Windows 10 installation errors and solutions

Many users choose buy a Windows 10 key. Most download and use the operating system without problems, however, some encounter errors that may be due to various reasons. For example, with a lack of free space on a solid state or hard drive. 

In order to buy a Windows 10 key and install this operating system safely, it is useful to know the causes of common errors and how to fix them. This information is useful when booting a new OS and when reinstalling Windows.

Error 1: Operating system installation error

If a user has started installing Windows 10 and the application is unable to download the necessary files, this is often due to a bootable USB flash drive or DVD. The problem is solved in several ways, depending on its cause.

When the OS fails to install due to a faulty bootable media, it is recommended to use a different flash drive or DVD.

Sometimes the problem is related to the image of the system. If a person downloaded an OS repack instead of a clean version from the official Microsoft website, installation errors may occur. It is recommended that you download the system image only from the Microsoft website using trusted programs. For example, Media Creation Tool.

Sometimes the OS image is written to the media with an error because the PC has problems with RAM. In this case, to install Windows 10, you need to create bootable media on another computer.

Error 2: Missing device driver

This error can be due to several reasons. Often the problem is caused by the device from which the user installs the operating system. If we are talking about a USB connector, it is useful to try a different port. USB 2.0 is the best. When using a connector of this type, errors occur much less frequently than when connected via USB 3.0. It is also not recommended to use various extension cords and adapters.

Sometimes the installation of Windows 10 is interrupted by a message about the lack of a driver due to an incorrectly recorded system image. To solve the problem, it is important to download the OS image only from the official site. It is useful to burn boot files with different applications on several flash drives. This will increase the chance that at least one bootable media will work without errors.

Error 3: Failed to create partition to install operating system

If the OS installation application does not allow you to create a new partition for Windows 10, it usually means that another operating system was previously installed on it.

Solving this problem is simple. Copy all important files from the partition, and then delete it. After that, free space will appear from which you can create a new partition for installing Windows 10.

Error 4: Windows 10 update failed

When a user installs Windows 10 not through bootable media, but on an existing system, there may be a problem with the update. The reason is that the installer needs access to files and folders from the running OS. In this situation, you need:

  • disable antiviruses;
  • remove personal files and unnecessary programs from the system disk;
  • restart your PC and run the update again.

These steps should resolve the issue. If the error persists, it is recommended to update the system via bootable media.

Error 5: There is no free space on the hard drive

When users select a partition to install Windows 10, some get a message that they need to increase the size of the partition. To avoid this problem, it is important to prepare enough free space on your hard drive or solid state drive for the OS in advance.

Windows 10 requires at least 20 GB. Approximately 10 GB is needed for the system itself, and the remaining space allows you to install updates and third-party applications.

Error 6: Windows 10 activation error

Problems with the activation of the operating system can occur for various reasons. Most often, users encounter errors:

  • the system is not activated after a free upgrade from Win 7 or 8;
  • activation failed due to network problems;
  • activation is not possible because the key has exceeded the unlock limit.

If the user has upgraded from Windows 7 or 8.1 to Windows 10, there may be activation issues. This is usually due to the fact that older versions of the system were not licensed. In this case, it is recommended to buy a Windows 10 key and perform a clean install of the OS.

When activation is interrupted due to network issues, it is important to check your Internet connection. If the connection is not interrupted, the problem may be related to the firewall settings.

An error due to exceeding the key unlock limit means that this license can no longer be used. In such a situation, you need to buy a new key.


Although the installation of Windows 10 usually goes without problems, in rare cases errors occur that prevent you from using the system. Fortunately, many problems are relatively easy to solve. Therefore, any person can easily deal with installation errors if they correctly identify them and choose an effective solution.
