How to properly change Windows on a laptop: a complete guide with nuances

Reinstalling the operating system on a laptop is a task that every user faces sooner or later. The reasons may be different: from virus infection to the desire to update to the latest version Windows 11 or return to verified Windows 10. However, the process has its own characteristics compared to desktop PCs: drivers for Wi-Fi, touchpad and other components, as well as taking into account the specifics BIOS/UEFI specific model.

This article won't just list the installation steps - we'll walk you through critical errors that lead to a “black screen” after reinstallation for 37% of laptop users, we’ll show you how to save your Windows license, and give you a checklist for preparation. We will pay special attention to laptops Lenovo, HP, Asus And Acer, where the process may differ due to proprietary recovery technologies.

1. Preparing for reinstallation: what to do before formatting the disk

The first and most important step is data backup. Even if you plan to install Windows on a separate partition, an error when selecting a drive can lead to file loss. Use an external drive or cloud storage to save:

• 📁 Documents from folders Desk, Downloads, My documents
• 🔑 Program license files (especially Adobe, Microsoft Office)
• 🎮 Game saves (usually located in %AppData% or Documents\My Games)
• 📋 Export browser bookmarks and passwords (to Chrome this is done through chrome://settings/exportBookmarks)

The next step is to check the laptop's compatibility with the selected version of Windows. For example, Windows 11 requires TPM 2.0 And Secure Boot, which can be disabled in the BIOS. To check:

1. Click Win + R, enter msinfo32
2. Check the lines "BIOS Mode" (should be UEFI) and "Secure Boot Status" (On)
3. For TPM enter on the command line:

   tpm.msc

Don't forget about the drivers! After installing Windows you will need:

• 🖱️ Touchpad driver (especially relevant for Dell XPS And HP Spectre)
• 📶 Network driver (Wi-Fi or Ethernet)
• 🔊 Audio driver (often missing from the standard Windows set)

2. Creating a bootable USB flash drive: 3 proven methods

To install Windows, you will need a bootable USB drive with at least a capacity of 8 GB. Let's look at three methods for creating it:

Method	Pros	Cons	Suitable for
Media Creation Tool (official Microsoft utility)	Automatic download of the latest version, error checking	Requires stable internet, no version choice	Beginner users
Rufus (v3.22+)	UEFI/GPT support, ability to remove TPM requirement for Windows 11	More difficult for beginners, risk of errors during setup	Advanced users
Ventoy	Multiboot flash drive (can burn multiple ISOs), does not format the drive	Less automation, requires manual configuration	IT specialists

Optimal for most users Rufus. Instructions for creating a flash drive:

1. Download Rufus from the official website and the latest version of Windows with Microsoft website.
2. Insert the flash drive and run Rufus. Select:
• Device: your flash drive
• Download Method: Select the downloaded ISO file
• Section layout: GPT
• Target system: UEFI (non-CSM)

For Windows 11, uncheck "Requires TPM 2.0" in advanced settings.

Click START and wait for completion (10-30 minutes).

What to do if Rufus does not see the flash drive?

Check the connection to USB 2.0 (blue port), disconnect other drives, try formatting the flash drive in FAT32 via diskpart (commands: list disk → select disk X → clean → create partition primary → format fs=fat32 quick).

3. Setting up BIOS/UEFI: how not to block your laptop

这里最危险的阶段 - incorrect BIOS settings can cause the laptop to stop booting even from a flash drive. Main parameters to check:

• 🔒 Secure Boot: for Windows 11 - enable, for Windows 10/Linux - can be disabled
• 💾 Boot Mode: set UEFI (not Legacy/CSM)
• 🔑 TPM: for Windows 11 - enable (in the section Security or Advanced)
• 🔄 Fast Boot: disable (may interfere with booting from a flash drive)

How to enter BIOS on different laptops:

• Lenovo: F2 or Fn + F2 (on some models the button Novo Button next to food)
• HP: Esc → F10 (or F9 for boot menu)
• Asus: F2 or Del
• Acer: F2 or Del (on some models F12 for boot menu)
• Dell: F12 when loading (or F2 for BIOS)

⚠️ Attention: On laptops Lenovo Legion and some HP Omen After changing BIOS settings, you may be required to enter a verification code. Prepare in advance a second device with Internet access to generate the code via Lenovo Vantage or HP Support Assistant.

4. Windows installation process: step by step with photos

After successfully booting from the USB flash drive, you will see the Windows Installer window. Follow these steps:

1. Language selection: Leave Russian (or select the one you need), the time format corresponds to your country.
2. Product Key:
   • If you have OEM license (tied to the motherboard), click “I don’t have a product key” - activation will occur automatically after connecting to the Internet.
   • For retail versions enter the key or select the desired edition (Pro/Home).
3. Installation type: Select "Custom: Windows installation only".
4. Disk partitioning:
   • Delete all partitions (except the hidden one) EFI size ~100-500 MB).
   • Select the unallocated space and click "Next" - Windows itself will create the necessary partitions.

