Installing Windows on a computer without a disk or flash drive. How to reinstall Windows without a disk and flash drive How to reinstall Windows 7 without a disk

How to reinstall Windows 7 without a disk? This topic is relevant today. Moreover, it concerns the new OS developments that appeared not so long ago. And now in more detail! Windows 7, or simply “seven,” is one of the latest operating systems from Microsoft, and at the same time the most successful of them. At least that's what many experts think.

What does installing from a boot drive mean?

How to reinstall Windows 7 without a disk? The standard model for installing any operating system is from a hard drive. And in addition to a disk, a drive can be used as it. The installation option from a flash drive is quite reliable. As with a disk, the host system is installed at a lower level in the computer's software hierarchy. In other words, “from under the old system.” In addition, this method of loading a new “OS” allows you to format the hard drive on which the previous system was located. This will protect the OS from old programs that may be malicious, as well as from “under-deleted” parts of files that are invisible at first glance, but remain in the system and interfere with its normal operation. Such “scraps” of unnecessary documents hinder the speed of the system. Malfunctions may occur. You should consider how to reinstall Windows 7 without a disk and without a flash drive.

If there is neither a flash drive nor a disk

The standard installation method is not always possible. For example, if there is no disk, but there is an OS file on the computer or laptop itself. What to do in such a situation? How to reinstall Windows 7 without a disk or flash drive on a computer? The system file can be presented in the form of an image, an archive, or simply an installer. To install the system from an image, you must run a special program. It is necessary for reading/writing exactly this kind of formats. For example, Daemon Tools. Having launched the image in the program and mounted it, you should select the installation file. If the OS is available as an archive, then there is no need to unpack it. How to reinstall Windows 7 without a disk or flash drive on a computer in such a situation? Click on the archive and select the installer file from the drop-down list. It has ".exe" permission. This file is located mainly towards the end of the list of archive contents. There will be no difference in launching the installer even if the operating system is simply located in some folder.

What do you need to remember?

If you are installing a production system for the first time, there are some rules to keep in mind. You need to know them if you need to answer the question of how to reinstall Windows 7. Whether this will be done without a disk or with it does not play an important role.

Firstly, the installation of a new OS may occur due to the computer being infected with viruses. This is a useless process if it is not accompanied by formatting. The fact is that infected files do not disappear anywhere with this type of installation of the main working environment. They are saved in the previously installed system. Subsequently, they will simply switch to a new shell.

Secondly, the best, and most importantly, the safest installation method is still to use a hard drive. Reinstalling Windows 7 without a disk in such a situation is not difficult. It is enough to have a bootable USB flash drive. If it does not exist, then it is created using simple steps. There is a program specifically for this that writes images to media. For example, Ultra ISO. Accordingly, if the files are not in disk image format, you should create one. Usually the same Daemon Tools is used for this.

How to reinstall Windows 7 without a disk on a laptop or computer? It should be remembered that when installing a new system, you should always use only verified files. The fact is that with modern progress, handicraft assemblies are found everywhere. When downloading Windows 7 from the Internet, no one can say with confidence that it is not “hard-wired” with malicious software.

First actions

How to reinstall Windows 7 without a disk on a laptop or computer? Let's look at how to do this in the simplest way. Find the folder with the operating system and run the installation file. After this, the installation window will open. It will display the ability to configure the following settings:

For our country, naturally, you should choose the Russian language option everywhere.
After clicking the “Next” button, a window with the “Install” button opens. By clicking on installation, we go to the license agreement. We accept it by checking the box next to the appropriate inscription.

The most popular types of systems

The installer may contain several system options. The most commonly used:

If you are wondering how to reinstall Windows 7 without a disk or flash drive on a laptop or computer, then you should understand that this is an incomplete list of possible systems.

Don't forget about the bit depth

All programs of this type differ in their bit depth, that is, 32-bit (X86) and 64-bit (X64). This parameter is indicated after the system name. For example, Windows 7 Ultimate X86.

The choice of the level of the system to be installed should be made based on the power of the computer's resources. If the laptop or PC is relatively weak, it is recommended to install X86 OS (32-bit version). It is best to install Windows 7 X64 if the RAM size exceeds 4GB. The thing is that the 32-bit version is simply unable to “see” such a volume.

What to do when formatting is needed?

Let's get back to how to reinstall Windows 7 without a disk. The next OS installer window will offer the option of completely installing the system on your computer and updating. You must opt for a full installation. Otherwise, only an update to the pre-existing operating system will occur.

