does not appear, go to “Computer”. “Local disk.” “Users”. “Your name” and there click on “Organize”, then select the folder and search options in the drop-down menu.
And put a marker on “Show hidden folders and files.”
How to save your favorite content and links from the browser
In order to save bookmarks, before reinstalling Windows 7, you must do the following:
- For the Mozilla Firefox browser, you will need to go to the “Local Disk”. “Users”. “Username”. Favorites and save the entire folder.
- To save Google Chrome data, go to the “Local drive”. “Users”. “Username”. “AppData”. “Local”. Google “Chrome” and save the User Data folder.
- For Internet Explorer, just save the Favorites folder located in the Local Disk. “Users”. “Username”.
- When working with Opera, we go the well-known way to the AppData folder and then Opera, you only need to save the bookmarks.adr file.
To save torrent files, go to AppData, there we find the uTorrent folder and completely copy it. After reinstalling the system, the saved folder must be placed in the same place. This also applies to saved games and bookmarks in browsers.
When all the necessary data, photos and other needs have been successfully saved, we begin reinstalling the OS under the drum roll.
How to reinstall Windows 7 correctly
If there is a disk with an operating system, then insert it into the drive, after which the automatic reinstallation of the OS should begin, although in 60% of cases this does not happen. What to do in such a situation to understand how to reinstall Windows 7? “BIOS”. a mystical word, upon hearing which, many begin to get nervous. In fact, there is nothing wrong with the BIOS if you do not touch anything superfluous (and in this case, all parameters are recoverable). In order to get to the destination, you need:
- restart the computer;
- Press the del key 2-3 times before the Windows splash screen appears. If the transition to the BIOS did not occur, simply repeat the procedure again.
So, if everything is done correctly, the following image should appear before your eyes:
Next, find the First Boot Device and set the value to 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).
Press f10 to save the changes. If all conditions have been met, then the system will reinstall.
The next window prompts us to select the language, date and set the time. We set simple parameters, and boldly click “next”, “install” and accept the license agreement.
- Update — upgrade only if the system is being reinstalled for minor reasons. If the decision was made in connection with the “screen of death” or if malicious programs were clearly populated 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.
Here you have to choose which disk will appear as a local one, i.e. the one on which the software will be installed.
Logically, the volume of the system disk should be within 35 GB, but no less. It should be borne in mind that many of us like to save files on the principle of “I’ll throw it on the desktop so that we don’t forget.” All documents, pictures, etc. that are located on the desktop are stored on the system drive, as well as files from the “Downloads” folder. Thus, when calculating the volume of a local disk, you should be more generous.
Click “Next” and go for a snack, we have a minimum of 45 minutes. During installation, the computer will restart several times, which will kindly warn you. He should not interfere with this, if in the process there are no unforeseen situations, after 45-50 minutes, the new Windows 7 will be successfully installed.
The next step. This is the username and computer name. If at some point you need to change these settings, then this is done simply: “Start”. right-click on “Computer”. “Properties.” We find “Computer name, domain name and workgroup settings” and there we click “Change settings.”
You do not need to set a password, so you can skip this item 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 (if 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 point and forget about this issue for about a month. After 30 days, a beautiful picture on your desktop will change to a black screen, and some functions and devices may turn off. If this does not bother you, then you can safely work with the system further or be puzzled by finding a suitable key in the Internet.
When choosing the type of update installation, it is best to use the recommended options. If the system does not automatically update, then sooner or later minor problems may arise in working with the most frequently used programs. The update eliminates minor flaws and optimizes the OS.
How to reinstall Windows 7 without a disk or flash drive
Sometimes it happens that a drive with “Windows” no, 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 USB flash drive.
Reinstalling the system using a flash drive
To get started, download the OS image to the computer. After that, install the Ultra Iso program or you can use Daemon Tools, the algorithm is approximately the same.
Next, we take a USB flash drive or memory card, it’s worth noting right away that the BIOS will not see any of the drives installed through 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 beyond. information on which side the connectors we need are installed.
In order to prepare a flash drive for further work, you need to format it, even if there is nothing on it. Then we perform the following actions:
- In UltraIso, open the Windows 7 image that we have already downloaded (“File.” “Open.” Select the program image).
