Getting started with a new or refurbished laptop often requires installing the operating system, which is impossible without access to bootable media. If you plan to reinstall Windows or Linux on your device Lenovo, you will need to correctly configure the system initialization process from an external device. This may seem like a difficult task due to the specifics of the interface BIOS and UEFI from a given manufacturer, however, if there is a clear algorithm of actions, the procedure becomes predictable.
Modern models Lenovo have several ways to enter the boot menu, from classic keyboard shortcuts to a physical button on the case. Incorrect actions can lead to the system simply ignoring the flash drive and continuing to boot from the hard drive, which will cause repeated reboots. We will analyze all the nuances in detail so that you can launch quickly and without errors. bootable media on your device.
Preparing a bootable USB flash drive and checking compatibility
Before you try to change your laptop settings, you need to make sure that your USB drive is completely ready to use. Mistakes at this stage often cause BIOS does not see the boot device or displays an error message. Make sure the flash drive is formatted to the correct file system, usually this is FAT32 for UEFI or NTFS for Legacy.
Check storage capacity: for modern versions Windows 10 or Windows 11 A minimum of 8 gigabytes of free space is required. If you are creating bootable media using the Media Creation Tool or Rufus, make sure that the correct partition scheme is selected: GPT for new laptops with the interface UEFI or MBR for older systems.
- 🔌 Use high-quality flash drives from well-known brands, as cheap media often lose data when overwritten.
- 💾 Check the integrity of the operating system image before recording to avoid installation errors.
- ⚡ Disconnect all unnecessary USB devices before starting the process to avoid confusion in the list of bootable media.
Methods to enter the Boot Menu and BIOS on Lenovo laptops
From manufacturers Lenovo There are several unique mechanical and software solutions for accessing boot settings. The fastest way is to use a special button New Button, which is often located at the end of the case next to the power connector or on the keyboard. It can be made in the form of a small hole that requires pressing with a paper clip, or a separate button with a curved arrow icon.
If the physical button is missing or does not work, you will have to use key combinations when turning on the device. For most models IdeaPad and ThinkPad the keys are relevant F12 or F2. It is important to press them repeatedly immediately after pressing the power button, without waiting for the Windows logo to appear. If you have Fastboot mode enabled, the window may appear for a split second, so some skill is required.
⚠️ Note: On some ThinkPad models, the F12 key may be disabled by default in the BIOS menu, so you will first need to go into settings and enable boot device selection.
Sometimes standard keys do not work because they are assigned to other functions (brightness adjustment, sound adjustment). In this case, you must hold down the key Fn and simultaneously press the function button, for example, Fn + F12. If the laptop is already booted into the system, you can try entering the settings through the Windows Settings menu, selecting Update & Security and holding Shift while clicking Restart.

Setting boot priority in the BIOS interface
Getting into the interface BIOS or UEFI, you will see a graphical or text interface, which may differ depending on the laptop series. The main task here is to find the tab responsible for the boot order of devices. Usually it is called Boot, Startup or Boot Priority. In this section, the list of devices is displayed in order of priority: at the top is the one from which the system will try to boot first.
To change the order, use the arrow keys and function keys listed at the bottom of the screen. Often these are keys F5 and F6 to move the selected item up or down the list. If you want to boot from a flash drive once, you can not change the priority, but select the device in the menu Boot Override, which is often found on the same tab. This is safer because it does not require permanent changes to be saved.
Pay attention to the operating mode of the download controller. If your laptop only supports UEFI, and the flash drive is written in the mode Legacy (CSM), it may not appear in the list. In the section Boot need to find a parameter Boot Mode and change it to UEFI or Legacy Support depending on the type of flash drive you have. This is a critical point for correct operation.
- 📂 Go to the tab
BootorStartupusing the navigation keys. - 🔄 Use
F5/F6to move the USB drive to the top of the list. - 🔒 Check the parameter
CSM(Compatibility Support Module), if the flash drive is not visible.
⚠️ Warning: If you change the boot mode from UEFI to Legacy or vice versa without preparation, the system may no longer boot from the hard drive and you will have to restore the bootloader.
