To reinstall Windows 7, you need to go through the "course of a young fighter." You will have to deal with installation options, original images, system versions, as well as writing the OS to a disk or flash drive.
Only after that it will be possible to start the process itself, which is best understood by looking at the instructions. After reinstalling, you will need to deal with the settings of the updated operating system.
Training
Before you learn how to reinstall Windows 7 on a computer, you need to understand the installation types in order to prepare your computer for this process.
You can completely reinstall the OS. In this case, all information from the hard drive will be deleted: this means not only personal data, but also programs with drivers and system documents stored on drive C.
There is an option to update the system. In this case, only system files will be replaced. That is, all the information that is stored on the C system drive. That is why many people recommend not writing any personal data to it.
It must be said right away that updating a system rarely gives the desired result. Many try to reinstall Windows 7 completely. To do this, you need to save all the important files. By what principle is this usually done?
It is best to purchase an external drive, which would then become temporary storage. You can transfer all important files to it: usually users save photos and work documents. Everything else can usually be downloaded from the Internet.
"Pirate" versions
Further, trying to learn how to reinstall Windows 7, another question arises: where can I find the installation files? It’s good if you have a disk with a licensed version or your friend has one. But as practice shows, most users use "pirated" versions.
On the one hand, there is nothing dangerous in author assemblies. But it is worthwhile to understand that in such installation files some services and services are removed, and less important drivers are added. In such assemblies there may also be advertising files.
Versions
Before installing a new OS, you will have to decide on the versions. The installation file can be on 32 bit or 64 bit. Previously, most computers ran on 32 bit version. Now it’s quite simple to decide what is needed for proper functioning.
If your system works with RAM more than 4 GB, and you also need to use resource-intensive programs, then you need to download the OS version on 64 bit. It is also important to remember that most new programs do not work on 32 bit.
More difficult is the choice of Windows: Home, Professional or Ultimate? You need to immediately figure out which one to use, because during installation you will have to choose one of three options.
Most often, users choose Professional or Ultimate. The latter option has no restrictions. It has all the services and services. The Professional edition lacks some useful tools. But as practice shows, most of these services and services are not needed by many users.
Disk preparation
If you need to figure out how to reinstall Windows 7 from disk, you will have to write the image to the media yourself. Of course, if you have a licensed version of the system, you can skip this step and start already with the installation.
But many people want to write installation files to disk. To do this, you need to download an ISO image. After that, it will be enough to download the UltraISO program. It will help to write the image of the system to disk or flash drive.
After starting the program, go to the “Tools” tab, and then click on the line “Burn CD image”. If you simply drag and drop the file, then do not write its contents. Next, you will need to select the OS image that you downloaded from the Internet.
Preparing a flash drive
How to reinstall Windows 7 from a flash drive? If the computer does not have a disk drive, or if it’s more convenient for you to use this particular drive, then you will have to figure out its preparation.
For installation, the aforementioned UltraISO program is suitable. Before you begin, you need to install a USB flash drive into your computer (a drive with a capacity of 4 GB or more is suitable). After you need to find the image of the file and open it. Then you need to find the item "Self-loading".
The program will need to select a recording method. It is recommended to use a USB-HDD. In the line “Image file” you need to specify the address to the installation file.
How to reinstall Windows 7 without a disk? Just the option with a flash drive is perfect. But recording an image is not the last step. Need to go to BIOS. For each system you have to choose your own combination. Usually these are F1, F3, F10, F12 or Esc buttons.
After downloading this menu, you need to select the name of the flash drive in the First Boot Device item. After that, during the reboot, the installation of the system will start automatically.
Without media assistance
But reinstalling Windows 7 without a disk and flash drive is a time consuming and complicated process. Of course, it’s better to use some kind of drive for installation. But if it so happens that there is no way to use a disk or flash drive, you will have to use a hard drive.
First you need to make an OS image, as described above. It must be transferred to drive C. After you can restart the computer. During the download process, you need to click F8, Space or Esc. You have to click on the buttons at the same time to figure out how to start the boot menu.
A black screen appears with the words. Here you will need to select the item “Troubleshooting”. You can move along the lines with the up / down arrows on the keyboard, and the Enter button will help you choose the one you need.
A window will open with system recovery options. Here you need to enter the keyboard input mode. Next, you will need to select the name of your computer. If it is password protected, enter the password. After you need to click on the command line.
When it opens, you will need to enter a couple of commands. The first is necessary in order to get, thus, to the disk with the image of the OS. Enter: X: windowssystem32C.
For the command to activate, you need to press Enter. The same button takes the user to the next command.
We use:> setup.exe. This command starts the installation process.
BIOS
Finally, before the installation process itself, you need to figure out how to reinstall Windows 7 through BIOS.
After you open this menu, you will need to make a number of settings. Go to the Boot devices section. To activate it, you must press Enter. After that, using the arrows on the keyboard, go to Boot Sequence. It is important that this item is responsible for the priority of loading the device.
In the First Boot Device line, select the device on which the system image is stored. For example, if you downloaded the operating system to a flash drive, then indicate its name here.
After the settings, the main thing is to remember to save the changes. Key combinations that will help you do this will be indicated at the bottom of the screen.
Installation start
If you saved all the data, prepared a flash drive, disk or HDD (hard disk), you can figure out how to reinstall Windows 7. On a laptop or computer, the reinstallation process is no different. The only thing: if you use a disk, the system will ask you to click on any button, if a USB flash drive, the download will start automatically.

But still, it is recommended to choose a complete installation. It will require additional settings.
Free space allocation
If this is the first OS installation, you will have to deal with hard disk partitions. Firstly, the system can have several hard drives or an additional solid-state drive. In the list all this will be indicated. Secondly, if the computer works with one hard drive, it is recommended to divide it into partitions. So you can properly organize system and personal files.
How many partitions to share the disk, how much they will be volume - your business. It is important to remember that for the system you need at least 50 GB, and it is better to leave 100 GB.
If the railway is already divided into sections, then it will be enough to format each. To do this, select the section, and click "Format" below.
Final Stage: Setup
After working with partitions, you need to click on "Next" and wait for the installation process to complete. It is painted in stages here, so it will be easy to follow it. If you have an average system, then reinstallation will take about 15-20 minutes.
After that, the computer will reboot itself. It is important at this moment to get a disk or flash drive so that the installation does not start again.
When the computer boots up, the user will be prompted for a username and password. It is not necessary to encrypt the system. The next step is to activate the OS version. If you have a license key, you will need to enter it in the appropriate line.