The process of copying files and setting will take 20-40 minutes. The laptop may reboot several times - this is normal. Do not remove the flash drive before your first login!

After installation is complete:

5. Select your region and keyboard layout.
6. Connect to Wi-Fi (if the network card driver is installed).
7. Configure your privacy settings (you can disable all but the required ones).
8. Create a local account or sign in Microsoft Account (recommended for synchronizing settings).

5. Installing drivers: why the touchpad and Wi-Fi don’t work

A freshly installed Windows rarely recognizes all laptop components automatically. Priority order for installing drivers:

1. Chipset (Motherboard Driver) - the basis for the operation of other drivers.
2. Video card:
   • For NVIDIA: download from official website.
   • For AMD: use AMD Adrenalin.
   • For Intel Iris Xe: driver goes through Windows Update.

Network adapters (Wi-Fi and Ethernet) - without them there will be no Internet for other updates.

Audio (often Realtek Audio Console).

Touchpad (especially important for Precision Touchpad on Dell XPS And HP Envy).

Where to download drivers:

• 🔧 Official website of the laptop manufacturer (enter model in search).
• 🔄 Windows Update (click Win + I → Update and Security).
• 🛠️ Auto-update utilities:
  • Lenovo Vantage / MyASUS / HP Support Assistant
  • Driver Booster (for advanced users only)

⚠️ Attention: On laptops Asus ROG And MSI After installing the video card drivers, the image on the built-in display may disappear. In this case, connect an external monitor via HDMI and roll back the driver via Device Manager.

6. Optimizing Windows after installation: 7 mandatory steps

Clean Windows works quickly, but without proper configuration, after a month you will notice slowdowns. What to do immediately after installation:

1. Autoload: Click Ctrl + Shift + Esc → "Startup" tab. Disable everything except your antivirus and device drivers. For example, NVIDIA GeForce Experience And Realtek Audio Manager can be started manually.

2. Swap file:

• For 8 GB RAM: Set to fixed size 8192 MB.
• For 16 GB+: can be disabled or set 2048 MB.

Setting: Control Panel → System → Advanced system settings → Performance → Settings → Advanced → Virtual memory.

3. Power supply:

• For maximum performance, select "High performance".
• On laptops with Optimus (For example, Asus TUF) in NVIDIA Control Panel set "NVIDIA adapter"as the main one for games.

4. Updates:

• Open Settings → Update & Security.
• Install all available updates (especially KB5027231 for Windows 11 - fixes battery problems).
• Disable automatic driver downloads via Windows Update (they are often outdated).

7. Solving common problems after reinstallation

Even with proper installation, problems may occur. Let's look at the most common ones:

Problem	Reason	Solution
Touchpad doesn't work	Driver missing Synaptics or ELAN	Download from the manufacturer's website or install via Device Manager (update driver → search on this computer → select from list)
No sound	Driver not installed Realtek Audio or the service is disabled Windows Audio	Check services.msc (the service must be running). Install the driver from the official website.
The laptop gets very hot	Chipset drivers are not installed or running in maximum performance mode	Install Intel Management Engine or AMD Chipset Driver. Use ThrottleStop to configure undervolting.
Keyboard doesn't work	Driver conflict or disabled in BIOS	Check the BIOS section Advanced → Keyboard/Mouse Features. Reinstall the driver via Device Manager.

For laptops with hybrid graphics (For example, Intel + NVIDIA) you may need to manually configure the switchable graphics:

1. Install the latest drivers from the website NVIDIA.
2. B NVIDIA Control Panel select "Managing 3D Settings" → "Software settings".
3. Add the necessary programs (games, editors) and install for them "High performance NVIDIA processor".

8. How to restore factory settings if something goes wrong

If after reinstalling Windows your laptop is unstable or you have lost important data, you can return it to factory settings. Most manufacturers have a hidden recovery partition:

• Lenovo: Click Novo Button (next to the power button) → "System Recovery".
• HP: When loading, press F11 → "Troubleshoot" → "Recovery Manager".
• Asus: F9 on boot → "Windows Setup [EMM]".

⚠️ Warning: Restoring factory settings will delete all data on the disk C:! Save important files to an external drive first. On some laptops (eg Dell XPS 13) The recovery process may take up to 2 hours - do not interrupt it.

After recovery you will need:

1. Update Windows via Settings → Update & Security.
2. Install the missing drivers (see section 5).
3. Activate Windows (if it does not happen automatically).

FAQ: Answers to frequently asked questions

Is it possible to install Windows 11 on a laptop without TPM 2.0?

Yes, but Microsoft does not officially support such installations. Workarounds:

1. Use Rufus with disabling TPM checking when creating a flash drive.
2. When installing manually, create a registry key:

   Regedit → HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig
   Создать параметры DWORD:
   - BypassTPMCheck = 1
   - BypassSecureBootCheck = 1
   - BypassRAMCheck = 1

However, without TPM you will not be able to receive security updates through Windows Update.
