Many users are afraid to start the update process, considering it difficult or risky for the safety of personal files. In fact, if you follow a clear sequence of actions and preliminary preparation, the migration will go smoothly and without data loss.
In this article, we will examine in detail the two main update methods: through the built-in Update Center tool and a clean installation using bootable media. You will learn how to properly configure BIOSwhat drivers are needed for HP, Lenovo and ASUS laptops, and how to avoid common mistakes when reinstalling.
System preparation and data backup
Before you begin installing a new operating system, you must thoroughly prepare your laptop. The most common mistake users make is trying to update without saving important files, which can lead to their irretrievable loss in the event of a failure.
Make sure that your device has enough free space on the system drive, as the installation process requires a minimum of 20 gigabytes of free space. If you have a low-power laptop, empty the trash and delete temporary files via Control Panel → Disk Cleanup.
- 🔋 Connect the laptop to the power supply to prevent disconnection during the process.
- 💾 Copy all important documents to an external hard drive or cloud storage.
- 🔑 Write down the activation keys for the installed software, if any.
- 📶 Check the stability of your Internet connection to download updates.
⚠️ Attention: If you have a third-party antivirus installed on your laptop, temporarily disable it before starting the update so that it does not block the loading of system files.
Don't forget to check your hardware's compatibility with the new OS. Most devices released after 2012 support Windows 10, but older models may require manual driver updates.
Selecting an update method: Update Center or clean installation

Creating bootable media using the Media Creation Tool
If you choose a clean install, the first step is to create a bootable USB flash drive. To do this, you need to use the official tool from Microsoft called Media Creation Tool, which will automatically download the current version of the system.
Insert a flash drive of at least 8 GB into the USB port. Please note that all data on this media will be deleted during the image burning process, so use an empty memory card.
Run the utility and accept the license terms. In the action selection menu, check the “Create installation media for another computer” option. Next, select the language, edition, and system architecture compatible with your laptop.
| Parameter | Recommended value | Comment |
|---|---|---|
| System language | Russian (Russia) | For the convenience of the interface |
| Issue | Windows 10 | Suitable for most applications |
| Architecture | 64-bit (x64) | For Intel Core i3/i5/i7 and AMD Ryzen processors |
| Flash drive capacity | 8 GB or more | Minimum image requirement |
⚠️ Attention: If you have an old laptop with a 32-bit architecture processor, be sure to select the appropriate system edition, otherwise the installation will fail.
☑️ Creating a bootable USB flash drive
Setting up the BIOS and booting from a USB drive
After creating the flash drive, you need to change the boot order in BIOS or UEFI your laptop. This is a critical step, without which the computer will not see the installation disk.
Reboot your device and immediately start pressing the enter key repeatedly to enter the boot menu. These keys differ for different brands: ASUS this is usually F8 or Esc, y Lenovo — F12 or special button Novo, y HP — F9.
In the Boot Menu that opens, select your flash drive from the list of devices. If there is no such menu, you will have to go to the full BIOS interface, find the section Boot and move the USB device to the first position in the priority list.
- 🔌 Make sure the flash drive is inserted before turning on the laptop.
- 🔑 Disable Secure Boot in the security settings if the installation does not start.
- 💾 Save changes and exit BIOS by clicking
F10.
What to do if the laptop does not see the bootable USB flash drive?
Check if the flash drive was created correctly. Try a different USB port (USB 2.0 is better). You may need to disable Secure Boot or change the boot mode from UEFI to Legacy (CSM) in the BIOS settings.
If everything is done correctly, after rebooting the Windows logo will appear and the installer download process will begin. Do not remove the flash drive until the system asks you to do so.
The process of installing Windows 10 on a laptop
An installation window will appear in front of you. Select your language, time, and keyboard layout, then click the Install button.
