Modern laptop users often face the need to change the priority of the boot or check the temperature of the processor, which requires access to the basic I/O system. In devices from Xiaomi and the sub-brand RedmiBook, this process has its own features that differ from the usual schemes of other manufacturers.
In this article, we will discuss all the current ways of accessing the UEFI/BIOS You will learn not only about hotkeys, but also about software methods of logging in through the operating system, which is especially important for models with a high-quality computer. SSD-with a storage system that counts for milliseconds.
We will look at situations where the keyboard may not be able to respond, and suggest workarounds to solve the problem, and will also address the difference between the classic BIOS and the modern UEFI interface, which is used in most current models of the brand.
The main keys for entering the BIOS
The traditional and fastest way to get into firmware settings is to use a special key when starting the device. For the vast majority of Xiaomi Mi Notebook and RedmiBook laptops, the primary key is F2, which must be pressed immediately after power is turned on, before the Windows logo appears.
In some rare cases or on specific equipment modifications, you may need to use the Delete key or the Fn + F2 combination. However, statistics show that in 95% of cases, it is enough to rhythmically press the second functional key.
⚠️ Note: If you have fast boot mode enabled, the keystroke window may last less than a second, in which case a normal press may not work and you will need to use the method through the operating system described below.
There is also a less common option of logging in via the restore button, if any, with the design of a particular model, but for Xiaomi's line of laptops, this is more the exception than the rule.
💡
Try pressing the F2 key before you completely release the power button to win precious milliseconds.
Programmatic login via Windows 10 and 11 settings
If rhythmic keystroke does not work due to the high speed of loading SSD, the most reliable option is to use built-in Windows. Operating systems of the tenth and eleventh versions have a special mode of advanced boot, which allows you to go to UEFI without having to catch the start.
To do this, you need to go to the Start menu and select Settings (cog icon). Next, follow the Update and Security → Restore (for Windows 10) or System → Restore (for Windows 11). In the Special Boot Options section, click Reboot Now.
Once you reboot, you'll see a blue screen from the action menu. Select Find and troubleshoot, then go to Additional Settings. There'll be an option called "UEFI Embedded Software Options." When you click on it and confirm the reboot, the Xiaomi laptop will automatically start in BIOS configuration mode.
☑️ Login algorithm through Windows
This method guarantees you to log in to settings regardless of the drive speed or keyboard driver status, and is especially useful if you’re planning to make major changes to your system configuration.
Using the command line to reboot
For those who prefer to use hotkeys or terminals, there is a way to call the recovery menu via the command line, which allows you to skip several steps of the graphical interface of Windows settings and immediately go to the desired menu.
Open the command prompt with administrator rights or use PowerShell. Enter the following command to force reboot to Restore:
shutdown /r /o /f /t 00Once this command is executed, the system will immediately restart and be placed in the blue action menu described in the previous section. From there, you also choose the Search and Troubleshooting path → Additional options → UEFI firmware settings. This is the fastest software method that does not require wandering through the settings menu.
What to do if the laptop does not respond to the keys
The situation when Xiaomi laptop ignores the pressing F2, It can be caused not only by fast loading, but also by peripheral conflict. USB-Keyboards or mice can delay the initialization process by blocking the ability to input commands in a timely manner.
Try to turn off all external devices, leaving only the built-in laptop keyboard. It is also worth checking if any key is stuck, which can prevent the input controller from working correctly. In rare cases, a static charge reset helps: turn off the laptop, disconnect the charger and press the power button for 15-20 seconds.
⚠️ Warning: Do not attempt to disassemble a laptop or disable the loop of the built-in keyboard if the device is under warranty.Mechanical intervention may result in loss of warranty obligations.
If none of the software and physical methods work, the system bootloader files or the BIOS chip itself may be damaged. In this case, it is recommended to contact an authorized service center for diagnosis.
Set up the priority of downloading in the BIOS Xiaomi
Once in the BIOS/UEFI interface, users tend to change the order of loading devices to install a new operating system from a flash drive. The interface on Xiaomi laptops is usually graphic and intuitive, often supporting mouse control.
You need to find a section called Boot or Download. Inside that section will be a list of devices. Use the arrows on the keyboard or the mouse cursor to move your device. USB-drive to the top of the list. Don't forget to save the changes before you go out.
| Parameter | Description | Recommended value |
|---|---|---|
| Boot Option #1 | First loading device | USB / Windows Boot Manager |
| Fast Boot | Accelerated loading | Disabled (for installation of OS) |
| Secure Boot | Safe booting | Enabled (for Windows 10/11) |
| CSM Support | Support for legacy mode | Disabled (for UEFI) |
Importantly, to install modern versions of Windows, Secure Boot mode is better left on, and to install Linux distributions, it sometimes needs to be turned off. Be careful when changing these settings so that you don't disrupt the system.
💡
For successful installation of Windows 10/11 from the flash drive, Secure Boot mode can be left on, but the download priority should be given USB-device.
Resetting BIOS settings and exiting the menu
If you make a mistake during the setup process or the system starts to work unstable after changes, you can always go back to factory settings. In the BIOS interface of Xiaomi laptops, the Load Optimized Defaults option or the F9 button is usually responsible for this.
After resetting or successfully completing the configuration, you need to exit the menu correctly. This uses the F10 key, which causes a request to save the changes. Select Yes or Save & Exit to restart the computer with the new settings.
Do not turn off your laptop with the power button directly from the BIOS menu, as this can cause changes to not be written to non-volatile memory. Always use the standard log-out procedure through the menu or save hotkeys.
