Many users are afraid of this process, believing that they will lose important data or will not be able to find drivers. In fact, modern solutions from Lenovo have greatly simplified the task by providing built-in tools and convenient recovery menus that are accessible even to a beginner.

In this article we will analyze all the nuances: from preparing the media to the final setup of the system. You will learn how to correctly delete old files, install the latest version of the operating system, and avoid the most common mistakes when working with BIOS and boot devices.

Equipment preparation and backup

Before you take drastic action, you need to prepare your workspace and save all valuable files. The installation process can take anywhere from 30 minutes to several hours depending on the speed of your drive and the type of drive you are using.

You will need a flash drive of at least 8 GB, which will be formatted. It is also critical to ensure that the laptop Lenovo connected to a power source, since draining the battery in the middle of the process can lead to fatal damage to system files.

Back up your documents, photos, and settings to an external hard drive or cloud storage. Remember that after formatting the partition C: It will be almost impossible to recover data without special software.

• 📂 Copy personal files to external storage or to the cloud
• 💾 Prepare an empty flash drive of 8 GB or more
• 🔌 Connect your laptop to the network and charge the battery to 100%
• 🔑 Write down your Windows license key if it is not linked to your account

⚠️ Attention: Do not use flash drives that store important data to create bootable media, as they will be permanently deleted during the process of recording the system image.

Creating bootable media and choosing a method

To install Windows 10 on Lenovo There are two main ways: using the built-in recovery function or creating a flash drive through the official Microsoft Media Creation Tool. The first method is simpler, but the second gives more control over the system version.

If you decide to use the standard Microsoft tool, download the utility from the official website. Run it, accept the license agreement and select the “Create installation media” option. Make sure the language and architecture (usually x64) meet your requirements.

After selecting the flash drive, the program will automatically download the system image and prepare a boot disk. This may take time depending on your internet speed. Don't interrupt the process, even if the program seems to be stuck.

• 🌐 Download Media Creation Tool from Microsoft website
• 💿 Select the option “Create installation media for another PC”
• 🚀 Wait until the image is written to the flash drive

Features of downloading on Lenovo

On most Lenovo laptops, you need to press the F12 key or the special Novo Button (the small hole next to the power button or on the side of the case) to enter the boot menu.

Setting up the BIOS and booting from media

The most difficult step for beginners is setting up the BIOS/UEFI to boot from a flash drive. On laptops Lenovo a proprietary shell is often used, which may differ from the standard interface of other manufacturers.

Reboot your device and immediately start pressing the key frequently F1 or F2to get into the BIOS settings. Some models use a button F12 to select a boot device on the fly, which is much easier.

In the section Boot or Startup find the list of devices. Move your flash drive to the top of the list using the arrow keys or F5/F6. It's also important to turn off Secure Boot only if you are installing a non-original assembly, this is not required for the official version.

Настройки BIOS: Advanced → Boot → USB HDD → [Ваша флешка] → F10 для сохранения

• ⌨️ Click F12 when turned on to select boot device
• 🔧 In BIOS, check the boot mode UEFI (not Legacy)
• 🔑 Save changes with the button F10 and confirm reboot

⚠️ Attention: If you do not know how to properly configure the BIOS, it is better to use the Novo Button function on the laptop case, which will automatically offer the boot menu without complex settings.

Installation process and disk partitioning

After successful download, you will see the Windows installation window. Select your language, time, and keyboard layout, then click Install. Enter your product key if you have one, or select "I don't have a product key" to activate later.

Select the installation type "Custom: Windows installation only". This is where the most crucial moment begins - working with disks. You will see a list of partitions on your hard drive or SSD.

For a clean installation, it is recommended to delete all existing partitions on the system disk to obtain an unallocated area. This will remove all old drivers, viruses and junk. Be extremely careful not to delete data partitions on other drives.

Select each partition associated with the system drive (usually drive 0) and click the “Delete” button. When only one line “Unallocated disk space” remains, select it and click “Next”. The system itself will create the necessary service partitions.

• 🗑️ Delete all old partitions on the system disk (Disk 0)
• 💾 Select “Unallocated Space” and click “Next”
• ⏳ Wait for the files to be copied and the device to reboot

After rebooting, the flash drive will no longer be needed. The system will continue with the setup, create temporary files, and prompt you to set up your account.

⚠️ Warning: If you do not delete the old partitions, the system may install Windows on the new partition, leaving the old files on the disk, which will create confusion and take up unnecessary space.

Installing drivers and setting up Lenovo Vantage

After logging in for the first time, you need to take care of the drivers. Windows 10 will automatically install basic drivers, but for the laptop to fully function Lenovo specific components are required.

Download and install the application Lenovo Vantage from the Microsoft Store. This utility automatically scans the system, finds missing drivers, BIOS updates, and utilities specific to your model.

Pay special attention to chipset drivers, sound and video card. If the automatic search does not work, go to the official Lenovo support site, enter the serial number of the device and download the required packages manually.

• 📥 Download Lenovo Vantage from the app store
• 🔄 Run a system scan and update all components
• 🎮 Install video card drivers from NVIDIA or AMD manually

It is also recommended to check your power settings. Balanced mode will keep your laptop running optimally, but if you want maximum performance, switch to High Performance mode.

⚠️ Attention: Do not install drivers from third-party automation programs, as they may replace the original Lenovo drivers with outdated versions, which will lead to unstable operation.

Solving common problems and nuances

Sometimes errors such as “Media device driver not found” or a blue screen may occur during the installation process. This is often due to the fact that the BIOS mode is enabled Legacy, and the system requires UEFI, or vice versa.

Another common problem is the lack of a driver for the disk. In this case, go to the support site, download the Intel RST (Rapid Storage Technology) driver and copy it to the installation flash drive. In the disk selection window, click “Load” and specify the path to the file.

If after installation the system slows down, check whether there is a lot of unnecessary software installed by default (Bloatware). Use a clean installation or remove unnecessary programs through Options.

• 🔧 Check boot mode in BIOS (UEFI/Legacy)
• 📂 Prepare the RST driver on the flash drive when receiving the “Disk not found” error
• 🧹 Remove pre-installed software that you don’t need

What should I do if the keyboard does not work during installation?

If the keyboard does not respond, try connecting an external USB keyboard. Sometimes this is due to missing USB controller drivers during the installation phase, but most often the problem is resolved by updating the BIOS to the latest version before starting the process.

Also don't forget to activate Windows. If you had a licensed version linked to a Microsoft account, the system is activated automatically when you connect to the Internet.

⚠️ Attention: If you change the motherboard or laptop model, the license binding may be reset and you will need to enter a new key or purchase a new license.
