No one is immune, for example, from a sudden voltage drop in the network, a power outage, or simply a failure in the program itself. So we still advise you to copy all valuable information to a flash drive or disk.

How about 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. By at least, many experts think so.

What does installing from a boot drive mean?

7 without disk? The standard installation model for any operating system occurs with hard media. 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 it was placed old system. 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 should run special program. It is necessary for reading/writing exactly this kind of formats. Eg, 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 in 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 installation working system is performed for the first time, some rules should be taken into account. 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 with this type of installation working environment don't disappear anywhere. They are saved in the previous installed system. Subsequently, they will simply switch to a new shell.

Secondly, the best, and most importantly, the most in a safe way there will still be installations use of hard carrier. 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 actions. 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? Please remember that when installing 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 it the most in a simple way. Find the folder with the operating system and run installation file. After this, the installation window will open. It will display the ability to configure the following settings:

selecting the system language (this is the language of the displayed names of folders, files, disks, and so on);
keyboard layout (input language);
time format (country, time zone).

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 the installation, go to 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:

home - for an inexperienced user;
standard - for those who confidently work with a computer;
professional - for an experienced person; it offers extensive capabilities, necessary modules and great access to files;
maximum - provides full access to all the functionality of the operating system.

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 size random access memory 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 to complete it on your computer and update. It is necessary to make a choice in favor complete installation. Otherwise, only an update to the pre-existing operating system will occur.

After selection preliminary parameters a window appears with a choice 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 situation old system will remain in the folder " Windows old". It will be located on the “C” drive. You can also start and work from it. But this is not recommended, since two identical operating systems on the same disk may “conflict.” This, in turn, will lead to a failure in operation. The old OS can be removed or moved to another medium. Here is another very significant moment, which should be remembered when answering the question of how to reinstall Windows 7 without a disk on Asus laptop, 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 various types defragmenters. For example, the Victoria program.

This problem is not so bad for computers. Nothing is easier than buying new hard disk and install 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 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:

Username (your own name or a desired nickname).
Computer name (any name in Latin or Russian letters).

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 it will be possible to activate the system by any in a convenient way. This is done as follows:

You need to find the "My Computer" folder.
You need to open it by clicking on right button mice.
You need to click on the "Properties" tab.
You should select the “Change product key” option.

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 security settings. You can use the recommended service, or you can postpone the decision and configure it later. Computer protection is one of the most important moments in installing the 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 set up 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. Concerning common understanding, That 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?

It was last step, after which you will get an almost empty desktop of the newly installed operating system Windows systems 7. Basic settings (for example, adding the “My Computer” folder or user files to the desktop) can be made by left-clicking on the desktop space and selecting the “Personalization” tab.

You can put another one there too background picture, change the default theme (usually Windows 7 Aero), change the screen resolution and much more.