After selecting the preliminary parameters, a window appears with the ability to select a hard drive. This method will not allow you to format it. This is due to the fact that the installer was launched from a running system. If it is necessary to format the disk, which is desirable when installing the OS, then this point can be bypassed. This happens as follows. Until the new “seven” is installed, take any other partition of the disk and clear it of files (move them if you need them, and just don’t touch them if you don’t need them). After that, format the partition. You should not change the drive letter in this situation. When answering the question of how to reinstall Windows 7 without a disk or flash drive on a laptop or computer, you should keep in mind that when you boot the new system, the drive letters will change automatically. The formatted partition should be selected for system installation.

If cleaning is not needed

If formatting is not necessary, you can simply select the drive to install the new system and continue. In such a situation, the old system will remain in the “Windows old” folder. It will be located on the “C” drive. It will also be possible to start and work from it. But it is not recommended to do this, since two identical operating systems on the same disk may “conflict”. This, in turn, will lead to a malfunction. The old OS can be removed or moved to another medium. There is another very significant point that you should remember when answering the question of how to reinstall Windows 7 without a disk on a laptop from Asus, Lenovo, HP, etc.

If the partition on which the new OS is installed does not have enough space for two operating systems, the installation process will not be able to start. This occurs due to the fact that the old shell is not removed and continues to occupy space. It is important to remember that frequent reinstallation of the operating system leads to disk destruction. This can be avoided by using different types of defragmenters. For example, the Victoria program.

This problem is not so bad for computers. There is nothing easier than buying a new hard drive and installing it. This is easy to do yourself. However, if the hard drive breaks on a laptop, then, in addition to the cost of the disk itself, you will have to pay for repair services. You should know about this if you are interested in the question of how to reinstall Windows 7 without a disk from a flash drive.

What do you need to enter after installation?

Having selected the disk (partition) for installation, click “Next”, which will lead to unpacking and subsequent installation of the new Windows 7. This process is fully automated. It will last for 25-30 minutes, depending on the power of the computer (laptop). After completing the installation, you need to enter the following parameters:

If the input is incorrect, the system will tell you about it and ask you to correct the symbols, indicating the error.

Entering the password and key

During installation, you will be asked to assign a password and a hint in case you lose it. After this, a window appears in which you must enter the key to activate the operating system. If it is missing, simply click “Next” after unchecking the box next to “Activation while connected to the Internet.” Then you will be able to activate the system in any convenient way. This is done as follows:

You need to protect your computer from external threats

Let's return to the question of how to reinstall Windows 7 without a disk on a computer or laptop. The next step is the protection settings. You can use the recommended service, or you can postpone the decision and configure it later. Protecting your computer is one of the most important aspects of installing an operating system. The fact is that the security of the equipment will depend on how well you limit access parameters from other people’s devices. This menu is nothing more than offering an option to select a data protection set created by Microsoft specialists. It should be understood that they already provide and set the recommended parameters. By skipping this point, many people forget to perform the configuration manually in the future, putting their files at risk.

So, having decided on security, click “Next” and configure the time and date (time zone, etc.) in a new window.

Next, the installer displays the network parameters window. It can be either home or public. Due to this, the settings in the Internet properties are changed. As for the general understanding, the home network looks more conservative regarding the configuration. A public network, on the contrary, provides greater access to the resources of a laptop or computer.

What can be changed after installation?

This was the last step, after which you will get a practically empty desktop of the newly installed Windows 7 operating system. Basic settings (for example, adding the My Computer folder or user files to the desktop) can be done by left-clicking on the desktop space and selecting the "Personalization" tab.

There you can also set a different background image, change the default theme (usually Windows 7 Aero), change the screen resolution, and much more.

Standard licensed Windows 7 comes without additional programs. However, among the numerous assemblies you can find options that include many additional elements, software, and so on.

Conclusion

This article described how to reinstall Windows 7 without a disk or flash drive. You will install it on a netbook, laptop, computer - it does not play a big role. The principle of the installation process for a new system is the same.

Most laptop users are faced with situations where they need to reinstall the operating system, often while keeping the licensed Windows. This publication discusses several methods of how to reinstall Windows 7 on a laptop, and also talks about the nuances of the process of installing the OS on laptops from different manufacturers.

Restoring the system using a Windows 7 backup

Most mobile computer manufacturers create backup storage for 7 distributions or any other OS. Reinstalling Windows 7 on a laptop from these memory areas is done using built-in utilities.

To start the reinstallation, reboot your laptop and press:

for Windows on an HP laptop on F11;
on an ASUS laptop on F9, boot immediately when you start;
for Windows 7 on a Lenovo laptop on F11;
On an Acer laptop, the key combination Alt + F10 is suitable;
for Windows 7 on a SAMSUNG laptop on F4.