☑️ Check settings before saving
Disabling Secure Boot and enabling CSM for compatibility
One of the most common problems when trying to boot from a flash drive is the function Secure Boot. This protection technology prevents unsigned or malicious code from running, but often blocks bootable media from third-party Linux distributions or older versions of Windows. To bypass this limitation, you need to go to the tab Security and find the parameter Secure Boot, setting its value to Disabled.
After disabling boot protection, you may need to activate compatibility mode CSM (Compatibility Support Module). This mode emulates the old BIOS, allowing you to boot from devices that do not support UEFI. Tab Boot contains parameter CSM Support, which needs to be switched to position Enabled. Without this step, the laptop may simply ignore the flash drive written in the classic MBR format.
Remember that after changing these settings you must save the changes and exit. This is usually done by pressing a key F10 and confirmation of action through selection Yes. The system will reboot and will now attempt to initialize booting from the connected USB drive if it has priority over the hard drive.
In some cases, especially on the business series ThinkPad, an administrative password must be set in the BIOS before changes to the security section can be made available. This is an additional security measure, but for simple OS installation operations it can be inconvenient. If you don't remember your password, it can be difficult to reset.
Why is CSM mode needed?
CSM mode allows older operating systems and utilities to run on modern UEFI motherboards by emulating the Legacy BIOS environment. This is necessary if your flash drive is not digitally signed for UEFI.
Disabling Secure Boot and enabling CSM are required steps for booting from flash drives that do not support modern UEFI architecture with digital signature.
Troubleshooting invisible flash drives
If after all the manipulations the flash drive does not appear in the list of boot devices, the problem may not only be in the BIOS settings. Sometimes it's the USB port itself or the controller drivers. Try connecting the drive to a different port, preferably USB 2.0, since USB 3.0 ports (usually blue) may not be initialized at boot if the drivers are not registered in UEFI.
It is also worth checking whether the image is recorded correctly. Utility Rufus has several recording modes: DD Image and ISO Image. DD Image mode often creates a flash drive that is visible as bootable only in specific cases, while ISO Image mode is more universal. Try overwriting the media using a different burning method and check the checksum of the downloaded image.
| Problem | Possible reason | Solution |
|---|---|---|
| The flash drive is not visible in the list | CSM mode disabled or Secure Boot enabled | Enable CSM and disable Secure Boot in BIOS |
| Error loading | Incorrect file system or partition scheme | Reformat to FAT32 (for UEFI) or NTFS (for Legacy) |
| The cursor is blinking and there is no loading | Boot sector damaged | Overwrite image using Rufus or Media Creation Tool |
| Loading only from HDD | Boot priority not changed | Check the Boot tab and move USB to first place |
Sometimes the problem lies in updating the BIOS firmware. An outdated version of microcode may have bugs that prevent the recognition of new types of drives. Go to the official website Lenovo Support, enter your laptop model and check for updates for BIOS. Installation is best done through running Windows, following the manufacturer's instructions.
If the flash drive is not detected in the BIOS, try writing the image to another flash drive, preferably of a smaller size and from a different manufacturer, to eliminate hardware incompatibility.
Alternative Method: Novo Button and System Restore
A unique feature of most laptops Lenovo is a button Novo Button. This is a physical switch that allows you to boot the system into the recovery menu without having to guess key combinations at startup. It is usually located on the left or right side of the case, next to the power button, and is indicated by a curved arrow icon. Use a paperclip or thin rod to press as the hole is very small.
When you press this button while the laptop is turned off, the device turns on and a menu appears with several action options. Here you can choose Normal Startup (normal startup) Bios Setup (enter settings), Boot Menu (device selection) or System Recovery (restoring from a factory copy). Choice Boot Menu instantly opens a list of available bootable media, eliminating the need to manually change priorities in the BIOS.
This method is especially convenient if your F12 or F2 keys do not work, or if you do not have time to press them in time. The Novo button works at the hardware level and ignores software failures of the operating system. This is the most reliable way to get to the desired menu on series devices IdeaPad, Yoga and Legion.
Use this option only as a last resort, when other methods do not help, or if you are ready to completely reinstall the system with data loss.
The Novo button is the fastest and most reliable way to access the boot menu on Lenovo laptops, bypassing keyboard and keypress timing issues.