- Find “Self-upload” in the top menu and select “Burn Hard Disk Image”.
- In the window that opens, indicate the formatted USB flash drive.
- We confirm the verification, and set the recording method to USB-HDD.
- Click “Write.”
- We agree with the fact that all files will be erased from the USB flash drive (although we formatted it, we still set it to “Yes”).
- Voila! If we see “Recording is completed,” then the job is done, and you can begin reinstalling.
- We go into the BIOS in the known way described above, and in the First Boot Device select the recorded USB flash drive.
Reinstall Windows 7 using a DVD burned image
Another way will tell you how to reinstall Windows 7 via CD-ROM without a license disk.
Why DVD? Everything is elementary, a regular CD-ROM will not work for the only simple reason. there is not enough volume, and the OS image “weighs” about 3 GB.
If for these purposes you decide to use a DVD-ROM, on which there is already something, then, as in the situation with a flash drive, you must resort to formatting.
Now open the well-known UltraIso program, go to the “File”. Open and find the downloaded image of Windows.
Next, go to the “Tools” menu and click on “Burn CD Image”, in the window that appears, check the “Check” box, dutifully agree with the fact that everything on the disk will be destroyed and click on “Burn.”
That’s all, after the message “Recording is complete”, our disk is ready. We think everyone has already guessed what to do next. That’s right: go to the BIOS and select the recorded disc as First Boot Device.
How to return from Windows 7 to XP
Sometimes it’s difficult for users to master a new system, so for some it’s easier to reinstall Windows 7 on XP. The installation procedure is not much different from that described previously, with the exception of a few points:
- After proceeding to the installation, the system prompts you to choose which partition (that is, which drive) the OS will be installed on. In order to root out the previously installed Windows 7, you need to select the appropriate section. After that, there will be a choice of 4 formatting options, the only correct one of which. this is “Format Partition on NTFS”. After that, the computer usually reboots and starts installing the system.
- If there was an acute desire to install two OSs on one computer or laptop at once, then, on the contrary, we select the section that is not occupied by system files. This is usually drive D.
Reinstall Windows 8 to 7
Despite the fact that most users positively rated the seventh version of software from Microsoft, the G8 gathered rather conflicting responses. Since the latest 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 will need to go into the BIOS and set the primary priority on the CD-ROM (how to do this was described earlier).
Next, set Boot Mode to Legacy Support mode.
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 hidden ones. After that, no longer thinking about how to reinstall the Windows 7 computer, we do the rest:
- specify the time, date and keyboard layout;
- We agree to the terms and conditions, indicate the username 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 process of replacing the OS, many users have a number of questions. For instance:
- “Why did the quality of the image deteriorate after installing the new system?”
- “Why does not the computer or laptop see the flash drive?”
- “Why did the sound get worse?” etc.
All this happens most often when reinstallation was carried out by downloading the OS or buying a disk from your hands (you don’t have to think about how to reinstall the Windows 7 computer, but some “jambs” still pop up). In order to solve a number of such problems, just download the drivers from the official website of the manufacturer. Or pay attention to the drivers before reinstalling the system.
Let’s take an example. Suppose, 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 this. How to be
It’s simple, just type in the search engine model (enough and the manufacturer’s company) of the device and add the coveted phrase “Download drivers from the official site.” Then go to the manufacturer’s website link and there, in the appropriate form, indicate the full model of the laptop. Next, you will have to download all the drivers presented in turn and install them on a laptop one by one. There are no tricks to install, since the drivers themselves install themselves where they should.
If, for one reason or another, the drivers go wild and are installed in the wrong place, you can go to the device manager and force them to be updated.
In order to get into the remote control, you can simply type “Device Manager” in the search bar that pops up when you click “Start”. Next, right-click on the driver that is marked with an exclamation mark. And we select “Update drivers”, in a new window it remains only to indicate that the required files must be searched on the computer itself and indicate the place where they were installed.
If all drivers are installed normally in the device manager, the image will improve and the screen resolution will increase to the required level.
A computer can “fly” at any time, so you should consider organizing a 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 cope with this task. The main thing. approach the issue responsibly and spend an hour to save all the useful information from the computer before reinstalling the OS.