After pressing the desired key, instead of the standard Windows 7 boot, the OS recovery interface will open:

After downloading the program, follow the instructions to restore Windows.

But remember that all settings will be reset, and data from the previous copy of the system may be deleted.

Reinstalling from disk

When reinstalling from disk, remember that to restore the license you need to use a distribution kit with exactly the same OS as was installed previously. You can find out the version of the installed system on a sticker, which is usually located on the back of the laptop. By the way, the license key for your copy of Windows is also located there.

Remember that when you reinstall, a new operating system is deployed from the disk, and to avoid problems in the future, you should delete the data from the previous Windows.

This is accomplished by formatting the system partition, so take care in advance to transfer all the necessary data from the selected hard drive volume to install Windows. It is not advisable to transfer installed programs, since this will lose connection with the registry, and many of them may not start. Don't be lazy, install them again after replacing the OS.

The installation disk distribution does not include drivers for all laptops, so download the drivers for your device in advance from the manufacturer’s official resource. If this is not done, then after installation there is a high probability of the following problems occurring:

The network card does not work;
Wi-Fi does not work;
Applications do not launch.

If you reinstalled the OS without this, then to troubleshoot network equipment you will have to download the driver distribution using another computer and transfer them using removable media, so before reinstalling, do not forget to play it safe and download drivers for the network card and Wi-Fi module.

To begin the installation process, insert the disc into the drive and restart your laptop. After your computer starts, open the boot menu and select boot from DVD.

This dialog is called up on most laptops using the F12 key, and on HP devices the combination F9 + Esc is used.

Often on older computers this function is missing, so you will need to open the BIOS and edit the boot priority yourself. To go to the BIOS on laptops, manufacturers use the following keys:

Acer, Asus, Samsung, Lenovo - F2;
hp - F10 + Esc .

If the brand of your device is not in this list, then find out the actual key for it on the window that loads when you turn on the PC.

The BIOS interface from different manufacturers is not similar in appearance, but the sequence of actions for changing the boot priority is almost identical. Navigation through the windows of a running BIOS of all versions is carried out using the arrows on the keyboard and the Enter, Esc, +, - keys.

Sequence of actions for BIOS AMI:

Sequence of action for BIOS Phoenix-Award:

Windows installation

After making a change to the BIOS and rebooting, a dialog will appear with the message: “Press any key to boot from CD or DVD.”

Further installation of Windows 7 is not difficult, do the following:

Press any keyboard key.
Wait until the file unpacker completes; a screen with the entry “Windows is loading files...” is displayed.
In the dialogue " Windows installation» Specify the language and click on the Next button.
In the window that appears, click on the large Install button.
Select the version of the system to install that has a license code. You will need to enter it after reinstalling Windows 7.
Agree to the licensing terms.
Select installation method - " Full installation».
Select the drive volume on which you are going to install the OS and prepare it by clicking on the item " Disk setup».
There are situations when a reserved drive partition is present in the list; be sure to select another volume.
If you have disks with a capacity of more than 250 GB, it is worth splitting them into several. Typically, a separate partition of up to 100 GB in size is allocated for system installation.
Format the selected drive partition. A warning will appear that all information on it will be deleted. Confirm your consent, because you have previously saved all the necessary data. Wait for the installation to complete and click on Next.
Wait for the installation process to complete; on average, it lasts from fifteen to twenty-five minutes, the duration depends on the configuration of the laptop.
Fill in the fields provided with your username and PC name.
Protect your account with a password, or you can skip this step.
Enter the key copied from the sticker on your laptop.
Select your security options.
Set the date and time.
If you have a network connection, specify the connection type.

Reinstalled Windows is ready to go. If you changed the boot priorities in the BIOS, return the hard drive to first place in the list, otherwise the computer will constantly try to start from the DVD.

Reinstallation from a flash drive

Many compact PCs, such as netbooks, do not have a DVD drive. Therefore, the question arises of how to properly reinstall Windows 7 on them. The answer is simple - use removable media.

To reinstall from a flash drive, you need to download the Windows 7 distribution image in ISO format and write it to this media using a special utility. Remember, in order to properly reinstall a licensed Windows system, you need to download a container with the same OS version. The flash drive itself must have a capacity of at least four gigabytes.

Burning Windows to media using the most popular utility among analogues Ultra ISO is performed according to the following algorithm:

The installation flash drive is ready, but to start the installation, you need to select " USB-HDD" How to set up the BIOS is described above, all steps are similar, you just need to select another entry from the available list. Further installation is no different from installing Windows 7 from DVD.

