Installing Windows on a Lenovo laptop: from BIOS to drivers

Installation Windows to laptops Lenovo - a process that seems simple only at first glance. Even experienced users are faced with nuances: from blocking boot from USB to BIOS before problems with drivers on IdeaPad or ThinkPad. This article will not just retell the standard instructions, but will reveal hidden UEFI settings for Lenovo, which the manufacturer does not advertise, and will show how to avoid common mistakes when installing on models with Secure Boot And Fast Boot.

We will analyze two scenarios: a clean installation with disk formatting and an update with saving files. We will pay special attention to laptops with NVMe drives (where Windows may not “see” the disk) and hybrid devices Lenovo Yoga with touch screens. If you have previously encountered the message “No bootable device» after installation - here you will find the solution.

1. Preparation: what you need to do before installing Windows

The first step is to check compatibility. Laptops Lenovo recent years (2018–2026) are officially supported Windows 10/11, but there are exceptions:

• 🔹 Models with ARM processors (For example, Lenovo ThinkPad X13s) require a special version of Windows 11 ARM.
• 🔹 Devices with Linux preinstalled (series IdeaPad 5 Pro) may have disk layout GPT with protected sections.
• 🔹 Laptops for the business line (ThinkPad P/T/X) often have BitLocker — it must be turned off in advance.

Download official Windows image from the Microsoft website (use Media Creation Tool). For Lenovo It is critical to choose the correct bit depth:

• 🔹 64-bit - for all modern models (even with 4 GB of RAM).
• 🔹 32-bit - only for obsolete Lenovo B/G series (2012–2015).

Please note: Windows 11 requires TPM 2.0 - its presence can be checked in BIOS (section Security → TPM Security).

⚠️ Attention: If you are installing Windows on a laptop with OEM license (for example, pre-installed Windows 10 Home), the product key is embedded in the BIOS. During a clean installation, the system is activated automatically - do not use third-party activators!

To create a bootable USB flash drive we recommend:

• 🔹 Rufus (version 3.22+) - for UEFI installation with support Secure Boot.
• 🔹 Ventoy — if you plan to test several images.
• 🔹 Official Media Creation Tool - for beginners (but does not support Lenovo with Legacy BIOS).

2. Setting up BIOS/UEFI on Lenovo laptops

This is where the main difficulties begin. Laptops Lenovo known to be "stubborn" BIOS, where standard keys (F2, Del) often do not work. Login methods:

• 🔹 ThinkPad: F1 (or Fn + F1 for new models).
• 🔹 IdeaPad/Legion: F2 or button Novo (next to food).
• 🔹 Lenovo Yoga: hold Shift when rebooting through the menu Start.

B BIOS You need to change the following parameters (paths may vary depending on the model):

On laptops Lenovo Legion and some IdeaPad there is a hidden menu Advanced BIOS. To open it:

1. Click Fn + Tab in the main menu BIOS.
2. Enter password: lenovo123 (for most 2020-2023 models).

In this menu you can disable Intel SGX (if it interferes with installation) or reset settings TPM.

3. Step-by-step installation of Windows

After setup BIOS and boot from the flash drive you will see the Windows Installer screen. Next we follow the algorithm:

1. Selecting a disk partition:

   On laptops Lenovo Hidden section is common Lenovo_Recovery (20–25 GB). You can remove it if you do not plan to return to the factory system. The main thing is not to touch the section EFI (100–500 MB), otherwise Windows will not boot.

   For NVMe drives (For example, Samsung PM981 in Lenovo ThinkBook) may require loading a storage driver. Download it in advance from official website (section Drivers & Software → Storage).

2. Formatting:

   Use NTFS for the system partition. If the installer offers ReFS - refuse (not supported on most Lenovo).

3. Installation process:

   During the “Prepare Files” stage, the laptop can freeze at 0% for 10–30 minutes - this is normal for models with Optane Memory (For example, Lenovo V15). Don't interrupt the process!

⚠️ Attention: If after a reboot the installer starts again, it means that the laptop is booting from the USB flash drive again. Remove it and manually select to boot from your hard drive in Boot Menu (key F12 when turned on).

4. Installing drivers and software for Lenovo

After installing Windows, you will have to “revive” the laptop - the following will not work without drivers:

• 🔹 Touchpad and gestures (especially on Lenovo Yoga with touch screen).
• 🔹 Function keys (Fn + F1–F12).
• 🔹 Keyboard backlight (on Legion And ThinkPad P-series).
• 🔹 Power management (modes Quiet/Performance on IdeaPad Gaming).

Download drivers only from the official website:

1. Go to Lenovo Support.
2. Enter the laptop serial number (located on the sticker below or in BIOS).
3. Select section Drivers & Software → specify the Windows version.
4. Download the package Lenovo System Update - it will automatically detect missing drivers.

