First steps

After clicking the "Next" button, a window opens with the "Install" button. Having clicked on installation, we pass to the license agreement. We accept it by putting a checkmark next to the corresponding inscription.
The most popular types of systems
The installer may contain several system options. Most commonly used:
- home - for an inexperienced user;
- standard - for those who work confidently with a computer;
- professional - for an experienced person; it offers ample opportunities, the necessary modules and great access to files;

If you were wondering about how to reinstall Windows 7 without a disk and a flash drive on a laptop or computer, then you should understand that this is an incomplete list of possible systems.
Do not forget about bit depth
All programs of this type are distinguished by their capacity, that is, 32-bit (X86) and 64-bit (X64). This parameter is indicated after the system name. For example, Windows 7 Maximum X86.
The choice of the discharge of the installed system should be done, guided by the power of computer resources. If the laptop or PC is relatively weak, it is recommended to install the X86 OS (32-bit version). Installing Windows 7 X64 is best if the size of RAM 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 window of the OS installer will offer the option of a complete installation of the system on your computer and update. You must opt for a complete installation. Otherwise, only the pre-existing operating system will be updated.
After selecting the preliminary parameters, a window appears with the ability to select a hard disk. With this method, you cannot format it. This is due to the fact that the installer was launched from a working system. If you need to format the disk, which is desirable when installing the OS, then this point can be circumvented. It happens as follows. Until the installation of the new “seven”, take any other disk partition and clean it from the files (move if you need them, and just don’t touch them if you don’t need them). After that, format the section. You should not change the drive letter in this situation. Answering the question of how to reinstall Windows 7 without a disk and a flash drive on a laptop or computer, it should be borne in mind that when the new system boots up, the letters of the disks will change automatically. The formatted partition should be selected to install the system.
If cleaning is not needed
If formatting is not necessary, you can simply select the drive to install the new system and continue. In this situation, the old system will remain in the "Windows old" folder. It will be located on drive "C". From it, you can also start and work. But to do this is not recommended, since two identical operating systems on the same disk can "conflict". This, in turn, will entail a malfunction. An old OS can be deleted or moved to another medium. Here is another very significant point that should be remembered when answering the question of how to reinstall Windows 7 without a disk on an Asus, Lenovo, HP, etc. laptop.
If there is not enough space for two operating systems in the partition on which the new OS is installed, the installation process will not start. This is 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 "OS" leads to the destruction of the disk. This can be avoided by using various 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 on your own. However, if the hard drive broke down on a laptop, then, in addition to the cost of the drive 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 USB flash drive.
What do you need to enter after installation?
After selecting the drive (partition) to install, click Next, which will unpack and install 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:
- Username (your own name or desired alias).
- Computer name (any name in Latin or Russian letters).
If the input is incorrect, the system will say this and ask you to correct the characters, indicating an error.
Password and Key Entry
During installation, you will be prompted to assign a password and a hint in case it is lost. After that, a window pops up in which you should enter the key to activate the operating system. If it’s absent, simply click “Next”, having previously unchecked the box next to “Activation when connected to the Internet”. Then it will be possible to activate the system in any convenient way. This is done as follows:
- Find the My Computer folder.