Often after reinstalling Windows does not work. To solve this problem, take another OS distribution and repeat the installation process. In addition, many users ignore the need to format the partition and reinstall the seven on a disk that already has an installed copy of the system. Avoid this as it can also cause problems.

Conclusion

This article covered reinstalling Windows 7 in several ways. If there is no backup copy, then this procedure should be carried out from a disk on which exactly the same version of the OS is recorded. Some laptops do not have a CD-ROM, so reinstallation can only be done using external media, for example, a flash drive.

The Windows 7 operating system has been and remains the leader among installed operating systems around the world, despite the growing popularity of the new “Ten”. The coverage of everyone's favorite operating system is more than 55% of all computers on the planet. And users often wonder how to learn how to install Seven on their own.

The OS itself is nothing more than just a program, a complex one, but it is a program that can be susceptible to various types of hacks and hacker attacks. Computer hardware also does not last forever, and when upgrading or replacing faulty equipment, reinstalling the operating system is often required.

In the period from the summer of 2015 - during the year there was an update to “ten”, and at the end of the period this update was already forced. Users could not refuse it. And many forced owners of a new product want to return their beloved, stable Windows 7, but, unfortunately, they do not know how to do this.

Features of reinstalling Windows

This article is devoted to reinstalling Windows 7 on computers and laptops, for everyone who does not know how to do this, or is afraid to reinstall Windows 7 on their own for the first time.

In the article you will find:

Detailed description of the installation itself - step-by-step instructions;
Images of the installation progress and subsequent settings;
Tips and tricks during installation.

Preparing to reinstall Windows

Let's get started:

First of all, you need to take care of the safety of important data: copy all photos, videos and documents to reliable storage, this can be removable media or the cloud. And if your OS does not boot, you can try booting from a Live CD to copy the data. Or connect an external hard drive and remove the necessary files from your drive.

Reinstalling Windows, in this case we will talk about “Seven”, is very simple.

You will need a Windows 7 image. You can download it online or purchase the boxed version. For those who don’t know, this is the version of the OS on a disk or flash drive that you can buy in a store.

If with boxed versions everything is clear: you pay money and get a ready-made image, then in the case of purchasing online, this downloaded image must first be prepared, that is, written to a USB flash drive or disk.
The most common program for burning images is UltraISO. The utility is free and easy to use, and the Internet is full of information on how to prepare bootable media for installation on computers.

Set boot priority in BIOS

Conventionally, we have prepared the image, now you need to install it on your computer.

In more modern motherboards, the interface is usually graphical, but it is not difficult to understand. Just look for partitions (boot priority).

Loading a USB flash drive or disk with an image via the Boot menu

This manipulation is needed only once, and after installing Windows, everything will need to be returned to its place. Instead, you can simply reboot, at the moment when information about the installed memory appears on the screen, press the key to enter the Boot menu. Usually these are keys "F11", "F12" or "Esc", but not always. Again, there is a hint on the initial loading screen. In the window "Boot menu" select your storage medium (disc or flash drive) and click "Enter".

Start installing Windows 7

It is advisable to read more detailed information about the installation progress and hardware requirements - click on the link with a description of more detailed information at the bottom of the window. The system recovery button is needed for specific cases when it is necessary to restore damaged files. We don’t need to go there now, so we just click "Install".

Which OS bit size to choose: 64 or 86

Advice: if you have up to 3 GB of RAM installed on your computer, then you should choose the 32-bit (x86) version; if from 3 and above, then 64. This choice determines how stable and fast Windows will work. With 1 GB of RAM - Maximum 64-bit, the operating system will of course be installed, but working on it will be simply painful. It will slow down and hang terribly.

In the next window you should read the license agreement, it’s not easy to scroll through and agree, but read, you never know what kind of data you will entrust to Microsoft under this license agreement? What if you don’t like it and in this case it would be better for you to refuse to use this product. Check the box "I accept the terms of the license agreement" and click "Further".

We are interested in the complete installation, so we select the second tile (Full installation of new version).

Formatting a hard drive when reinstalling Windows 7

When reinstalling Windows 7, you need to format the “Local Disk” on which you installed Windows. Otherwise, the OS will be installed on top of the old system, and the files of the old OS will be placed in the Window old folder and will only take up space on the hard drive.

For example: you have a 100 GB disk, and you need to create a 50 GB installation partition. Write in the window the required size of the future system disk and click "Apply". For the remaining space, create a second or more Local Disks. When creating a new partition, the system will warn you about the creation of additional reserved partitions.

Clean installation of Windows on your computer

Completing the installation - activating and setting parameters

Beware of fakes and the use of pirated assemblies. Believe me, this will not bring anything good.