For ThinkPad additionally install Lenovo Vantage - it controls proprietary functions, e.g. TrackPoint And Dolby Audio.

Important details:

• 🔹 Drivers NVIDIA/AMD It’s better to install from the manufacturer’s website (new versions give +10–15% performance in games).
• 🔹 On Lenovo Legion install first Lenovo Legion Toolkit — it unlocks the fan modes.
• 🔹 For IdeaPad with AMD Ryzen (For example, IdeaPad 5 15ARE05) download AMD Chipset Drivers manually - automatic updating skips them.

5. Optimizing Windows after installation

Laptops Lenovo often come with a "cut-down" version of Windows (lots of bloatware). After a clean installation, we recommend:

1. Disable unnecessary services:

• 🔹 Lenovo Vantage Service - if you do not use proprietary software.
• 🔹 Intel Rapid Storage Technology - if you have an SSD without Optane.
• 🔹 NVIDIA Telemetry — collects data on GPU usage.

Open Start → Services (services.msc) and set the startup type Manually.

2. Set up power:

For Lenovo Legion And ThinkPad P-series:

1. Go to Control Panel → Power Options.
2. Select a scheme High performance.
3. Click Set up power plan → Change advanced settings.
4. Install:
   • 🔹 PCI Express → Link State Power Management → Off
   • 🔹 Processor → Maximum processor state → 100%

This will increase FPS in games by 5-10% and eliminate lag when working with heavy applications.

3. Update BIOS:

Firmware BIOS on Lenovo solves many problems:

• 🔹 Fixes bugs with Thunderbolt 4 (relevant for ThinkPad X1 Carbon).
• 🔹Adds support for new processors (for example, Intel 13th generation on Legion 7).
• 🔹 Eliminates sleep bugs (Sleep Mode).

Instructions:

1. Download the firmware from the website Lenovo (section BIOS/UEFI).
2. Unpack the archive and run .exe-file as administrator.
3. Follow the instructions and the laptop will reboot automatically.

⚠️ Attention: Don't interrupt the update process BIOS and do not connect the laptop to the docking station. Use the original power supply - when upgrading via USB-C (Lenovo Yoga 9i) failures are possible.

6. Solving common errors after installation

Even when installed correctly Lenovo problems may arise. Let's look at the most common ones:

1. «No Audio Output Device Installed»

Reason: driver missing Realtek Audio or Dolby Atmos. Solution:

• 🔹 Download the driver from the website Lenovo (section Audio).
• 🔹 For ThinkPad additionally install Lenovo Audio Driver (it includes array microphone support).
• 🔹 If there is sound, but it’s quiet, turn it off Dolby Audio in the tray.

2. Function keys do not work (Fn)

The culprit is absence Hotkey Driver. Download:

• 🔹 For IdeaPad: Lenovo Function Keys Driver.
• 🔹 For ThinkPad: Lenovo Hotkey Features Integration.
• 🔹 For Legion: Lenovo Legion TrueStrike Keyboard Driver.

3. The laptop does not wake up from sleep mode

A common problem on Lenovo Yoga And IdeaPad Flex. Solution:

1. Open Device Manager (devmgmt.msc).
2. Expand System devices.
3. Find Intel Management Engine Interface → update the driver.
4. B Power supply turn off Quick start.

4. Overheating and fan noise

On Lenovo Legion And ThinkPad P-series:

• 🔹 Install Lenovo Legion Toolkit or ThrottleStop for manual control of fans.
• 🔹 Update EC Firmware (section BIOS/UEFI on the website Lenovo).
• 🔹 Clean the dust (on Legion 5 fans become clogged within 6–12 months).

7. Restoring factory Windows (if something went wrong)

If after installation the laptop is unstable, you can return the factory system. On Lenovo there are two ways:

1. Via hidden recovery partition

Suitable if you did not delete the section Lenovo_Recovery:

1. Turn off your laptop.
2. Click the button Novo (next to the power button) or F11 when turned on.
3. Select System Recovery → Restore from initial backup.

The process will take 20–40 minutes. All data on disk C: will be erased!

2. Using an image from the Lenovo website

If the recovery partition is damaged:

1. Go to support site.
2. Enter serial number → Downloads → Recovery Media.
3. Download the image and write it to a flash drive via Rufus.
4. Boot from the flash drive and follow the instructions.

Please note: Recovery images are 10-16 GB in size and contain all original drivers and software.

⚠️ Attention: On laptops Lenovo with Windows 11 preinstalled (For example, ThinkBook 14+) the recovery partition can be encrypted BitLocker. To use it, first disable encryption in Control Panel → System and Security → BitLocker Drive Encryption.