To install Windows 7 on computers that do not support a disk drive (for example, netbooks), you can use a flash drive, the volume of which must exceed 4 GB to completely accommodate all the distribution files necessary for correct installation and subsequent operation of the system.

Before installing Windows 7, you will need to download an operating system image. This can be done both on the official Microsoft mirror and on third-party resources. After downloading the image, you will need to install a program that will allow you to format the flash drive into the desired format and record all the files in the image. Among the most convenient programs for recording Windows 7 is the Windows 7 USB/DVD Download Tool. The program is available on the official Microsoft website and allows you to write a licensed image to removable media.

Flash drive recording

Insert the USB flash drive into the device and run Windows 7 USB/DVD Download Tool. A simple program interface will appear in front of you, through which the already downloaded image is recorded. Click on the “Browse” button and specify the path to the ISO system image file that you downloaded earlier. Once selected, click "Open".

After specifying the path to the image, click on the Next button to proceed to writing the image to removable media. In the next menu, select USB Device. In the list provided, select the name of your flash drive, and then click Begin copying. Next, click Erase USB Device, and then confirm the information. After this, recording the image to the USB flash drive will begin, the process of which you can monitor in the main program window. Once the record status line is 100% full, you will see the Backup Completed message. The image recording is complete and you can begin installing the system.

Actions after recording

Before reinstalling the system, save all important files on separate media, as documents may be deleted during the installation process. After this, go to the computer's BIOS by pressing the Start Setup key (F2 or F4) when the computer boots. Go to the Boot section and select the name of your flash drive as First Boot Device. Save your changes and restart your computer. If the image was recorded correctly and the BIOS settings were specified correctly, installation and initial configuration of the operating system will begin.

Attention!

For faster, more stable and convenient downloading, I recommend using a downloader, for example, Download Master. not a browser, especially Google Chrome (often does not download files).

Original Windows 7 Ultimate:

Original Windows 7 Ultimate image with USB 3.0 drivers:

Not long ago I was faced with the fact that I needed to download the original version of Windows 7 x64 Maximum, but as it turned out, this is not so easy to do, I had to dig through a lot of pages on the Internet.

You cannot download Windows 7 from the official Microsoft website, since support for this product has stopped. At first I tried using a key to activate the Windows 7 operating system from the official Microsoft website, but due to the fact that support for this system was stopped, I could not do this and, accordingly, you will not be able to either.

Having started searching on the Internet, I was faced with the fact that I constantly came across “repacks” (modified versions of the OS by users) or versions with activators for Windows 7, but I needed exactly the original version of the OS without any activators added to it, since The original version works stably and without errors. And I’m used to activating Windows 7 using my own proven means.

If you are faced with a similar problem and you need the original version of Windows 7, then you can download it from our website completely free of charge. versions of Windows 7 x 64 Ultimate, as well as Windows x 86 Ultimate (for older computers), are available for download.

If you don’t know which version of the OS system you need, you can ask your question in the comments to the article, indicating the brand of your processor; I would like to note that all modern processors support Windows 7 x64.

You might be interested in an article about that, but I would like to note that the presented versions of Windows do not contain a built-in activator, as they are original boxed versions with a trial period, so you can use the 100% working version presented on this site.

USB 3.0 Driver Integration in Windows 7

After the release of the operating system, Microsoft stopped supporting the most common operating system today - Windows 7.

Because of this, many users began to face the problem that they could not install the Windows 7 operating system on modern computers and laptops via the USB interface, since the original distribution from 2016 did not have drivers for the USB 3.0 interface.

I have repeatedly responded in the comments to those who encountered this problem and wrote that to solve it they need to integrate USB 3.0 drivers into the Windows 7 installer. But many do not know how to do this and end up installing systems like this, completely refusing from the idea of installing Windows 7.

Since the integration of USB 3.0 drivers into Windows 7 takes quite a long time, I decided to relieve you of this burden and integrate a good package of USB 3.0 drivers into the original Windows 7 distributions presented on this site.

I did not make any more changes or additions to the distributions. I want to say right away that integrating USB 3.0 drivers into Windows 7 is not a solution to all problems.

There are situations in which, even after installing the Windows 7 operating system, you will not be able to install drivers for other equipment on your computer, since many manufacturers refuse to support Windows 7 on their devices and do not release drivers for it for a version lower, so keep this in mind .

Thus, we are being forced to stop using Windows 7, which, it seems to me, is not entirely correct for us, consumers.

Reading your comments, I realized that problems when installing Windows 7 via USB drives began to occur more and more often, so I decided to integrate USB 3.0 drivers into Windows 7 presented on this site, I hope this will help you.
